2557 6067 d 4 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 6067 d 6 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2550 6068 d 0 h cejka /trunk/ Fixed naming convention in IPC.  
2538 6072 d 6 h vana /trunk/kernel/arch/ia64/include/drivers/ Macro naming correction  
2537 6072 d 6 h vana /trunk/kernel/arch/ia64/include/drivers/ IA64 keyboard lost headerfile  
2527 6080 d 5 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 6081 d 8 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.
 
2519 6083 d 4 h vana /trunk/ Pack ski version of HelenOS to image.boot loader  
2517 6086 d 4 h vana /trunk/kernel/arch/ia64/include/ Missing header file  
2516 6086 d 19 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2515 6086 d 19 h vana /trunk/kernel/arch/ia64/include/ IA64 legacy I/O  
2514 6086 d 19 h vana /trunk/kernel/arch/ia64/ IA64 Makefile changes for simics  
2513 6086 d 19 h vana /trunk/kernel/arch/ia64/src/ IA64 simics keyboard support  
2512 6086 d 19 h vana /trunk/kernel/arch/ia64/src/ IA64 loader parameter  
2510 6090 d 20 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.
 
2505 6124 d 7 h jermar /trunk/kernel/genarch/src/softint/ Minor cleanup of softint.  
2504 6128 d 21 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.
 
2503 6128 d 22 h jermar /trunk/kernel/generic/src/adt/ Get rid of code duplicities in the insert path into an AVL tree.  
2502 6129 d 3 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.
 
2501 6129 d 3 h jermar /trunk/kernel/generic/ Add explicit type for an AVL tree key.
Add function to walk an AVL tree using a supplied walker.
