/kernel/trunk/generic/
Slightly better behaviour with caching on memory sharing.
1539
6687 d 9 h
cejka
/kernel/trunk/generic/src/mm/
Fixed warning about unused variable in non-debug mode.
1495
6688 d 15 h

/kernel/trunk/
Remove three infinite loops introduced yesterday :-)
Make ia64 ready to load 5 ELF images.
1483
6689 d 2 h
jermar
/kernel/trunk/generic/src/
Implement recursive function for deallocating the whole B+tree.
Make use of this function in address space management.
1468
6690 d 0 h
jermar
/kernel/trunk/
Function for destroying address space for which there is no other reference in the kernel.
1461
6690 d 2 h
palkovsky
/kernel/trunk/generic/
Slightly changed semantics of AS_AREA_SEND/RECV.
1437
6692 d 19 h
jermar
/kernel/trunk/generic/src/mm/
Fix used_space_insert() to correctly service an empty used_space B+tree.
1436
6692 d 20 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
6692 d 22 h
palkovsky
/kernel/trunk/
Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
1428
6693 d 17 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
6693 d 18 h
jermar
/kernel/trunk/generic/src/mm/
Support for sharing address space areas backed up by ELF image.
1425
6693 d 20 h
jermar
/kernel/trunk/generic/
Make address space backend data a union.
1424
6693 d 23 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
6694 d 3 h
jermar
/kernel/trunk/
Update page fault handlers to distinguish between different access modes that had caused the page fault.
1417
6695 d 19 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.
1415
6696 d 7 h

/kernel/trunk/generic/
Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount
1413
6696 d 18 h
jermar
/kernel/trunk/generic/
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
1411
6696 d 23 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
6697 d 17 h
jermar
/kernel/trunk/generic/
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
1403
6699 d 7 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.
