684 6743 d 14 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.		  
683 6743 d 14 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
682 6743 d 14 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build  
681 6743 d 17 h jermar /kernel/trunk/ Minor changes.  
680 6747 d 6 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64		  
679 6747 d 7 h decky /boot/trunk/arch/amd64/ AMD64 support  
678 6747 d 8 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6747 d 10 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6747 d 10 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6747 d 15 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6747 d 17 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6748 d 7 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
672 6749 d 6 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.		  
671 6749 d 8 h vana /kernel/trunk/ i8042 bug fix...  
670 6749 d 11 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 6752 d 6 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6752 d 13 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 6753 d 9 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 6755 d 7 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 6755 d 17 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.		  
664 6757 d 4 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6757 d 16 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 6759 d 6 h decky /kernel/trunk/ initial syscall table support  
661 6759 d 11 h cejka /uspace/trunk/softfloat/ Softfloat - function for float subtraction added.  
660 6760 d 16 h cejka /uspace/trunk/softfloat/ Fixed some bugs in softfloat after tests.  
659 6760 d 17 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6760 d 18 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 6761 d 5 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 6762 d 5 h decky /uspace/trunk/ user space init working  
655 6762 d 10 h jermar /kernel/trunk/arch/ Compilation fixes.  
654 6762 d 11 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 6762 d 12 h cejka /uspace/trunk/softfloat/ Comparison function for float type added.  
652 6762 d 16 h cejka /uspace/trunk/softfloat/ Some new functions implemented in softfloat lib.  
651 6763 d 4 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 6763 d 6 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 6763 d 12 h decky /boot/trunk/arch/ia32/grub/ forgot to touch the binary file  
648 6763 d 12 h decky /boot/trunk/arch/ia32/ store README and COPYING directly in GRUB floppy image  
647 6763 d 19 h cejka /uspace/trunk/softfloat/ Some changes in file structures, small bugfix in __subsf3().  
646 6764 d 6 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 6764 d 7 h jermar /boot/trunk/arch/ Let the kernel Makefile decide wether rebuild is required.
