983	6632 d 19 h	palkovsky	/kernel/trunk/	Fixed shrinking of as area.
958	6633 d 15 h	jermar	/kernel/trunk/	Nicer ia32 interrupt handlers and structures holding interrupted context data. Unify the name holding interrupted context data on all architectures to be istate.
836	6661 d 11 h	palkovsky	/kernel/trunk/	Added support for 24-bit framebuffer.
831	6664 d 19 h	jermar	/kernel/trunk/	Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings. This helps to distinguish valid entries from not present entries with 0 content (i.e. not present entries with PFN 0 and other bits cleared).
830	6664 d 21 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	6666 d 22 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
814	6666 d 22 h	palkovsky	/kernel/trunk/	Cleanup o frame allocator. Removed early_malloc & initial heap. Will break ia64, ppc & sparc. Added e820 table print.
793	6668 d 20 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	6672 d 14 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
764	6672 d 19 h	palkovsky	/kernel/trunk/	Tested basic non-cached slab allocation.
760	6672 d 22 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	6674 d 11 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	6675 d 10 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	6684 d 17 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6686 d 13 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
724	6688 d 14 h	palkovsky	/kernel/trunk/	Commit of the falloc_bad branch to trunk (719:723).
704	6692 d 18 h	jermar	/kernel/trunk/	Make various mips32 tlb manipulation functions preserve EntryHi register. Cleanup and more precise comments for previous commit.
703	6692 d 22 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	6697 d 18 h	bondari	/kernel/trunk/	Frame alloc test #1
687	6697 d 18 h	jermar	/kernel/trunk/	Memory management work. Pass address space identifier to functions in page_operations to support single global page hash table.
