1382	6551 d 16 h	decky	/kernel/trunk/	make hardware memory mapping more generic
1376	6553 d 0 h	jermar	/kernel/trunk/	Change the way the framebuffer is mapped so that sparc64 is usable again.
1191	6588 d 4 h	jermar	/kernel/trunk/	Kernel support for SYS_ENABLE_IOSPACE. amd64 and ia32 provide dummy implementation thereof.
1106	6610 d 15 h	jermar	/kernel/trunk/arch/	Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.
938	6620 d 19 h	jermar	/kernel/trunk/	Basic support for loading ELF object files. ia64, amd64, ia32 working. mips32 requires some attention.
897	6633 d 13 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	6633 d 17 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.
883	6635 d 1 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.
867	6638 d 22 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.
756	6660 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.
730	6670 d 19 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6672 d 15 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
684	6683 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.
667	6693 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.
664	6697 d 12 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
663	6698 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()).
646	6704 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	6705 d 14 h	jermar	/kernel/trunk/	sparc64 work. CPU identification.
630	6707 d 17 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Register window clean, spill and fill handlers.
619	6709 d 11 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.
