1420 6557 d 1 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		  
1419 6558 d 14 h jermar /uspace/trunk/tetris/ Import BSD tetris from OpenBSD.
Needs to be integrated and ported.		  
1418 6558 d 15 h jermar /uspace/trunk/ Sync with kernel.
Args for IPC_M_AS_AREA_SEND changed.		  
1417 6558 d 15 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 6559 d 2 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 6559 d 3 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 6559 d 3 h jermar /kernel/trunk/generic/src/synch/ Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.
Update comments.		  
1413 6559 d 14 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.		  
1412 6559 d 14 h jermar /uspace/trunk/init/ test_as_send() -> test_as_area_send()  
1411 6559 d 19 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.		  
1410 6559 d 22 h jermar /kernel/trunk/arch/sparc64/ Modify sparc64 to choose optimal page size in each invocation of hw_map().
Use hw_map() to map keyboard device memory.		  
1409 6560 d 13 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1408 6560 d 14 h palkovsky /uspace/trunk/libc/generic/ Fix gcc mips bug.  
1407 6561 d 1 h palkovsky /uspace/trunk/libc/ Small updates to asynchronous framework.  
1406 6561 d 19 h jermar /uspace/trunk/libc/ Change linker scripts so that heap a dedicated address space area can be allocated for heap.
This will be essential in separating anonymous memory and memory backed by some other memory object.		  
1405 6561 d 20 h decky /uspace/trunk/libc/generic/ fix syntax bug  
1404 6562 d 1 h palkovsky /uspace/trunk/ Added some cleanups.  
1403 6562 d 2 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.		  
1402 6562 d 15 h decky /uspace/trunk/ add missing stuff  
1401 6562 d 15 h decky /boot/trunk/arch/ppc64/loader/ add missing stuff to compile
