1576 6729 d 2 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1573 6729 d 4 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1571 6729 d 4 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.		  
1568 6729 d 5 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1554 6729 d 23 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1550 6730 d 5 h jermar /kernel/trunk/generic/src/mm/ Remove left over piece of code for increasing reference count in ELF backend.  
1549 6730 d 6 h vana /kernel/trunk/generic/src/adt/ Bitmap functions patch  
1546 6730 d 7 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of ELF image backed address space area.  
1545 6730 d 7 h jermar /kernel/trunk/generic/src/mm/ Add reference to shared frames of anonymous address space area.  
1544 6730 d 7 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1539 6730 d 14 h cejka /kernel/trunk/generic/src/mm/ Fixed warning about unused variable in non-debug mode.  
1507 6731 d 7 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6731 d 9 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.
O		  
1495 6731 d 20 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1494 6731 d 21 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1484 6732 d 7 h palkovsky /kernel/trunk/generic/include/ Added EINVAL error code.  
1483 6732 d 7 h jermar /kernel/trunk/generic/src/ Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.		  
1474 6732 d 23 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1468 6733 d 5 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1467 6733 d 5 h jermar /kernel/trunk/generic/src/synch/ Allow usage of blocking synchronization primitives in functions that are also called during system initialization.  
1461 6733 d 7 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1460 6733 d 9 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1458 6733 d 23 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.		  
1457 6734 d 0 h jermar /kernel/trunk/generic/src/time/ Project missed_clock_ticks also on thread timeslice and run queue relink counter.  
1448 6735 d 4 h palkovsky /kernel/trunk/generic/src/syscall/ Better SYS_IO  
1440 6735 d 22 h palkovsky /kernel/trunk/generic/include/ Added error code for timeouts.  
1438 6735 d 23 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.  
1437 6736 d 0 h jermar /kernel/trunk/generic/src/mm/ Fix used_space_insert() to correctly service an empty used_space B+tree.  
1436 6736 d 1 h jermar /kernel/trunk/generic/src/mm/ Fight TLB inconsistency by proper placing of tlb_shootdown_start() and tlb_shootdown_finalize() in as.c.  
1434 6736 d 3 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1433 6736 d 6 h jermar /kernel/trunk/generic/src/time/ Fix critical bug in timeout processing introduced several hours ago.  
1431 6736 d 10 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 6736 d 11 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 6736 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.		  
1426 6737 d 0 h jermar /kernel/trunk/generic/src/mm/ Support for sharing address space areas backed up by ELF image.  
1425 6737 d 1 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 6737 d 4 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 6737 d 8 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1417 6739 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.		  
1416 6739 d 11 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.
