815	6685 d 0 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
813	6685 d 13 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	6686 d 22 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	6686 d 22 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
756	6692 d 13 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	6697 d 14 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	6702 d 19 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6704 d 14 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
684	6715 d 22 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	6724 d 14 h	jermar	/kernel/trunk/	sparc64 work. kconsole support. Add non-blocking ofw_getchar().
667	6725 d 17 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	6727 d 15 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	6728 d 1 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Tick interrupt support.
664	6729 d 12 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
663	6730 d 1 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	6733 d 13 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	6735 d 14 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	6736 d 14 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	6737 d 13 h	jermar	/kernel/trunk/	sparc64 work. CPU identification.
634	6739 d 2 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.
