700	6696 d 13 h	jermar	/kernel/trunk/arch/sparc64/include/	Remove fmath.h
699	6696 d 14 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
691	6698 d 11 h	jermar	/kernel/trunk/arch/	Cleanup.
669	6707 d 5 h	jermar	/kernel/trunk/	sparc64 work. kconsole support. Add non-blocking ofw_getchar().
667	6708 d 8 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	6710 d 6 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	6710 d 15 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Tick interrupt support.
664	6712 d 2 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
658	6715 d 16 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	6716 d 4 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	6718 d 5 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	6719 d 4 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	6720 d 4 h	jermar	/kernel/trunk/	sparc64 work. CPU identification.
634	6721 d 17 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	6722 d 6 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	6722 d 8 h	jermar	/kernel/trunk/arch/sparc64/	sparc64 work. Register window clean, spill and fill handlers.
627	6722 d 11 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.
625	6722 d 11 h	palkovsky	/kernel/trunk/	We are now almost -Wall clean. - redefined atomic_t - deleted many, many unused variables - some minor code cleanups found using compiler warning.
619	6724 d 2 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	6724 d 5 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).
