2782 5901 d 22 h jermar /tags/0.3.0/ Tagging HelenOS 0.3.0.  
2765 5910 d 23 h jermar /trunk/kernel/generic/src/proc/ tasklet.c needs to include config.h  
2746 5922 d 2 h decky /trunk/kernel/ start merging tasklets (more or less a rewrite)  
2745 5922 d 7 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5943 d 4 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2724 5943 d 5 h decky /trunk/kernel/generic/src/interrupt/ enlarge description field  
2721 5944 d 5 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2712 5948 d 4 h decky /trunk/kernel/ prettyprint output  
2701 5955 d 7 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2697 5965 d 5 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2684 5973 d 23 h jermar /trunk/ Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized).		  
2677 5980 d 2 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.		  
2676 5980 d 8 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.		  
2662 5987 d 21 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2661 5987 d 22 h jermar /trunk/kernel/generic/src/ipc/ Release the IPC_M_DATA_WRITE buffer even if the write is refused by the
recipient.		  
2660 5987 d 23 h jermar /trunk/ Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver().		  
2647 5995 d 0 h jermar /trunk/kernel/generic/src/mm/ Fix a bug in anonymous address space area sharing. Call the backend's share
function only if the source area is not already shared. Otherwise increment the
sh_info refcount. Without this fix, the kernel will try to recreate the pagemap
if three and more address space areas attempt to share the same data.		  
2646 5995 d 0 h jermar /trunk/kernel/generic/include/ Formatting.  
2638 6006 d 22 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6006 d 23 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2636 6008 d 22 h jermar /trunk/ Update comments wrt the previous commit.
Minor formatting fixes.		  
2635 6008 d 23 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.		  
2632 6009 d 18 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2626 6016 d 9 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2623 6017 d 4 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6017 d 4 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2620 6019 d 9 h jermar /trunk/ Be more deterministic when a user accidently uses fast version of IPC
call/answer instead of the full one and passes fewer arguments than required by
the recipient of the call/response.

and the recipient interprets arguments that
were actually not passed by the sender.		  
2619 6020 d 21 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2618 6021 d 9 h jermar /trunk/ Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async.		  
2617 6022 d 2 h jermar /trunk/kernel/generic/src/ipc/ STRUCT_TO_USPACE may fail in sys_ipc_call_sync_fast.  
2615 6022 d 6 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.		  
2614 6023 d 4 h jermar /trunk/kernel/generic/include/ipc/ Grow the IPC data structures from 3 to 5 payload arguments.
No IPC API changes so far.		  
2605 6025 d 2 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2601 6030 d 1 h jermar /trunk/kernel/generic/src/ipc/ Fix and improve two IPC related comments.  
2574 6045 d 23 h jermar /trunk/kernel/generic/src/lib/ Fix elf.c's formatting and add code that can be later enhanced and used to
remember task's TLS section alignment, address and size.		  
2573 6049 d 0 h jermar /trunk/kernel/generic/include/lib/ Add SHF_TLS ELF section header flag.
This will be needed for detecting alignment of TLS sections of userspace tasks
loaded at runtime.		  
2572 6067 d 13 h jermar /trunk/kernel/ Remove duplicit implementation of strlen() in kernel, rename is_digit(),
is_white() and co. to their standard names (e.g. isdigit(), isspace()) and
remove duplicit implementation of isdigit(). Fix cstyle in kernel printf()
implementation.		  
2571 6068 d 4 h jermar /trunk/kernel/generic/src/printf/ Fix the string printing precision bug also in the kernel.  
2557 6073 d 6 h jermar /trunk/kernel/generic/src/ipc/ Enable forwarding of IPC_M_AS_AREA_SEND, IPC_M_AS_AREA_RECV, IPC_M_DATA_SEND
calls. In order to prevent the forwarder from cloberring the call data (i.e.
source and destination address, and size) by treating these three methods as
immutable on forward. This feature is experimental, but has huge benefits in
that it can significantly reduce the amount of data sharing (the middle man need
not modify its address space mappings) or the amount of data copying (the middle
man need not receive the data from the sender and then resend them to the next
recipient). As a result, it can reduce N such calls for a communication channel
with N tasks along the way to 1 such call.		  
2556 6073 d 8 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.
