669 6710 d 21 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6711 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 6712 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 6713 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 6714 d 8 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.		  
664 6715 d 19 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6716 d 8 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 6717 d 21 h decky /kernel/trunk/ initial syscall table support  
661 6718 d 2 h cejka /uspace/trunk/softfloat/ Softfloat - function for float subtraction added.  
660 6719 d 8 h cejka /uspace/trunk/softfloat/ Fixed some bugs in softfloat after tests.  
659 6719 d 9 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6719 d 9 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 6719 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 6720 d 20 h decky /uspace/trunk/ user space init working  
655 6721 d 1 h jermar /kernel/trunk/arch/ Compilation fixes.  
654 6721 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 6721 d 3 h cejka /uspace/trunk/softfloat/ Comparison function for float type added.  
652 6721 d 7 h cejka /uspace/trunk/softfloat/ Some new functions implemented in softfloat lib.  
651 6721 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 6721 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 6722 d 3 h decky /boot/trunk/arch/ia32/grub/ forgot to touch the binary file  
648 6722 d 3 h decky /boot/trunk/arch/ia32/ store README and COPYING directly in GRUB floppy image  
647 6722 d 10 h cejka /uspace/trunk/softfloat/ Some changes in file structures, small bugfix in __subsf3().  
646 6722 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 6722 d 22 h jermar /boot/trunk/arch/ Let the kernel Makefile decide wether rebuild is required.  
644 6723 d 6 h jermar /kernel/trunk/arch/ Remove unnecessary files or files that are now part of the boot/ module.  
643 6723 d 6 h jermar /boot/trunk/arch/ia32/ Fix paths in ia32 Makefile.
Add userspace binary to ia32 boot image.		  
642 6723 d 7 h jermar /boot/trunk/arch/ia32/ Complete ia32 build boot infrastructure.  
641 6723 d 7 h jermar /boot/trunk/arch/sparc64/ Add complete sparc64 boot build infrastructure.  
640 6723 d 20 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
639 6723 d 23 h jermar /boot/trunk/arch/sparc64/ Move SILO files to newly created silo/ directory.  
638 6724 d 0 h jermar /boot/trunk/arch/ Boot loader for sparc64 port.  
637 6724 d 0 h jermar /boot/trunk/ Trunk for booting.  
636 6724 d 0 h jermar /boot/ Infrastructure for booting.  
635 6724 d 20 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 6725 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.		  
633 6725 d 22 h palkovsky /kernel/trunk/arch/ Fixes of compilation of atomic.  
632 6725 d 22 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
