830	6663 d 9 h	jermar	/kernel/trunk/	Make ASID FIFO for mips32 be allocated statically. Make ASID FIFO for sparc64 and ia64 be allocated dynamically. Fix ia64 to call asid_fifo_init(). All three architectures now call asid_fifo_init() from as_arch_init().
815	6665 d 10 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
814	6665 d 11 h	palkovsky	/kernel/trunk/	Cleanup o frame allocator. Removed early_malloc & initial heap. Will break ia64, ppc & sparc. Added e820 table print.
793	6667 d 8 h	jermar	/kernel/trunk/	Use hash_table_get_instance instead of list_get_instance. Rename page_operations to page_mapping_operations. Rename page_pt_operations to pt_mapping_operations. Rename page_ht_operations to ht_mapping_operations.
765	6671 d 2 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
764	6671 d 7 h	palkovsky	/kernel/trunk/	Tested basic non-cached slab allocation.
760	6671 d 10 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.
756	6672 d 23 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	6673 d 22 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.
730	6683 d 5 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6685 d 1 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
724	6687 d 2 h	palkovsky	/kernel/trunk/	Commit of the falloc_bad branch to trunk (719:723).
704	6691 d 7 h	jermar	/kernel/trunk/	Make various mips32 tlb manipulation functions preserve EntryHi register. Cleanup and more precise comments for previous commit.
703	6691 d 10 h	jermar	/kernel/trunk/	Memory management work. - vm.* -> as.* (as like address space is, imho, more fitting) - Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid(). - Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault(). - Add high-level page fault handler as_page_fault(). - Add as_area_load_mapping().
689	6696 d 7 h	bondari	/kernel/trunk/	Frame alloc test #1
687	6696 d 7 h	jermar	/kernel/trunk/	Memory management work. Pass address space identifier to functions in page_operations to support single global page hash table.
684	6696 d 8 h	jermar	/kernel/trunk/	Memory management work. Move generic 4-level page table interface to genarch and enable architectures to use different virtual memory mechanisms (e.g. page hash tables). Start page hash table support. Switch ia64 and sparc64 to page hash tables. Other architectures keep on using 4-level page table interface.
623	6720 d 13 h	jermar	/kernel/trunk/	Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros. SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations in dynamically allocated structures on which spinlock_initialize() is called after their creation. SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations of global spinlocks. It declares and initializes the spinlock. Moreover, both macros are empty on UP so that -Wall warnings about unused structures get supressed.
618	6722 d 0 h	jermar	/kernel/trunk/arch/mips32/src/mm/	Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.
612	6723 d 4 h	jermar	/kernel/trunk/arch/mips32/src/mm/	Weaken the assumption, that PageMask register contains the right mask everytime. As a result, TLB exceptions will explicitly write this register when filling TLB entry. Adjust tlb_print() on mips32 to print PageMask as well.
