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.

Remove three infinite loops introduced yesterday :-)
Make ia64 ready to load 5 ELF images.

Removes unnecessary parameter for map_physmem syscall.

/kernel/trunk/generic/src/
Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.

palkovsky
/kernel/trunk/
Added syscall that lets kernel regain access to keyboard.
1468
6607 d 7 h
jermar
/kernel/trunk/
Function for destroying address space for which there is no other reference in the kernel.
1467
6607 d 7 h
jermar
/kernel/trunk/generic/src/synch/
Allow usage of blocking synchronization primitives in functions that are also called during system initialization.

Slightly changed semantics of AS_AREA_SEND/RECV.

Reference counting for futexes.
1458

Added console support to gxemul.
Wider information in thread list.

Project missed_clock_ticks also on thread timeslice and run queue relink counter.
1448
6609 d 6 h
palkovsky
/kernel/trunk/generic/src/syscall/
Better SYS_IO
1438
6610 d 1 h

/kernel/trunk/generic/
Correct realtime clock communication.
1437
6610 d 3 h
jermar
/kernel/trunk/generic/src/mm/
Fix used_space_insert() to correctly service an empty used_space B+tree.
1436
6610 d 4 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
6610 d 5 h
palkovsky
/kernel/trunk/
Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
1433
6610 d 8 h
jermar
/kernel/trunk/generic/src/time/
Fix critical bug in timeout processing introduced several hours ago.
1431
6610 d 12 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
6610 d 14 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
6611 d 1 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
6611 d 2 h
jermar
/kernel/trunk/generic/src/mm/
Support for sharing address space areas backed up by ELF image.
1425
6611 d 4 h
jermar
/kernel/trunk/generic/
Make address space backend data a union.
1424
6611 d 6 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
6611 d 10 h
jermar
/kernel/trunk/
Update page fault handlers to distinguish between different access modes that had caused the page fault.
1417
6613 d 2 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
6613 d 13 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.
1415
6613 d 15 h
jermar
/kernel/trunk/generic/
Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount
1414
6613 d 15 h
jermar
/kernel/trunk/generic/src/synch/
Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.
Update comments.
1413
6614 d 2 h
jermar
/kernel/trunk/generic/
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
1411
6614 d 7 h
jermar
/kernel/trunk/
Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.
1409
6615 d 0 h
jermar
/kernel/trunk/generic/
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
1403
6616 d 14 h
jermar
/kernel/trunk/generic/src/mm/
Fixes of the used_space management code.
Switch as_area_destroy() and as_area_resize() to use the used_space map.
as_area_steal() not switched as it will undergo further changes.
