1431 6575 d 21 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.		  
/kernel/trunk/generic/include/cpu.h
/kernel/trunk/generic/src/time/clock.c
1430 6575 d 23 h jermar /uspace/trunk/ Sync with kernel.
Make map_physmem() pass address space area flags instead of boolean switch.

Try to map fb memory with caching enabled.

/uspace/trunk/libc/include/ddi.h
1429 6575 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.		  
/kernel/trunk/generic/include/ddi/ddi_arg.h
/kernel/trunk/generic/src/ddi/ddi.c
1428 6576 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.

1424 6576 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.

/uspace/trunk/libc/arch/ia64/_link.ld.in
1420 6576 d 22 h jermar /kernel/trunk/ Upgrade toolchain to use gcc 4.1.1.
ia64 still cannot be built with combination of binutils 2.16.1 and gcc 4.1.x

1418 6578 d 11 h jermar /uspace/trunk/ Sync with kernel.
Args for IPC_M_AS_AREA_SEND changed.		  
/uspace/trunk/init/init.c
/uspace/trunk/ns/ns.c
1417 6578 d 11 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.

/kernel/trunk/generic/src/ipc/sysipc.c
/kernel/trunk/generic/src/mm/as.c
1416 6578 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.		  
/kernel/trunk/generic/include/synch/condvar.h
/kernel/trunk/generic/src/synch/condvar.c
1415 6579 d 0 h jermar /kernel/trunk/generic/ Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount

/kernel/trunk/generic/src/mm/as.c
1414 6579 d 0 h jermar /kernel/trunk/generic/src/synch/ Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.
Update comments.		  
/kernel/trunk/generic/src/synch/futex.c
1413 6579 d 11 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
