830	6656 d 2 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().
823	6657 d 16 h	jermar	/kernel/trunk/	Reimplement ASID stealing logic. This time, hopefully, with correct synchronization.
821	6657 d 17 h	jermar	/kernel/trunk/arch/sparc64/src/mm/	Do not add CONFIG_STACK_SIZE to kernel.size.
820	6657 d 18 h	jermar	/kernel/trunk/	Convert size_t, count_t and index_t to 64-bits on 64-bit architectures. Change some pfn_t usages to count_t, size_t and index_t.
815	6658 d 3 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
813	6658 d 16 h	jermar	/kernel/trunk/	Change ia64 kernel image to link and load at 0x100000 where it (or its heap or stack) won't mess up with the ROM region. Blacklist ia64 frame 0 from frame allocator so that 0 won't be returned to malloc and friends. This can be reenabled again once the kernel is not identity mapped.
793	6660 d 1 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.
792	6660 d 2 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
756	6665 d 16 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.
730	6675 d 22 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6677 d 18 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
684	6689 d 1 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.
646	6709 d 17 h	jermar	/kernel/trunk/	Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error. sparc64 work. Reorganize kernel vs. userspace memory layout. Add panic_printf(). Turn dummy() into nop rather than into infinite loop.
630	6712 d 20 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Register window clean, spill and fill handlers.
627	6712 d 23 h	jermar	/kernel/trunk/	Fix ia64 and sparc64 to compile with new atomic_t. Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t. sparc64 work. TBA must be set before a function call when MMU is switched off.
619	6714 d 14 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Functions for disabling/enabling MMU. TLB initialization. Identity mapping of first 4M for kernel. Switch to kernel copy of trap table.
617	6714 d 17 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Support for TLB Demap operations. Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid).
613	6715 d 16 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. More ITLB and DTLB controlling functions.
570	6719 d 17 h	jermar	/kernel/trunk/arch/sparc64/src/mm/	Missing tlb.c from last commit.
538	6722 d 22 h	jermar	/kernel/trunk/	Buddy allocator cleanup and fixes II. - Rewrite IS_BUDDY_LEFT_BLOCK so that it does not need floating point on some architectures (e.g. IA-64). - Get rid of IS_BUDDY_RIGHT_BLOCK. - Make sparc64 use zone_create_in_region.
