898	6832 d 20 h	jermar	/kernel/trunk/	Minor changes.
897	6833 d 10 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	6833 d 13 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	6833 d 17 h	jermar	/kernel/trunk/	Move i8042 driver to genarch as it might be used by more architectures.
883	6834 d 22 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	6836 d 14 h	jermar	/kernel/trunk/arch/sparc64/	Fixes in sparc64 preliminary TLB miss handler. Compute and insert identity mapping for kernel on the fly.
873	6836 d 22 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add more MMU helper functions and make data TLB miss handler more verbose.
863	6839 d 10 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add initial TLB miss handlers.
846	6843 d 17 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Relocate kernel to 4M.
830	6850 d 20 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().
730	6870 d 16 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6872 d 12 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
646	6904 d 11 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	6907 d 14 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Register window clean, spill and fill handlers.
627	6907 d 17 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	6909 d 8 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	6909 d 11 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	6910 d 10 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. More ITLB and DTLB controlling functions.
570	6914 d 11 h	jermar	/kernel/trunk/arch/sparc64/src/mm/	Missing tlb.c from last commit.
