720	6718 d 23 h	bondari	/kernel/branches/falloc_bad/	Failing frame_alloc branch - revision 719
703	6723 d 1 h	jermar	/kernel/trunk/	Memory management work. - vm.* -> as.* (as like address space is, imho, more fitting) - Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid(). - Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault(). - Add high-level page fault handler as_page_fault(). - Add as_area_load_mapping().
700	6726 d 0 h	jermar	/kernel/trunk/arch/sparc64/include/	Remove fmath.h
699	6726 d 0 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
691	6727 d 21 h	jermar	/kernel/trunk/arch/	Cleanup.
684	6727 d 23 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	6736 d 15 h	jermar	/kernel/trunk/	sparc64 work. kconsole support. Add non-blocking ofw_getchar().
667	6737 d 18 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	6739 d 16 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	6740 d 2 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Tick interrupt support.
664	6741 d 13 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
663	6742 d 2 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()).
658	6745 d 3 h	jermar	/kernel/trunk/arch/sparc64/include/	sparc64 work. Add functions to read and write TICK and TICK_compare registers. Add types describing TICK and TICK_compare registers.
657	6745 d 14 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).
651	6747 d 13 h	decky	/kernel/trunk/	remove arch/$ARCH/boot where not needed, change global Makefile accordingly remove early_mapping() (breaks ppc32 for now) change early heap initialization (required for init to work)
650	6747 d 15 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	6748 d 15 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.
644	6749 d 0 h	jermar	/kernel/trunk/arch/	Remove unnecessary files or files that are now part of the boot/ module.
640	6749 d 14 h	jermar	/kernel/trunk/	sparc64 work. CPU identification.
634	6751 d 3 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.
