958	6632 d 0 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	6659 d 20 h	palkovsky	/kernel/trunk/	Added support for 24-bit framebuffer.
831	6663 d 4 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	6663 d 5 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 6 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
814	6665 d 7 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 5 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	6670 d 22 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
764	6671 d 3 h	palkovsky	/kernel/trunk/	Tested basic non-cached slab allocation.
760	6671 d 7 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 20 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 19 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 2 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6684 d 21 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
724	6686 d 23 h	palkovsky	/kernel/trunk/	Commit of the falloc_bad branch to trunk (719:723).
704	6691 d 3 h	jermar	/kernel/trunk/	Make various mips32 tlb manipulation functions preserve EntryHi register. Cleanup and more precise comments for previous commit.
703	6691 d 7 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 3 h	bondari	/kernel/trunk/	Frame alloc test #1
687	6696 d 3 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 5 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.
