867	6640 d 6 h	jermar	/kernel/trunk/	Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64. sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.
863	6640 d 21 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add initial TLB miss handlers.
846	6645 d 4 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Relocate kernel to 4M.
830	6652 d 7 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	6653 d 21 h	jermar	/kernel/trunk/	Reimplement ASID stealing logic. This time, hopefully, with correct synchronization.
821	6653 d 22 h	jermar	/kernel/trunk/arch/sparc64/src/mm/	Do not add CONFIG_STACK_SIZE to kernel.size.
820	6653 d 22 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	6654 d 8 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
813	6654 d 21 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	6656 d 6 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	6656 d 7 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
756	6661 d 21 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	6672 d 3 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6673 d 23 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
684	6685 d 6 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	6705 d 22 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	6709 d 1 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Register window clean, spill and fill handlers.
627	6709 d 4 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	6710 d 19 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	6710 d 22 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).
