1461 6741 d 7 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1434 6744 d 3 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1428 6744 d 22 h palkovsky /kernel/trunk/generic/ Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA.
 
1417 6747 d 0 h jermar /kernel/trunk/generic/ Modify as_area_share() to accept destination area flags bitmask from the sender
(i.e. the sender can limit access mode to the shared area for the recipient).
Modify IPC_M_AS_AREA_SEND code to support this. Arguments for sender: arg1=as_area,
arg2=size, arg3=flags_mask.

The mechanism seems to work, but the page fault handlers need to be altered to
distinguish between faults under different access modes.
 
1413 6747 d 23 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
 
1396 6751 d 1 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().
 
1364 6755 d 7 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1359 6756 d 4 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.  
1346 6756 d 11 h palkovsky /kernel/trunk/generic/src/ipc/ Small updates to IPC regarding AS_SEND.  
1329 6758 d 4 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1297 6765 d 6 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.
 
1293 6767 d 6 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6767 d 9 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1281 6769 d 23 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.  
1258 6772 d 23 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.
 
1248 6775 d 4 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1141 6802 d 7 h palkovsky /kernel/trunk/generic/src/ipc/ Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep.
 
1090 6814 d 1 h palkovsky /kernel/trunk/generic/ Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages.
 
1088 6814 d 8 h palkovsky /kernel/trunk/generic/ More IPC stuff, added correct closing of connections from both sides.  
1086 6814 d 22 h palkovsky /kernel/trunk/generic/ Untested better IPC functions.
* There is some bug in MIPS, unpredicatbly sometimes the thread gets mapped
different frame for stack.
