670 6728 d 2 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 6730 d 21 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6731 d 4 h bondari /kernel/trunk/generic/src/console/ Zones related commands infrastructure for console. Also fixed small bug that caused infinite loop during command parsing  
667 6732 d 0 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 6733 d 22 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 6734 d 8 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.		  
664 6735 d 19 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6736 d 7 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()).		  
662 6737 d 21 h decky /kernel/trunk/ initial syscall table support  
661 6738 d 2 h cejka /uspace/trunk/softfloat/ Softfloat - function for float subtraction added.  
660 6739 d 7 h cejka /uspace/trunk/softfloat/ Fixed some bugs in softfloat after tests.  
659 6739 d 8 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6739 d 8 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 6739 d 20 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).		  
656 6740 d 20 h decky /uspace/trunk/ user space init working  
655 6741 d 1 h jermar /kernel/trunk/arch/ Compilation fixes.  
654 6741 d 2 h jermar /kernel/trunk/generic/src/ Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.		  
653 6741 d 3 h cejka /uspace/trunk/softfloat/ Comparison function for float type added.  
652 6741 d 7 h cejka /uspace/trunk/softfloat/ Some new functions implemented in softfloat lib.  
651 6741 d 19 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 6741 d 21 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.		  
649 6742 d 3 h decky /boot/trunk/arch/ia32/grub/ forgot to touch the binary file  
648 6742 d 3 h decky /boot/trunk/arch/ia32/ store README and COPYING directly in GRUB floppy image  
647 6742 d 10 h cejka /uspace/trunk/softfloat/ Some changes in file structures, small bugfix in __subsf3().  
646 6742 d 21 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.		  
645 6742 d 21 h jermar /boot/trunk/arch/ Let the kernel Makefile decide wether rebuild is required.  
644 6743 d 6 h jermar /kernel/trunk/arch/ Remove unnecessary files or files that are now part of the boot/ module.  
643 6743 d 6 h jermar /boot/trunk/arch/ia32/ Fix paths in ia32 Makefile.
Add userspace binary to ia32 boot image.

calling debug actions if needed.		  
634 6745 d 9 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.
