792	6853 d 16 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
756	6859 d 6 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.
747	6864 d 7 h	jermar	/kernel/trunk/	ia64 work. Add nice wrappers for thash and ttag instructions. Add nice wrappers for accessing reion registers and PTA. Fix set_vhpt_environment(). Allocate and initialize page_ht (a.k.a. VHPT). Add missing header to sparc64. Remove excessive header from debug.h.
730	6869 d 12 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6871 d 8 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
684	6882 d 15 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.
669	6891 d 7 h	jermar	/kernel/trunk/	sparc64 work. kconsole support. Add non-blocking ofw_getchar().
667	6892 d 11 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Rename saving_handler() to preemptible_handler() and fix it to make sparc64 kernel preemptive. Add two handlers for two fatal exceptions (i.e. instruction_access_exception and mem_address_not_aligned. Fix panic_printf() to not allocate its own register window.
666	6894 d 8 h	jermar	/kernel/trunk/	sparc64 work. Fix clean_window trap handler so that it clears output registers instead of input registers! Fix interrupt handlers to save global registers.
665	6894 d 18 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Tick interrupt support.
664	6896 d 5 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
663	6896 d 18 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Initial interrupt_vector_trap handler and fixes needed to make it do the right thing (i.e. panic()).
657	6900 d 7 h	jermar	/kernel/trunk/	sparc64 work. Context again. It turns out, according to SCD 2.4, that registers that didn't have to be saved were saved (%o1 - %o5) and registers that had to be saved were not saved (%i0 - %i5, %l0 - %l7).
650	6902 d 7 h	jermar	/kernel/trunk/	sparc64 work. Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions. Fix context save/restore to save/restore register %i7.
646	6903 d 7 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.
640	6904 d 7 h	jermar	/kernel/trunk/	sparc64 work. CPU identification.
634	6905 d 19 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Better way of trap table organization. Kernel trap handlers now "stay" on addresses on wich they were linked.
632	6906 d 8 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Add trap_install_handler(). Use trap_install_handler() to install register window clean, spill and fill handlers.
630	6906 d 10 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Register window clean, spill and fill handlers.
627	6906 d 13 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.
