2618 6194 d 11 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.

2615 6195 d 8 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.

2574 6219 d 1 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.
 
/trunk/kernel/generic/src/lib/elf.c
2573 6222 d 2 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.
 
/trunk/kernel/generic/include/lib/elf.h
2572 6240 d 15 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.

2557 6246 d 8 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.

2527 6259 d 10 h jermar /trunk/ VFS work.

Added mandatory VFS_LOOKUP

Handling of VFS_REGISTER request should be now more or less complete.
Added code that inserts the new fs_info structure into the list of registered
filesystems and creates a callback connection to the client FS.

2523 6260 d 12 h jermar /trunk/ VFS work.

Now, each VFS connection fibril will accept requests in a loop. The idea is that
each connection will be potentially reused for multiple requests before it is
closed by the server.

More VFS_REGISTER bits. Make use of the IPC_M_DATA_SEND wrappers introduced in
the previous commit.

Add enum members for more VFS operations.

2504 6308 d 1 h jermar /trunk/kernel/generic/ Give the AVL tree walkers the possibility to take an argument.
Each walker is now supposed to return a bool value to support walk termination.

Switch over from the tasks_btree B+tree to tasks_tree AVL tree.
This makes the fix for ticket #48 complete.

2502 6308 d 7 h jermar /trunk/kernel/generic/ Replace the threads_btree B+tree with an AVL tree. The new variable is called
threads_tree. For printing list of threads, use the new AVL tree walker
mechanism.

This solves half of ticket #48.
