897	6825 d 21 h	jermar	/kernel/trunk/	sparc64 work. Fix KBD_VIRT_ADDRESS. Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial. Add after_thread_ran() to the scheduler. Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack. Add dummy after_thread_ran_arch() to all other architectures. Add dtlb_insert_mapping() to promote code reuse.
895	6826 d 0 h	jermar	/kernel/trunk/	sparc64 work. Very raw and fragile preliminary standalone keyboard support - polling mode only. Because of a workaround in Simics, the scan codes are the same as on ia32.
894	6826 d 4 h	jermar	/kernel/trunk/	Move i8042 driver to genarch as it might be used by more architectures.
883	6827 d 9 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Switch console to framebuffer (needs proper detection and initialization). No native keyboard support, so far. Memory management trap handler fixes. Do not use OpenFirmware trap table anymore.
877	6829 d 1 h	jermar	/kernel/trunk/arch/sparc64/	Fixes in sparc64 preliminary TLB miss handler. Compute and insert identity mapping for kernel on the fly.
873	6829 d 9 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add more MMU helper functions and make data TLB miss handler more verbose.
868	6831 d 6 h	jermar	/kernel/trunk/arch/sparc64/src/mm/	Add missing file.
867	6831 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	6831 d 21 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add initial TLB miss handlers.
846	6836 d 4 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Relocate kernel to 4M.
830	6843 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	6844 d 21 h	jermar	/kernel/trunk/	Reimplement ASID stealing logic. This time, hopefully, with correct synchronization.
821	6844 d 22 h	jermar	/kernel/trunk/arch/sparc64/src/mm/	Do not add CONFIG_STACK_SIZE to kernel.size.
820	6844 d 23 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	6845 d 8 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
813	6845 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	6847 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	6847 d 7 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
756	6852 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	6863 d 3 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
