671 6715 d 15 h vana /kernel/trunk/ i8042 bug fix...  
670 6715 d 18 h vana /kernel/trunk/arch/ia32/src/drivers/ i8042 command word init... It should work on ia32 but I have done it for Indy and I'm not sure it will work because on Silicon should not be the same software in universal microprocesor i8042. So if It will not work I'll remove it and will write i8042 AT function emulation.  
669 6718 d 13 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
667 6719 d 16 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 6721 d 14 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 6722 d 0 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.		  
664 6723 d 11 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6723 d 23 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()).		  
659 6727 d 0 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6727 d 0 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 6727 d 12 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).		  
655 6728 d 17 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6729 d 11 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 6729 d 13 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 6730 d 13 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 6730 d 22 h jermar /kernel/trunk/arch/ Remove unnecessary files or files that are now part of the boot/ module.  
640 6731 d 12 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6732 d 12 h palkovsky /kernel/trunk/ Fixed kconsole resolution of similar commands.
Add commands to debugger to allow for simple profiling or
calling debug actions if needed.		  
634 6733 d 1 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.		  
633 6733 d 14 h palkovsky /kernel/trunk/arch/ Fixes of compilation of atomic.
