/**

* @brief ASID management.
*
* Modern processor architectures optimize TLB utilization
* by using ASIDs (a.k.a. memory contexts on sparc64 and
* region identifiers on ia64). These ASIDs help to associate
* each TLB item with an address space, thus making
* finer-grained TLB invalidation possible.
*
* Unfortunatelly, there are usually less ASIDs available than
* there can be unique as_t structures (i.e. address spaces
* recognized by the kernel).
*
* When system runs short of ASIDs, it will attempt to steal
* ASID from an address space that has not been active for
* a while.
*
* This code depends on the fact that ASIDS_ALLOCABLE
* is greater than number of supported CPUs (i.e. the
* amount of concurently active address spaces).
*
* Architectures that don't have hardware support for address
* spaces do not compile with this file.

* This trap handler makes arrangements to make calling of scheduler() from

*
* This function can be entered either with interrupt globals or alternate
* globals. Memory management trap handlers are obliged to switch to one of
* those global sets prior to calling this function. Register window management
* functions are not allowed to modify the alternate global registers.
*
* The kernel is designed to work on trap levels 0 - 4. For instance, the
* following can happen:
* TL0: kernel thread runs (CANSAVE=0, kernel stack not in DTLB)
* TL1: preemptible trap handler started after a tick interrupt
* TL2: preemptible trap handler did SAVE
* TL3: spill handler touched the kernel stack
* TL4: hardware or software failure
*
* Input registers:
* %g1 Address of function to call if this is not a syscall.
* %g2 First argument for the function.
* %g6 Pre-set as kernel stack base if trap from userspace.
* %g7 Pre-set as address of the userspace window buffer.

/* IPC resources management
*
* The goal of this source code is to properly manage IPC resources and allow
* straight and clean clean-up procedure upon task termination.
*
* The pattern of usage of the resources is:
* - allocate empty phone slot, connect | deallocate slot
* - disconnect connected phone (some messages might be on the fly)
* - find phone in slot and send a message using phone
* - answer message to phone
* - hangup phone (the caller has hung up)
* - hangup phone (the answerbox is exiting)
*
* Locking strategy
*
* - To use a phone, disconnect a phone etc., the phone must be first locked and
* then checked that it is connected
* - To connect an allocated phone it need not be locked (assigning pointer is
* atomic on all platforms)
*
* - To find an empty phone slot, the TASK must be locked
* - To answer a message, the answerbox must be locked
* - The locking of phone and answerbox is done at the ipc_ level.
* It is perfectly correct to pass unconnected phone to these functions and
* proper reply will be generated.
*
* Locking order
*
* - first phone, then answerbox
* + Easy locking on calls
* - Very hard traversing list of phones when disconnecting because the phones
* may disconnect during traversal of list of connected phones. The only
* possibility is try_lock with restart of list traversal.
*
* Destroying is less frequent, this approach is taken.
*
* Phone call
*
* *** Connect_me_to ***
* The caller sends IPC_M_CONNECT_ME_TO to an answerbox. The server receives
* 'phoneid' of the connecting phone as an ARG5. If it answers with RETVAL=0,
* the phonecall is accepted, otherwise it is refused.
*
* *** Connect_to_me ***
* The caller sends IPC_M_CONNECT_TO_ME.
* The server receives an automatically opened phoneid. If it accepts
* (RETVAL=0), it can use the phoneid immediately.
* Possible race condition can arise, when the client receives messages from new
* connection before getting response for connect_to_me message. Userspace
* should implement handshake protocol that would control it.
*
* Phone hangup
*
* *** The caller hangs up (sys_ipc_hangup) ***
* - The phone is disconnected (no more messages can be sent over this phone),
* all in-progress messages are correctly handled. The answerbox receives
* IPC_M_PHONE_HUNGUP call from the phone that hung up. When all async
* calls are answered, the phone is deallocated.
*
* *** The answerbox hangs up (ipc_answer(EHANGUP))
* - The phone is disconnected. EHANGUP response code is sent
* to the calling task. All new calls through this phone
* get a EHUNGUP error code, the task is expected to
* send an sys_ipc_hangup after cleaning up its internal structures.
*
* Call forwarding
*
* The call can be forwarded, so that the answer to call is passed directly
* to the original sender. However, this poses special problems regarding
* routing of hangup messages.
*
* sys_ipc_hangup -> IPC_M_PHONE_HUNGUP
* - this message CANNOT be forwarded
*
* EHANGUP during forward
* - The *forwarding* phone will be closed, EFORWARD is sent to receiver.
*
* EHANGUP, ENOENT during forward
* - EFORWARD is sent to the receiver, ipc_forward returns error code EFORWARD
*
* Cleanup strategy
*
* 1) Disconnect all our phones ('ipc_phone_hangup').
*
* 2) Disconnect all phones connected to answerbox.
*
* 3) Answer all messages in 'calls' and 'dispatched_calls' queues with
* appropriate error code (EHANGUP, EFORWARD).
*
* 4) Wait for all async answers to arrive and dispose of them.

/**
* @file
* @brief IRQ notification framework.
*
* This framework allows applications to register to receive a notification
* when interrupt is detected. The application may provide a simple 'top-half'
* handler as part of its registration, which can perform simple operations
* (read/write port/memory, add information to notification ipc message).
*
* The structure of a notification message is as follows:
* - METHOD: method as registered by the SYS_IPC_REGISTER_IRQ syscall
* - ARG1: payload modified by a 'top-half' handler
* - ARG2: payload modified by a 'top-half' handler
* - ARG3: payload modified by a 'top-half' handler
* - ARG4: payload modified by a 'top-half' handler
* - ARG5: payload modified by a 'top-half' handler
* - in_phone_hash: interrupt counter (may be needed to assure correct order
* in multithreaded drivers)
*
* Note on synchronization for ipc_irq_register(), ipc_irq_unregister(),
* ipc_irq_cleanup() and IRQ handlers:
*
* By always taking all of the uspace IRQ hash table lock, IRQ structure lock
* and answerbox lock, we can rule out race conditions between the
* registration functions and also the cleanup function. Thus the observer can
* either see the IRQ structure present in both the hash table and the
* answerbox list or absent in both. Views in which the IRQ structure would be
* linked in the hash table but not in the answerbox list, or vice versa, are
* not possible.
*
* By always taking the hash table lock and the IRQ structure lock, we can
* rule out a scenario in which we would free up an IRQ structure, which is
* still referenced by, for example, an IRQ handler. The locking scheme forces
* us to lock the IRQ structure only after any progressing IRQs on that
* structure are finished. Because we hold the hash table lock, we prevent new
* IRQs from taking new references to the IRQ structure.

*
* Print string formatted according to the fmt parameter and variadic arguments.
* Each formatting directive must have the following form:
*
* \% [ FLAGS ] [ WIDTH ] [ .PRECISION ] [ TYPE ] CONVERSION
*
* FLAGS:@n
* - "#" Force to print prefix. For \%o conversion, the prefix is 0, for
* \%x and \%X prefixes are 0x and 0X and for conversion \%b the
* prefix is 0b.
*
* - "-" Align to left.
*
* - "+" Print positive sign just as negative.
*
* - " " If the printed number is positive and "+" flag is not set,
* print space in place of sign.
*
* - "0" Print 0 as padding instead of spaces. Zeroes are placed between
* sign and the rest of the number. This flag is ignored if "-"
* flag is specified.
*
* WIDTH:@n
* - Specify the minimal width of a printed argument. If it is bigger,
* width is ignored. If width is specified with a "*" character instead of
* number, width is taken from parameter list. And integer parameter is
* expected before parameter for processed conversion specification. If
* this value is negative its absolute value is taken and the "-" flag is
* set.
*
* PRECISION:@n
* - Value precision. For numbers it specifies minimum valid numbers.
* Smaller numbers are printed with leading zeroes. Bigger numbers are not
* affected. Strings with more than precision characters are cut off. Just
* as with width, an "*" can be used used instead of a number. An integer
* value is then expected in parameters. When both width and precision are
* specified using "*", the first parameter is used for width and the
* second one for precision.
*
* TYPE:@n
* - "hh" Signed or unsigned char.@n
* - "h" Signed or unsigned short.@n
* - "" Signed or unsigned int (default value).@n
* - "l" Signed or unsigned long int.@n
* If conversion is "c", the character is wchar_t (wide character).@n
* If conversion is "s", the string is wchar_t * (wide string).@n
* - "ll" Signed or unsigned long long int.@n
*
* CONVERSION:@n
* - % Print percentile character itself.
*
* - c Print single character. The character is expected to be plain
* ASCII (e.g. only values 0 .. 127 are valid).@n
* If type is "l", then the character is expected to be wide character
* (e.g. values 0 .. 0x10ffff are valid).
*
* - s Print zero terminated string. If a NULL value is passed as
* value, "(NULL)" is printed instead.@n
* If type is "l", then the string is expected to be wide string.
*
* - P, p Print value of a pointer. Void * value is expected and it is
* printed in hexadecimal notation with prefix (as with \%#X / \%#x
* for 32-bit or \%#X / \%#x for 64-bit long pointers).
*
* - b Print value as unsigned binary number. Prefix is not printed by
* default. (Nonstandard extension.)
*
* - o Print value as unsigned octal number. Prefix is not printed by
* default.
*
* - d, i Print signed decimal number. There is no difference between d
* and i conversion.
*
* - u Print unsigned decimal number.
*
* - X, x Print hexadecimal number with upper- or lower-case. Prefix is
* not printed by default.
*
* All other characters from fmt except the formatting directives are printed
* verbatim.
*
* @param fmt Format NULL-terminated string.
*
* @return Number of characters printed, negative value on failure.

/**
* @file
* @brief IRQ dispatcher.
*
* This file provides means of connecting IRQs with particular
* devices and logic for dispatching interrupts to IRQ handlers
* defined by those devices.
*
* This code is designed to support:
* - multiple devices sharing single IRQ
* - multiple IRQs per single device
* - multiple instances of the same device
*
*
* Note about architectures.
*
* Some architectures has the term IRQ well defined. Examples
* of such architectures include amd64, ia32 and mips32. Some
* other architectures, such as sparc64, don't use the term
* at all. In those cases, we boldly step forward and define what
* an IRQ is.
*
* The implementation is generic enough and still allows the
* architectures to use the hardware layout effectively.
* For instance, on amd64 and ia32, where there is only 16
* IRQs, the irq_hash_table can be optimized to a one-dimensional
* array. Next, when it is known that the IRQ numbers (aka INR's)
* are unique, the claim functions can always return IRQ_ACCEPT.
*
*
* Note about the irq_hash_table.
*
* The hash table is configured to use two keys: inr and devno.
* However, the hash index is computed only from inr. Moreover,
* if devno is -1, the match is based on the return value of
* the claim() function instead of on devno.

/**
* @file
* @brief Slab allocator.
*
* The slab allocator is closely modelled after OpenSolaris slab allocator.
* @see http://www.usenix.org/events/usenix01/full_papers/bonwick/bonwick_html/
*
* with the following exceptions:
* @li empty slabs are deallocated immediately
* (in Linux they are kept in linked list, in Solaris ???)
* @li empty magazines are deallocated when not needed
* (in Solaris they are held in linked list in slab cache)
*
* Following features are not currently supported but would be easy to do:
* @li cache coloring
* @li dynamic magazine growing (different magazine sizes are already
* supported, but we would need to adjust allocation strategy)
*
* The slab allocator supports per-CPU caches ('magazines') to facilitate
* good SMP scaling.
*
* When a new object is being allocated, it is first checked, if it is
* available in a CPU-bound magazine. If it is not found there, it is
* allocated from a CPU-shared slab - if a partially full one is found,
* it is used, otherwise a new one is allocated.
*
* When an object is being deallocated, it is put to a CPU-bound magazine.
* If there is no such magazine, a new one is allocated (if this fails,
* the object is deallocated into slab). If the magazine is full, it is
* put into cpu-shared list of magazines and a new one is allocated.
*
* The CPU-bound magazine is actually a pair of magazines in order to avoid
* thrashing when somebody is allocating/deallocating 1 item at the magazine
* size boundary. LIFO order is enforced, which should avoid fragmentation
* as much as possible.
*
* Every cache contains list of full slabs and list of partially full slabs.
* Empty slabs are immediately freed (thrashing will be avoided because
* of magazines).
*
* The slab information structure is kept inside the data area, if possible.
* The cache can be marked that it should not use magazines. This is used
* only for slab related caches to avoid deadlocks and infinite recursion
* (the slab allocator uses itself for allocating all it's control structures).
*
* The slab allocator allocates a lot of space and does not free it. When
* the frame allocator fails to allocate a frame, it calls slab_reclaim().
* It tries 'light reclaim' first, then brutal reclaim. The light reclaim
* releases slabs from cpu-shared magazine-list, until at least 1 slab
* is deallocated in each cache (this algorithm should probably change).
* The brutal reclaim removes all cached objects, even from CPU-bound
* magazines.
*
* @todo
* For better CPU-scaling the magazine allocation strategy should
* be extended. Currently, if the cache does not have magazine, it asks
* for non-cpu cached magazine cache to provide one. It might be feasible
* to add cpu-cached magazine cache (which would allocate it's magazines
* from non-cpu-cached mag. cache). This would provide a nice per-cpu
* buffer. The other possibility is to use the per-cache
* 'empty-magazine-list', which decreases competing for 1 per-system
* magazine cache.
*
* @todo
* it might be good to add granularity of locks even to slab level,
* we could then try_spinlock over all partial slabs and thus improve
* scalability even on slab level

Memory management
=================
1. Virtual Address Translation
1.1 Hierarchical 4-level per address space page tables
SPARTAN kernel deploys generic interface for 4-level page tables for these
architectures: amd64, arm32, ia32, mips32 and ppc32. In this setting, page
tables are hierarchical and are not shared by address spaces (i.e. one set of
page tables per address space).
VADDR
+-----------------------------------------------------------------------------+
| PTL0_INDEX | PTL1_INDEX | PTL2_INDEX | PTL3_INDEX | OFFSET |

PTL0 Page Table Level 0 (Page Directory)
PTL1 Page Table Level 1
PTL2 Page Table Level 2
PTL3 Page Table Level 3
PTL0_INDEX Index into PTL0
PTL1_INDEX Index into PTL1
PTL2_INDEX Index into PTL2
PTL3_INDEX Index into PTL3
VADDR Virtual address for which mapping is looked up
FRAME Physical address of memory frame to which VADDR is mapped
On architectures whose hardware has fewer levels, PTL2 and, if need be, PTL1 are
left out. TLB-only architectures are to define custom format for software page
tables.
1.2 Single global page hash table
Generic page hash table interface is deployed on 64-bit architectures without
implied hardware support for hierarchical page tables, i.e. ia64 and sparc64.
There is only one global page hash table in the system shared by all address
spaces.
2. Memory allocators
2.1 General allocator
'malloc' function accepts flags as a second argument. The flags are directly
passed to the underlying frame_alloc function.
1) If the flags parameter contains FRAME_ATOMIC, the allocator will not sleep.
The allocator CAN return NULL, when memory is not directly available.
The caller MUST check if NULL was not returned
2) If the flags parameter does not contain FRAME_ATOMIC, the allocator
will never return NULL, but it CAN sleep indefinitely. The caller
does not have to check the return value.
3) The maximum size that can be allocated using malloc is 256K
Rules 1) and 2) apply to slab_alloc as well. Using SLAB allocator
to allocate too large values is not recommended.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least

*
* This structure exists to help us to overcome certain limitations of the FAT
* file system design. The problem with FAT is that it is hard to find
* an entity which could represent a VFS index. There are two candidates:
*
* a) number of the node's first cluster
* b) the pair of the parent directory's first cluster and the dentry index
* within the parent directory
*
* We need VFS indices to be:
* A) unique
* B) stable in time, at least until the next mount
*
* Unfortunately a) does not meet the A) criterion because zero-length files
* will have the first cluster field cleared. And b) does not meet the B)
* criterion because unlink() and rename() will both free up the original
* dentry, which contains all the essential info about the file.
*
* Therefore, a completely opaque indices are used and the FAT server maintains
* a mapping between them and otherwise nice b) variant. On rename(), the VFS
* index stays unaltered, while the internal FAT "physical tree address"
* changes. The unlink case is also handled this way thanks to an in-core node
* pointer embedded in the index structure.

* The connection fibril accepts VFS requests from VFS. If there is only one
* instance of the fibril, VFS will need to serialize all VFS requests it sends
* to FAT. To overcome this bottleneck, VFS can send FAT the IPC_M_CONNECT_ME_TO
* call. In that case, a new connection fibril will be created, which in turn
* will accept the call. Thus, a new phone will be opened for VFS.
*
* There are few issues with this arrangement. First, VFS can run out of
* available phones. In that case, VFS can close some other phones or use one
* phone for more serialized requests. Similarily, FAT can refuse to duplicate
* the connection. VFS should then just make use of already existing phones and
* route its requests through them. To avoid paying the fibril creation price
* upon each request, FAT might want to keep the connections open after the
* request has been completed.

* This connection fibril processes VFS requests from VFS.

* In order to support simultaneous VFS requests, our design is as follows.
* The connection fibril accepts VFS requests from VFS. If there is only one
* instance of the fibril, VFS will need to serialize all VFS requests it sends
* to FAT. To overcome this bottleneck, VFS can send TMPFS the
* IPC_M_CONNECT_ME_TO call. In that case, a new connection fibril will be
* created, which in turn will accept the call. Thus, a new phone will be
* opened for VFS.
*
* There are few issues with this arrangement. First, VFS can run out of
* available phones. In that case, VFS can close some other phones or use one
* phone for more serialized requests. Similarily, TMPFS can refuse to duplicate
* the connection. VFS should then just make use of already existing phones and
* route its requests through them. To avoid paying the fibril creation price
* upon each request, TMPFS might want to keep the connections open after the
* request has been completed.

* @brief Generic scancode parser.
*
* The scancode parser is a simple finite state machine. It is described
* using sequences of input symbols (scancodes) and the corresponding output
* value (mods, key pair). When the parser recognizes a sequence,
* it outputs the value and restarts. If a transition is undefined,
* the parser restarts, too.
*
* Apart from precise values, GSP_DEFAULT allows to catch general cases.
* I.e. if we knew that after 0x1b 0x4f there always follow two more
* scancodes, we can define (0x1b, 0x4f, GSP_DEFAULT, GSP_DEFAULT, GSP_END)
* with null output. This will force the parser to read the entire sequence,
* not leaving garbage on the input if it does not recognize the specific
* sequence.

*
* OBIO is a short for on-board I/O. On UltraSPARC IIi and systems with U2P,
* there is a piece of the root PCI bus controller address space, which
* contains interrupt mapping and clear registers for all on-board devices.
* Although UltraSPARC IIi and U2P are different in general, these registers can
* be found at the same addresses.

*
* \% [ FLAGS ] [ WIDTH ] [ .PRECISION ] [ TYPE ] CONVERSION
*
* FLAGS:@n
* - "#" Force to print prefix. For \%o conversion, the prefix is 0, for
* \%x and \%X prefixes are 0x and 0X and for conversion \%b the
* prefix is 0b.
*
* - "-" Align to left.
*
* - "+" Print positive sign just as negative.
*
* - " " If the printed number is positive and "+" flag is not set,
* print space in place of sign.
*
* - "0" Print 0 as padding instead of spaces. Zeroes are placed between
* sign and the rest of the number. This flag is ignored if "-"
* flag is specified.
*
* WIDTH:@n
* - Specify the minimal width of a printed argument. If it is bigger,
* width is ignored. If width is specified with a "*" character instead of
* number, width is taken from parameter list. And integer parameter is
* expected before parameter for processed conversion specification. If
* this value is negative its absolute value is taken and the "-" flag is
* set.
*
* PRECISION:@n
* - Value precision. For numbers it specifies minimum valid numbers.
* Smaller numbers are printed with leading zeroes. Bigger numbers are not
* affected. Strings with more than precision characters are cut off. Just
* as with width, an "*" can be used used instead of a number. An integer
* value is then expected in parameters. When both width and precision are
* specified using "*", the first parameter is used for width and the
* second one for precision.
*
* TYPE:@n
* - "hh" Signed or unsigned char.@n
* - "h" Signed or unsigned short.@n
* - "" Signed or unsigned int (default value).@n
* - "l" Signed or unsigned long int.@n
* If conversion is "c", the character is wchar_t (wide character).@n
* If conversion is "s", the string is wchar_t * (wide string).@n
* - "ll" Signed or unsigned long long int.@n
*
* CONVERSION:@n
* - % Print percentile character itself.
*
* - c Print single character. The character is expected to be plain
* ASCII (e.g. only values 0 .. 127 are valid).@n
* If type is "l", then the character is expected to be wide character
* (e.g. values 0 .. 0x10ffff are valid).
*
* - s Print zero terminated string. If a NULL value is passed as
* value, "(NULL)" is printed instead.@n
* If type is "l", then the string is expected to be wide string.
*
* - P, p Print value of a pointer. Void * value is expected and it is
* printed in hexadecimal notation with prefix (as with \%#X / \%#x
* for 32-bit or \%#X / \%#x for 64-bit long pointers).
*
* - b Print value as unsigned binary number. Prefix is not printed by
* default. (Nonstandard extension.)
*
* - o Print value as unsigned octal number. Prefix is not printed by
* default.
*
* - d, i Print signed decimal number. There is no difference between d
* and i conversion.
*
* - u Print unsigned decimal number.
*
* - X, x Print hexadecimal number with upper- or lower-case. Prefix is
* not printed by default.
*
* All other characters from fmt except the formatting directives are printed
* verbatim.
*
* @param fmt Format NULL-terminated string.
*
* @return Number of characters printed, negative value on failure.

* Asynchronous library
*
* The aim of this library is to provide a facility for writing programs which
* utilize the asynchronous nature of HelenOS IPC, yet using a normal way of
* programming.
*
* You should be able to write very simple multithreaded programs, the async
* framework will automatically take care of most synchronization problems.
*
* Default semantics:
* - async_send_*(): Send asynchronously. If the kernel refuses to send
* more messages, [ try to get responses from kernel, if
* nothing found, might try synchronous ]
*
* Example of use (pseudo C):
*
* 1) Multithreaded client application
*
* fibril_create(fibril1, ...);
* fibril_create(fibril2, ...);
* ...
*
* int fibril1(void *arg)
* {
* conn = ipc_connect_me_to();
* c1 = async_send(conn);
* c2 = async_send(conn);
* async_wait_for(c1);
* async_wait_for(c2);
* ...
* }
*
*
* 2) Multithreaded server application
*
* main()
* {
* async_manager();
* }
*
* my_client_connection(icallid, *icall)
* {
* if (want_refuse) {
* ipc_answer_0(icallid, ELIMIT);
* return;
* }
* ipc_answer_0(icallid, EOK);

* Note about race conditions.
* Because of non-atomic nature of operations performed sequentially on the
* futex counter and the futex wait queue, there is a race condition:
*
* (wq->missed_wakeups == 1) && (futex->count = 1)
*
* Scenario 1 (wait queue timeout vs. futex_up()):
* 1. assume wq->missed_wakeups == 0 && futex->count == -1
* (ie. thread A sleeping, thread B in the critical section)
* 2. A receives timeout and gets removed from the wait queue
* 3. B wants to leave the critical section and calls futex_up()
* 4. B thus changes futex->count from -1 to 0
* 5. B has to call SYS_FUTEX_WAKEUP syscall to wake up the sleeping thread
* 6. B finds the wait queue empty and changes wq->missed_wakeups from 0 to 1
* 7. A fixes futex->count (i.e. the number of waiting threads) by changing it
* from 0 to 1
*
* Scenario 2 (conditional down operation vs. futex_up)
* 1. assume wq->missed_wakeups == 0 && futex->count == 0
* (i.e. thread A is in the critical section)
* 2. thread B performs futex_trydown() operation and changes futex->count from
* 0 to -1
* B is now obliged to call SYS_FUTEX_SLEEP syscall
* 3. A wants to leave the critical section and does futex_up()
* 4. A thus changes futex->count from -1 to 0 and must call SYS_FUTEX_WAKEUP
* syscall
* 5. B finds the wait queue empty and immediatelly aborts the conditional sleep
* 6. No thread is queueing in the wait queue so wq->missed_wakeups changes from
* 0 to 1
* 6. B fixes futex->count (i.e. the number of waiting threads) by changing it
* from 0 to 1
*
* Both scenarios allow two threads to be in the critical section
* simultaneously. One without kernel intervention and the other through
* wq->missed_wakeups being 1.
*
* To mitigate this problem, futex_down_timeout() detects that the syscall
* didn't sleep in the wait queue, fixes the futex counter and RETRIES the
* whole operation again.

Modules are commands or full programs (anything can be made into a module
that can return int type) should go here. Note, modules do not (can not)
update or read cliuser_t.
Stuff that needs to write to the user structures contained in scli.h should
be made as built-in commands, not modules, but there are very few times when
you would want to do that.
See the README file in the bdsh root directory for a quick overview of how to
write a new command, or convert an existig stand-alone program into a module
for BDSH.

Commands that need to modify the running user structure defined in scli.h
should reside here. They (will) have a slightly different prototype that
allows passing the user structure to them for ease of modifications.
Examples of what should be a built-in and not a module would be:
cd (cliuser_t->cwd needs to be updated)
In the future, more user preferences will be set via built-in commands,
such as the formatting of the prompt string (HelenOS doesn't yet have
an environment, much less PS*, even if it did we'd likely do it a little
differently).
.... etc.
Anything that does _not_ need to use this structure should be included
as a module, not a built in. If you want to include a new command, there
is a 99% chance that you want it to be a module.

\`$PROGNAME' generates skeletal command files to simplify adding commands
Usage: $PROGNAME [options] <location>
Options:
-n, --name Name of the command (default: ${def})
-d, --desc Short (20 30 chars) description of the command
(def: "The $def command")
-e, --entry Entry function of the command (def: cmd_${def})
-h, --help-entry Entry function for command help (def: help_cmd_${def})
-a, --alias Alias (nickname) for this command (def: none)
-t, --type Type of command (module or builtin) (def: module)
-H, --help This help summary
-V, --version Print $PROGNAME version and exit normally
Notes:
You must supply at least the name of the command.
If you do not specify a location (i.e. modules/foo), the command will be
created in modules/command_name or builtins/command_name depending on your
selection.
This script will only create skeletal files and inform you what headers
need to be modified to incorporate the command. You will also have to
manually update the main Makefile.
This script is intended only to be a convenience for developers. Example use:
$PROGNAME -n foo -d "Foo power" -a bar -r both -t module modules/foo
The example would generate a modular command named 'foo', which is also
reached by typing 'bar'.
Skeletal files do *not* depend on the autoconf generated "config.h" unless you
include it. This may or may not be desirable depending on your use.

BDSH - The Brain Dead Shell | Design Documentation
--------------------------------------------------
Overview:
=========
BDSH was written as a drop in command line interface for HelenOS to permit
interactive access to persistent file systems in development. BDSH was
written from scratch with a very limited userspace standard C library in
mind. Much like the popular Busybox program, BDSH provides a very limited
shell with limited common UNIX creature comforts built in.
Porting Busybox (and by extension ASH) would have taken much longer to
complete, much less make stable due to stark differences between Linux and
Spartan with regards to IPC, term I/O and process creation. BDSH was written
and made stable within the space of less than 30 days.
BDSH will eventually evolve and be refined into the HelenOS equivalent
of Busybox. While BDSH is now very intrinsic to HelenOS, its structure and
use of strictly lower level functions makes it extremely easy to port.
Design:
=======
BDSH is made up of three basic components:
1. Main i/o, error handling and task management
2. The builtin sub system
3. The module sub system
The main part handles user input, reports errors, spawns external tasks and
provides a convenient entry point for built-in and modular commands. A simple
structure, cliuser_t keeps track of the user's vitals, such as their current
working directory (and eventually uid, home directory, etc if they apply).
This part defines and exposes all functions that are not intrinsic to a
certain built in or modular command. For instance: string handlers,
module/builtin search and launch functions, error handlers and other things
can be found here.
Builtin commands are commands that must have access to cliuser_t, which is
not exposed to modular commands. For instance, the 'cd' command must update
the current working directory, which is stored in cliuser_t. As such, the
entry types for builtin commands are slightly different.
Modular commands do not need anything more than the basic functions that are
exposed by default. They do not need to modify cliuser_t, they are just self
contained. A modular command could very easily be made into a stand alone
program, likewise any stand alone program could easily become a modular
command.
Both modular and builtin commands share two things in common. Both must have
two entry points, one to invoke the command and one to invoke a help display
for the command. Exec (main()) entry points are int * and are expected to
return a value. Help entry points are void *, no return value is expected.
They are typed as such (from cmds.h):
/* Types for module command entry and help */
typedef int (* mod_entry_t)(char **);
typedef void (* mod_help_t)(unsigned int);
/* Built-in commands need to be able to modify cliuser_t */
typedef int (* builtin_entry_t)(char **, cliuser_t *);
typedef void (* builtin_help_t)(unsigned int);
As you can see, both modular and builtin commands expect an array of
arguments, however bulitins also expect to be pointed to cliuser_t.
Both are defined with the same simple structure:
/* Module structure */
typedef struct {
char *name; /* Name of the command */
char *desc; /* Description of the command */
mod_entry_t entry; /* Command (exec) entry function */
mod_help_t help; /* Command (help) entry function */
int restricted; /* Restricts to interactive/non-interactive only */
} module_t;
NOTE: Builtin commands may grow in this respect, that is why they are
defined separately.
Builtins, of course, would use the builtin_entry_t type. The name of the
command is used to associate user input to a possible entry point. The
description is a short (40 - 60 chars) summary of what the command does. Both
entry points are then defined, and the restrict value is used to determine a
commands availability.
Restriction levels are easy, a command is either available exclusively within
interactive mode, exclusively within non-interactive mode or both. If you are
looking at a prompt, you are in interactive mode. If you issue a command like
this:
/sbin/bdsh command [arg1] [arg2]
... you are in non interactive mode. This is done when you need to force the
parent shell to be the one who actually handles the command, or ensure that
/sbin/ls was used in lieu of the built in 'ls' when in non-interactive mode.
The values are:
0 : Unrestricted
-1 : Interactive only
1 : Non-interactive only
A script to generate skeletal files for a new command is included, it can be
found in cmds/mknewcmd. To generate a new modular command named 'foo', which
should also be reachable by typing 'f00', you would issue this command:
./mknewcmd -n foo -a f00 -t module
This generates all needed files and instructs you on how to include your new
command in the build and make it accessible. By default, the command will be
unrestricted. Builtin commands can be created by changing 'module' to
'builtin'
There are more options to mknewcmd, which allow you to specify the
description, entry point, help entry point, or restriction. By default, names
just follow the command such as cmd_foo(), help_cmd_foo(), 'The foo command',
etc. If you want to see the options and explanations in detail, use
./mknewcmd --help.
When working with commands, keep in mind that only the main and help entry
points need to be exposed. If commands share the same functions, put them
where they are exposed to all commands, without the potential oops of those
functions going away if the command is eliminated in favor of a stand alone
external program.
The util.c file is a great place to put those types of functions.
Also, be careful with globals, option structures, etc. The compiler will
generally tell you if you've made a mistake, however declaring:
volatile int foo
... in a command will allow for anything else to pick it up. Sometimes
this could be desirable .. other times not. When communicating between
builtins and the main system, try to use cliuser_t. The one exception
for this is the cli_quit global, since everything may at some point
need to check it. Modules should only communicate their return value.
Symbolic constants that everything needs should go in the config.h file,
however this is not the place to define shared macros.
Making a program into a module
==============================
If you have some neat program that would be useful as a modular command,
converting it is not very hard. The following steps should get you through
the process easily (assuming your program is named 'foo'):
1: Use mknewcmd to generate the skeletal files.
2: Change your "usage()" command as shown:
-- void usage(...)
++ void help_cmd_foo(unsigned int level)
'level' is either 0 or 1, indicating the level of help requested.
If the help / usage function currently exits based on how it is
called, you'll need to change it.
3: Change the programs "main()" as shown:
-- int main(int argc, char **argv)
++ int cmd_foo(char **argv)
-- return 1;
++ return CMD_FAILURE;
-- return 0;
++ return CMD_SUCCESS;
NOTE: If main is void, you'll need to change it and ensure that its
expecting an array of arguments, even if they'll never be read or
used. I.e.:
-- void main(void)
++ int cmd_foo(char **argv)
4: Don't expose more than the entry and help points:
-- void my_function(int n)
++ static void my_function(int n)
5: Copy/paste to the stub generated by mknewcmd then add your files to the
Makefile. Be sure to add any directories that you made to the SUBDIRS so
that a 'make clean' will clean them.
Provided that all functions that your calling are available in the
userspace C library, your program should compile just fine and appear
as a modular command.
Overcoming userspace libc obstacles
===================================
A quick glance through the util.c file will reveal functions like
cli_strdup(), cli_strtok(), cli_strtok_r() and more. Those are functions
that were missing from userspace libc when BDSH was born. Later, after
porting what was needed from FBSD/NBSD, the real functions appeared in
the userspace libc after being tested in their cli_* implementations.
Those functions remain because they guarantee that bdsh will work even
on systems that lack them. Additionally, more BDSH specific stuff can
go into them, such as error handling and reporting when malloc() fails.
You will also notice that FILE, fopen() (and all friends), ato*() and
other common things might be missing. The HelenOS userspace C library is
still very young, you are sure to run into something that you want/need
which is missing.
When that happens, you have three options:
1 - Implement it internally in util.c , when its tested and stable send a
patch to HelenOS asking for your function to be included in libc. This is
the best option, as you not only improve BDSH .. but HelenOS as a whole.
2 - Work around it. Not everyone can implement / port fopen() and all of
its friends. Make open(), read(), write() (etc) work if at all possible.
3 - Send an e-mail to the HelenOS development mailing list. Explain why you
need the function and what its absence is holding up.
If what you need is part of a library that is typically a shared object, try
to implement a 'mini' version of it. Currently, all userspace applications
are statically linked. Giving up creature comforts for size while avoiding
temporary 'band aids' is never frowned upon.
Most of all, don't get discouraged .. ask for some help prior to giving up
if you just can't accomplish something with the limited means provided.
Contributing
============
I will take any well written patch that sanely improves or expands BDSH. Send
me a patch against the trunk revision, or, if you like a Mercurial repository
is also maintained at http://echoreply.us/hg/bdsh.hg and kept in sync with
the trunk.
Please be sure to follow the simple coding standards outlined at
http://www.helenos.eu/cstyle (mostly just regarding formatting), test your
changes and make sure your patch applies cleanly against the latest revision.
All patches submitted must be your original code, or a derivative work of
something licensed under the same 3 clause BSD license as BDSH. See LICENSE
for more information.
When sending patches, you agree that your work will be published under the
same 3 clause BSD license as BDSH itself. Failure to ensure that anything
you used is not under the same or less restrictive license could cause major
issues for BDSH in the future .. please be sure. Also, please don't forget
to add yourself in the AUTHORS file, as I am horrible about keeping such
things up to date.

This is a very brain dead shell. It needs some love, coffee or perhaps beer.
Currently, you can't even really call it a shell, its more of a CLI that
offers some shell like creature comforts.
This was written in a hurry to provide some means of testing persistent file
systems in HelenOS. It does its job, its nowhere near complete but it is
actively developed. If your reading this, its likely that you're looking for
some functionality that is not yet present. Prior to filing a bug report,
please make sure that what you want is not on the list below.
A list of things to do:
-----------------------
* rm: add support for recursively removing directories and files therein
* Port an editor (vim?)
* Finish cat / cp
* Support basic redirection (i.e ls > foo.txt)
* Expand wildcards (i.e. *.txt), don't worry about variables for now
* Basic scripting
* Hash previously found commands
* Improve input, add history / etc (port libedit?)
* Add wrappers for signal, sigaction to make ports to modules easier
* Add 'echo' and 'printf' modules.
Regarding POSIX:
----------------
POSIX is a standard for Unix-like operating systems. HelenOS is (mostly) just
a kernel at this point with a few userspace programs that facilitate testing
of the kernel and file systems.
HelenOS is not a Unix-like operating system. HelenOS is its own thing, a modern
microkernel OS and many directions are not yet set.
Please do not e-mail me to point out that modular implementations that resemble
typical core utilities do not conform to some POSIX standard, these are temporary
and serve the useful purpose of testing persistent file systems.
Contributing:
-------------
If you feel like doing any of the above to-do items, I am echo@echoreply.us. Please
e-mail me and let me know your working on something so that I do not unwittingly
duplicate your efforts. You can also e-mail the HelenOS list directly:
HelenOS development mailing list <helenos-devel@lists.modry.cz>
Subscribe here if you like: http://lists.modry.cz/cgi-bin/listinfo/helenos-devel
Cheers and happy hacking!

* A `shape' is the fundamental thing that makes up the game. There

*
* X.X X.X X.X
* X.X X.X X.X.X X.X X.X.X X.X.X X.X.X.X
* X X X
*
* 0 1 2 3 4 5 6
*
* Except for 3 and 6, the center of each shape is one of the blots.
* This blot is designated (0, 0). The other three blots can then be
* described as offsets from the center. Shape 3 is the same under
* rotation, so its center is effectively irrelevant; it has been chosen
* so that it `sticks out' upward and leftward. Except for shape 6,
* all the blots are contained in a box going from (-1, -1) to (+1, +1);
* shape 6's center `wobbles' as it rotates, so that while it `sticks out'
* rightward, its rotation---a vertical line---`sticks out' downward.
* The containment box has to include the offset (2, 0), making the overall
* containment box range from offset (-1, -1) to (+2, +1). (This is why
* there is only one row above, but two rows below, the display area.)
*
* The game works by choosing one of these shapes at random and putting
* its center at the middle of the first display row (row 1, column 5).
* The shape is moved steadily downward until it collides with something:
* either another shape, or the bottom of the board. When the shape can
* no longer be moved downwards, it is merged into the current board.
* At this time, any completely filled rows are elided, and blots above
* these rows move down to make more room. A new random shape is again
* introduced at the top of the board, and the whole process repeats.
* The game ends when the new shape will not fit at (1, 5).
*
* While the shapes are falling, the user can rotate them counterclockwise
* 90 degrees (in addition to moving them left or right), provided that the
* rotation puts the blots in empty spaces. The table of shapes is set up
* so that each shape contains the index of the new shape obtained by
* rotating the current shape. Due to symmetry, each shape has exactly
* 1, 2, or 4 rotations total; the first 7 entries in the table represent
* the primary shapes, and the remaining 12 represent their various

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

IMPORTANT information related to the gnu-efi package
----------------------------------------------------
June 2001
As of version 3.0, the gnu-efi package is now split in two different packages:
-> gnu-efi-X.y: contains the EFI library, include files and crt0.
-> elilo-X.y : contains the ELILO bootloader.
Note that X.y don't need to match for both packages. However elilo-3.x
requires at least gnu-efi-3.0.
Both packages can be downloaded from:
ftp://ftp.hpl.hp.com/pub/linux-ia64/gnu-efi-X.y.tar.gz
http://www.sf.net/projects/elilo

Abstract:
EFI Hell to remap runtime address into the new virual address space
that was registered by the OS for RT calls.
So the code image needs to be relocated. All pointers need to be
manually fixed up since the address map changes.
GOOD LUCK NOT HAVING BUGS IN YOUR CODE! PLEASE TEST A LOT. MAKE SURE

0,0 → 1,193
2006-03-21 Stephane Eranian <eranian@hpl.hp.com>
* merged patch to support gcc-4.1 submitted by
Raymund Will from Novell/SuSE
2006-03-20 Stephane Eranian <eranian@hpl.hp.com>
* updated ia-64 and ia-32 linker scripts to
match latest gcc. The new gcc may put functions in
.text* sections. patch submitted by H.J. Lu from Intel.
2004-11-19 Stephane Eranian <eranian@hpl.hp.com>
* added patch to ignore .eh_frame section for IA-32. Patch
submitted by Jim Wilson
2004-09-23 Stephane Eranian <eranian@hpl.hp.com>
* added patch to discard unwind sections, newer toolchains
complained about them. Patch submitted by Jesse Barnes from SGI.
2003-09-29 Stephane Eranian <eranian@hpl.hp.com>
* updated elf_ia64_efi.lds to reflect new data sections
created by gcc-3.3. Patch provided by Andreas Schwab from Suse.
2003-06-20 Stephane Eranian <eranian@hpl.hp.com>
* updated elf_ia64_efi.lds and elf_ia32_efi.lds to include
new types data sections produced by recent version of gcc-3.x
2002-02-22 Stephane Eranian <eranian@hpl.hp.com>
* release 3.0a
* modified both IA-64 and IA-32 loader scripts to add support for the
new .rodata sections names (such as rodata.str2.8). Required
for new versions of gcc3.x.
2001-06-20 Stephane Eranian <eranian@hpl.hp.com>
* release 3.0
* split gnu-efi package in two different packages: the libary+include+crt and the bootloader.
* removed W2U() hack and related files to get from wide-char to unicode.
* Use -fshort-wchar option for unicode.
* restructured Makefiles now install under INSTALLROOT.
2001-04-06 Stephane Eranian <eranian@hpl.hp.com>
* incorporated patches from David and Michael Johnston at Intel
to get the package to compile for IA-32 linux target.
* Fixed ELILO to compile for Ia-32 (does not execute yet, though):
Makefile and start_kernel() function.
2001-04-06 Andreas Schwab <schwab@suse.de>
* Fixed config.c to
get the timeout directive to do something. implemented the global
root= directive.
* Fix the efi_main() to deal with the -C option properly
2001-04-05 Stephane Eranian <eranian@hpl.hp.com>
* update efi library to latest EFI toolkit 1.02 as distributed
by Intel. Fixed header + library files to compile with GCC
* merged ELI and LILO (as of gnu-efi-1.1) together, mostly
taking the config file feature of ELI.
* renamed LILO to ELILO to make the distinction
* restructured code to make it easier to understand and maintain
* fixed FPSWA driver checking and loading: we try all possible
files and let the driver itself figure out if it is the most
recent.
* added support for compression (gzip) but keep support for plain
ELF image. ELILO autodetects the format
* change the way the kernel is invoked. Now we call it in
physical memory mode. This breaks the dependency between the
kernel code and the loader. No more lilo_start.c madness.
* changed the way the boot_params are passed. We don't use the
ZERO_PAGE_ADDR trick anymore. Instead we use EFI runtime memory.
The address of the structure is passed to the kernel in r28
by our convention.
* released as gnu-efi-2.0
2001-04-03 David Mosberger <davidm@hpl.hp.com>
* gnuefi/reloc_ia32.c (_relocate): Change return type from "void"
to "int". Return error status if relocation fails for some
reason.
* gnuefi/elf_ia32_efi.lds: Drop unneeded ".rel.reloc" section.
* gnuefi/crt0-efi-ia32.S (_start): Exit if _relocate() returns with
non-zero exit status.
* inc/ia32/efibind.h [__GNUC__]: Force 8-byte alignment for 64-bit
types as that is what EFI appears to be expecting, despite the
"#pragma pack()" at the beginning of the file!
2001-03-29 David Mosberger <davidm@hpl.hp.com>
* gnuefi/reloc_ia32.c: Add a couple of defines to work around
libc/efilib collision on uint64_t et al.
(_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().
* gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.
2001-03-29 David Mosberger <davidm@hpl.hp.com>
* gnuefi/reloc_ia32.c: Add a couple of defines to work around
libc/efilib collision on uint64_t et al.
(_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().
* gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.
2000-10-26 David Mosberger <davidm@hpl.hp.com>
* gnuefi/elf_ia64_efi.lds: Mention .rela.sdata.
* Make.defaults (CFLAGS): Remove -nostdinc flags so we can pick
up the C compiler's stdarg.h.
* inc/stdarg.h: Remove this file. It's not correct for gcc (nor
most other optimizing compilers).
2000-10-10 Stephane Eranian <eranian@hpl.hp.com>
* cleaned up the error message and printing of those.
* added support to load the FPSWA from a file in case support is not
present in the firmware already
* fixed split_args() to do the right thing when you have leading spaces
before kernel name
* changed the argify() function to rely on \0 instead of LoadOptionSize

Building EFI Applications Using the GNU Toolchain

* Introduction
This document has two parts: the first part describes how to develop
EFI applications for IA-64 and x86 using the GNU toolchain and the EFI
development environment contained in this directory. The second part
describes some of the more subtle aspects of how this development
environment works.
* Part 1: Developing EFI Applications
** Prerequisites:
To develop x86 EFI applications, the following tools are needed:
- gcc-3.0 or newer (gcc 2.7.2 is NOT sufficient!)
As of gnu-efi-3.0b, the Redhat 8.0 toolchain is known to work,
but the Redhat 9.0 toolchain is not currently supported.
- A version of "objcopy" that supports EFI applications. To
check if your version includes EFI support, issue the
command:
objcopy --help
and verify that the line "supported targets" contains the
string "efi-app-ia32".
- For debugging purposes, it's useful to have a version of
"objdump" that supports EFI applications as well. This
allows inspect and disassemble EFI binaries.
To develop IA-64 EFI applications, the following tools are needed:
- A version of gcc newer than July 30th 1999 (older versions
had problems with generating position independent code).
As of gnu-efi-3.0b, gcc-3.1 is known to work well.
- A version of "objcopy" that supports EFI applications. To
check if your version includes EFI support, issue the
command:
objcopy --help
and verify that the line "supported targets" contains the
string "efi-app-ia64".
- For debugging purposes, it's useful to have a version of
"objdump" that supports EFI applications as well. This
allows inspect and disassemble EFI binaries.
** Directory Structure
This EFI development environment contains the following
subdirectories:
inc: This directory contains the EFI-related include files. The
files are taken from Intel's EFI source distribution, except
that various fixes were applied to make it compile with the
GNU toolchain.
lib: This directory contains the source code for Intel's EFI library.
Again, the files are taken from Intel's EFI source
distribution, with changes to make them compile with the GNU
toolchain.
gnuefi: This directory contains the glue necessary to convert ELF64
binaries to EFI binaries. Various runtime code bits, such as
a self-relocator are included as well. This code has been
contributed by the Hewlett-Packard Company and is distributed
under the GNU GPL.
apps: This directory contains a few simple EFI test apps.
** Setup
It is necessary to edit the Makefile in the directory containing this
README file before EFI applications can be built. Specifically, you
should verify that macros CC, AS, LD, AR, RANLIB, and OBJCOPY point to
the appropriate compiler, assembler, linker, ar, and ranlib binaries,
respectively.
If you're working in a cross-development environment, be sure to set
macro ARCH to the desired target architecture ("ia32" for x86, "ia64"
for IA-64). For convenience, this can also be done from the make
command line (e.g., "make ARCH=ia64").
** Building
To build the sample EFI applications provided in subdirectory "apps",
simply invoke "make" in the toplevel directory (the directory
containing this README file). This should build lib/libefi.a and
gnuefi/libgnuefi.a first and then all the EFI applications such as a
apps/t6.efi.
** Running
Just copy the EFI application (e.g., apps/t6.efi) to the EFI
filesystem, boot EFI, and then select "Invoke EFI application" to run
the application you want to test. Alternatively, you can invoke the
Intel-provided "nshell" application and then invoke your test binary
via the command line interface that "nshell" provides.
** Writing Your Own EFI Application
Suppose you have your own EFI application in a file called
"apps/myefiapp.c". To get this application built by the GNU EFI build
environment, simply add "myefiapp.efi" to macro TARGETS in
apps/Makefile. Once this is done, invoke "make" in the top level
directory. This should result in EFI application apps/myefiapp.efi,
ready for execution.
The GNU EFI build environment allows to write EFI applications as
described in Intel's EFI documentation, except for two differences:
- The EFI application's entry point is always called "efi_main". The
declaration of this routine is:
EFI_STATUS efi_main (EFI_HANDLE image, EFI_SYSTEM_TABLE *systab);
- UNICODE string literals must be written as W2U(L"Sample String")
instead of just L"Sample String". The W2U() macro is defined in
<efilib.h>. This header file also declares the function W2UCpy()
which allows to convert a wide string into a UNICODE string and
store the result in a programmer-supplied buffer.
* Part 2: Inner Workings
WARNING: This part contains all the gory detail of how the GNU EFI
toolchain works. Normal users do not have to worry about such
details. Reading this part incurs a definite risk of inducing severe
headaches or other maladies.
The basic idea behind the GNU EFI build environment is to use the GNU
toolchain to build a normal ELF binary that, at the end, is converted
to an EFI binary. EFI binaries are really just PE32+ binaries. PE
stands for "Portable Executable" and is the object file format
Microsoft is using on its Windows platforms. PE is basically the COFF
object file format with an MS-DOS2.0 compatible header slapped on in
front of it. The "32" in PE32+ stands for 32 bits, meaning that PE32
is a 32-bit object file format. The plus in "PE32+" indicates that
this format has been hacked to allow loading a 4GB binary anywhere in
a 64-bit address space (unlike ELF64, however, this is not a full
64-bit object file format because the entire binary cannot span more
than 4GB of address space). EFI binaries are plain PE32+ binaries
except that the "subsystem id" differs from normal Windows binaries.
There are two flavors of EFI binaries: "applications" and "drivers"
and each has there own subsystem id and are identical otherwise. At
present, the GNU EFI build environment supports the building of EFI
applications only, though it would be trivial to generate drivers, as
the only difference is the subsystem id. For more details on PE32+,
see the spec at
http://msdn.microsoft.com/library/specs/msdn_pecoff.htm.
In theory, converting a suitable ELF64 binary to PE32+ is easy and
could be accomplished with the "objcopy" utility by specifying option
--target=efi-app-ia32 (x86) or --target=efi-app-ia64 (IA-64). But
life never is that easy, so here some complicating factors:
(1) COFF sections are very different from ELF sections.
ELF binaries distinguish between program headers and sections.
The program headers describe the memory segments that need to
be loaded/initialized, whereas the sections describe what
constitutes those segments. In COFF (and therefore PE32+) no
such distinction is made. Thus, COFF sections need to be page
aligned and have a size that is a multiple of the page size
(4KB for EFI), whereas ELF allows sections at arbitrary
addresses and with arbitrary sizes.
(2) EFI binaries should be relocatable.
Since EFI binaries are executed in physical mode, EFI cannot
guarantee that a given binary can be loaded at its preferred
address. EFI does _try_ to load a binary at it's preferred
address, but if it can't do so, it will load it at another
address and then relocate the binary using the contents of the
.reloc section.
(3) On IA-64, the EFI entry point needs to point to a function
descriptor, not to the code address of the entry point.
(4) The EFI specification assumes that wide characters use UNICODE
encoding.
ANSI C does not specify the size or encoding that a wide
character uses. These choices are "implementation defined".
On most UNIX systems, the GNU toolchain uses a wchar_t that is
4 bytes in size. The encoding used for such characters is
(mostly) UCS4.
In the following sections, we address how the GNU EFI build
environment addresses each of these issues.
** (1) Accommodating COFF Sections
In order to satisfy the COFF constraint of page-sized and page-aligned
sections, the GNU EFI build environment uses the special linker script
in gnuefi/elf_$(ARCH)_efi.lds where $(ARCH) is the target architecture
("ia32" for x86, and "ia64" for IA-64). This script is set up to
create only eight COFF section, each page aligned and page sized.
These eight sections are used to group together the much greater
number of sections that are typically present in ELF object files.
Specifically:
.hash
Collects the ELF .hash info (this section _must_ be the first
section in order to build a shared object file; the section is
not actually loaded or used at runtime).
.text
Collects all sections containing executable code.
.data
Collects read-only and read-write data, literal string data,
global offset tables, the uninitialized data segment (bss) and
various other sections containing data.
The reason read-only data is placed here instead of the in
.text is to make it possible to disassemble the .text section
without getting garbage due to read-only data. Besides, since
EFI binaries execute in physical mode, differences in page
protection do not matter.
The reason the uninitialized data is placed in this section is
that the EFI loader appears to be unable to handle sections
that are allocated but not loaded from the binary.
.dynamic, .dynsym, .rela, .rel, .reloc
These sections contains the dynamic information necessary to
self-relocate the binary (see below).
A couple of more points worth noting about the linker script:
o On IA-64, the global pointer symbol (__gp) needs to be placed such
that the _entire_ EFI binary can be addressed using the signed
22-bit offset that the "addl" instruction affords. Specifically,
this means that __gp should be placed at ImageBase + 0x200000.
Strictly speaking, only a couple of symbols need to be addressable
in this fashion, so with some care it should be possible to build
binaries much larger than 4MB. To get a list of symbols that need
to be addressable in this fashion, grep the assembly files in
directory gnuefi for the string "@gprel".
o The link address (ImageBase) of the binary is (arbitrarily) set to
zero. This could be set to something larger to increase the chance
of EFI being able to load the binary without requiring relocation.
However, a start address of 0 makes debugging a wee bit easier
(great for those of us who can add, but not subtract... ;-).
o The relocation related sections (.dynamic, .rel, .rela, .reloc)
cannot be placed inside .data because some tools in the GNU
toolchain rely on the existence of these sections.
o Some sections in the ELF binary intentionally get dropped when
building the EFI binary. Particularly noteworthy are the dynamic
relocation sections for the .plabel and .reloc sections. It would
be _wrong_ to include these sections in the EFI binary because it
would result in .reloc and .plabel being relocated twice (once by
the EFI loader and once by the self-relocator; see below for a
description of the latter). Specifically, only the sections
mentioned with the -j option in the final "objcopy" command are
retained in the EFI binary (see apps/Makefile).
** (2) Building Relocatable Binaries
ELF binaries are normally linked for a fixed load address and are thus
not relocatable. The only kind of ELF object that is relocatable are
shared objects ("shared libraries"). However, even those objects are
usually not completely position independent and therefore require
runtime relocation by the dynamic loader. For example, IA-64 binaries
normally require relocation of the global offset table.
The approach to building relocatable binaries in the GNU EFI build
environment is to:
(a) build an ELF shared object
(b) link it together with a self-relocator that takes care of
applying the dynamic relocations that may be present in the
ELF shared object
(c) convert the resulting image to an EFI binary
The self-relocator is of course architecture dependent. The x86
version can be found in gnuefi/reloc_ia32.c, the IA-64 version can be
found in gnuefi/reloc_ia64.S.
The self-relocator operates as follows: the startup code invokes it
right after EFI has handed off control to the EFI binary at symbol
"_start". Upon activation, the self-relocator searches the .dynamic
section (whose starting address is given by symbol _DYNAMIC) for the
dynamic relocation information, which can be found in the DT_REL,
DT_RELSZ, and DT_RELENT entries of the dynamic table (DT_RELA,
DT_RELASZ, and DT_RELAENT in the case of rela relocations, as is the
case for IA-64). The dynamic relocation information points to the ELF
relocation table. Once this table is found, the self-relocator walks
through it, applying each relocation one by one. Since the EFI
binaries are fully resolved shared objects, only a subset of all
possible relocations need to be supported. Specifically, on x86 only
the R_386_RELATIVE relocation is needed. On IA-64, the relocations
R_IA64_DIR64LSB, R_IA64_REL64LSB, and R_IA64_FPTR64LSB are needed.
Note that the R_IA64_FPTR64LSB relocation requires access to the
dynamic symbol table. This is why the .dynsym section is included in
the EFI binary. Another complication is that this relocation requires
memory to hold the function descriptors (aka "procedure labels" or
"plabels"). Each function descriptor uses 16 bytes of memory. The
IA-64 self-relocator currently reserves a static memory area that can
hold 100 of these descriptors. If the self-relocator runs out of
space, it causes the EFI binary to fail with error code 5
(EFI_BUFFER_TOO_SMALL). When this happens, the manifest constant
MAX_FUNCTION_DESCRIPTORS in gnuefi/reloc_ia64.S should be increased
and the application recompiled. An easy way to count the number of
function descriptors required by an EFI application is to run the
command:
objdump --dynamic-reloc example.so | fgrep FPTR64 | wc -l
assuming "example" is the name of the desired EFI application.
** (3) Creating the Function Descriptor for the IA-64 EFI Binaries
As mentioned above, the IA-64 PE32+ format assumes that the entry
point of the binary is a function descriptor. A function descriptors
consists of two double words: the first one is the code entry point
and the second is the global pointer that should be loaded before
calling the entry point. Since the ELF toolchain doesn't know how to
generate a function descriptor for the entry point, the startup code
in gnuefi/crt0-efi-ia64.S crafts one manually by with the code:
.section .plabel, "a"
_start_plabel:
data8 _start
data8 __gp
this places the procedure label for entry point _start in a section
called ".plabel". Now, the only problem is that _start and __gp need
to be relocated _before_ EFI hands control over to the EFI binary.
Fortunately, PE32+ defines a section called ".reloc" that can achieve
this. Thus, in addition to manually crafting the function descriptor,
the startup code also crafts a ".reloc" section that has will cause
the EFI loader to relocate the function descriptor before handing over
control to the EFI binary (again, see the PECOFF spec mentioned above
for details).
A final question may be why .plabel and .reloc need to go in their own
COFF sections. The answer is simply: we need to be able to discard
the relocation entries that are generated for these sections. By
placing them in these sections, the relocations end up in sections
".rela.plabel" and ".rela.reloc" which makes it easy to filter them
out in the filter script. Also, the ".reloc" section needs to be in
its own section so that the objcopy program can recognize it and can
create the correct directory entries in the PE32+ binary.
** (4) Convenient and Portable Generation of UNICODE String Literals
As of gnu-efi-3.0, we make use (and somewhat abuse) the gcc option
that forces wide characters (WCHAR_T) to use short integers (2 bytes)
instead of integers (4 bytes). This way we match the Unicode character
size. By abuse, we mean that we rely on the fact that the regular ASCII
characters are encoded the same way between (short) wide characters
and Unicode and basically only use the first byte. This allows us
to just use them interchangeably.
The gcc option to force short wide characters is : -fshort-wchar

Abstract:
Protocol used to build User Interface (UI) stuff.
This protocol is just data. It is a multi dimentional array.
For each string there is an array of UI_STRING_ENTRY. Each string
is for a different language translation of the same string. The list
is terminated by a NULL UiString. There can be any number of
UI_STRING_ENTRY arrays. A NULL array terminates the list. A NULL array
entry contains all zeros.
Thus the shortest possible EFI_UI_PROTOCOL has three UI_STRING_ENTRY.
The String, it's NULL terminator, and the NULL terminator for the entire
thing.

// ClearStore() - A function to clear the requested storage bank. A cleared
// bank contains all "on" bits.
//
// ReadStore() - Read data from the requested store.
//
// UpdateStore() - Updates data on the requested store. The FW will only
// ever issue updates to clear bits in the store. Updates must be
// performed in LSb to MSb order of the update buffer.
//
// SizeStore() - An optional function for non-runtime stores that can be
// dynamically sized. The FW will only ever increase or decrease the store
// by 1 banksize at a time, and it is always adding or removing a bank from
// the end of the store.
//
// By default the FW will update variables and storage banks in an
// "atomic" manner by keeping 1 old copy of the data during an update,
// and recovering appropiately if the power is lost during the middle
// of an operation. To do this the FW needs to have multiple banks
// of storage dedicated to its use. If that's not possible, the driver
// can implement an atomic bank update function and the FW will allow
// 1 bank in this case. (It will allow any number of banks,
// but it won't require an "extra" bank to provide its bank transaction
// function).
//
// TransactionUpdate() - An optional function that can clear & update an
// entire bank in an "atomic" fashion. If the operation fails in the
// middle the driver is responsible for having either the previous copy
// of the bank's data or the new copy. A copy that's partially written
// is not valid as internal data settings may get lost. Supply this
// function only when needed.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.
