1544 6548 d 19 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1507 6549 d 19 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6549 d 21 h jermar /kernel/trunk/ Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.

1494 6550 d 9 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1484 6550 d 19 h palkovsky /kernel/trunk/generic/include/ Added EINVAL error code.  
1474 6551 d 11 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1468 6551 d 17 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1461 6551 d 19 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1460 6551 d 21 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1440 6554 d 9 h palkovsky /kernel/trunk/generic/include/ Added error code for timeouts.  
1438 6554 d 11 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.  
1434 6554 d 15 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1431 6554 d 22 h jermar /kernel/trunk/generic/ Add missed_clock_ticks to CPU structure so that clock() can detect missed timer interrupts.
Architectures are required to support this in order to make time keeping accurate.
 
1429 6554 d 23 h jermar /kernel/trunk/generic/ Make ddi_physmem_map() accept address space area flags instead of writable switch.
Thus even these types of address space areas can turn caching on, if it is desired.
 
1428 6555 d 10 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.
 
1425 6555 d 13 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 6555 d 15 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.
 
1423 6555 d 19 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1417 6557 d 12 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.
 
1416 6557 d 23 h jermar /kernel/trunk/generic/ Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change.
