764	6861 d 14 h	palkovsky	/kernel/trunk/	Tested basic non-cached slab allocation.
763	6861 d 15 h	jermar	/kernel/trunk/	Modify frame.h to use shifting instead of multiplication and division. Define FRAME_WIDTH for all architectures.
762	6861 d 16 h	palkovsky	/kernel/trunk/	Currently not-working SLAB allocator. - slightly changed interface to frame_alloc, allow zone preference
761	6861 d 17 h	jermar	/kernel/trunk/doc/	Remove document describing more relaxed preemption model than the one used in the current kernel.
760	6861 d 17 h	jermar	/kernel/trunk/	mips32 is not supposed to allocate page table. This is done by the generic code now. Remove PTL0 pointer as it is not needed. Remove GET_PTL0_ADDRESS from kernel. Update sparc64 comments in barrier.h.
759	6862 d 4 h	palkovsky	/kernel/trunk/	Skeleton of SLAB allocator.
758	6862 d 7 h	jermar	/kernel/trunk/arch/	sparc64 bugfix. When disabling IMMU and DMMU the kernel has to perform synchronization operation (e.g flush %r or membar #Sync instruction). There is no guarantee that the address contained in %r is in DTLB and therefore the flush instruction can fault. Normally this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler. However, this handler lives in virtually mapped memory and an attempt to execute there while the MMUs are disabled would result in a nested trap leading to error state. Replacing flush %r instruction with membar #Sync, wich is sufficient in this case, fixes this problem.
757	6862 d 9 h	jermar	/kernel/trunk/	Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator. This area contains VGA text frame buffer and should be avoided. falloc2 test now passes on ia64.
756	6863 d 6 h	jermar	/kernel/trunk/	Memory management work. Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find(). Page table address is now extracted from the first (i.e. 'as') argument. Add a lot of infrastructure to make the above possible. sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
755	6864 d 5 h	jermar	/kernel/trunk/	Change page_mapping_find/insert interfaces to take as_t * as first argument and not asid_t as second argument. This change was necessitated by the removal of mapping array from as_area_t and the fact that an address space doesn't have an ASID when it is created.
754	6864 d 6 h	jermar	/kernel/trunk/generic/	Remove address space area mapping array. The information is to be stored directly in page tables. This is to better support 64-bit systems which can have fairly large address space areas.
753	6864 d 13 h	jermar	/kernel/trunk/	Convert ASID management of ia64 to ASID FIFO mechanism. 18-bit RIDs are supported.
752	6864 d 14 h	jermar	/kernel/trunk/generic/include/	Replace % operator by explicit overflow test to make this ADT compile on ia64.
751	6864 d 16 h	jermar	/kernel/trunk/arch/ia64/	Fix initialization of pta.base on ia64.
750	6865 d 10 h	jermar	/kernel/trunk/	ia32 SMP updates. Update info about supported version of Bochs (bump the counter to 2.2.6). Add Task Priority Register type and initialize this register to a known state.
749	6866 d 13 h	jermar	/kernel/trunk/arch/ia64/	ia64 virtual address translation subsystem update.
748	6867 d 14 h	jermar	/kernel/trunk/arch/ia64/	First HT_HASH_ARCH implementation for ia64.
747	6868 d 7 h	jermar	/kernel/trunk/	ia64 work. Add nice wrappers for thash and ttag instructions. Add nice wrappers for accessing reion registers and PTA. Fix set_vhpt_environment(). Allocate and initialize page_ht (a.k.a. VHPT). Add missing header to sparc64. Remove excessive header from debug.h.
746	6868 d 16 h	jermar	/kernel/trunk/	Page hash table modifications.
745	6869 d 9 h	jermar	/kernel/trunk/test/mm/	Fix and cleanup frame allocator tests. falloc1: - fix so that it compiles on ia64 - check that frames is not NULL falloc2: - threads cannot be passed argument in the way this test did (otherwise some threads will use the same value for val) - check that frames is not NULL - free frames at the end of the test
