684 6834 d 6 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 6834 d 6 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
682 6834 d 7 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build  
681 6834 d 9 h jermar /kernel/trunk/ Minor changes.  
680 6837 d 22 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64		  
679 6837 d 23 h decky /boot/trunk/arch/amd64/ AMD64 support  
678 6838 d 0 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6838 d 2 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6838 d 2 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6838 d 8 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6838 d 9 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6838 d 23 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
672 6839 d 23 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.		  
671 6840 d 0 h vana /kernel/trunk/ i8042 bug fix...  
670 6840 d 3 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 6842 d 22 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6843 d 5 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 6844 d 1 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 6845 d 23 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 6846 d 9 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.		  
664 6847 d 20 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6848 d 9 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 6849 d 22 h decky /kernel/trunk/ initial syscall table support  
661 6850 d 3 h cejka /uspace/trunk/softfloat/ Softfloat - function for float subtraction added.  
660 6851 d 9 h cejka /uspace/trunk/softfloat/ Fixed some bugs in softfloat after tests.  
659 6851 d 10 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6851 d 10 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 6851 d 21 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 6852 d 21 h decky /uspace/trunk/ user space init working  
655 6853 d 2 h jermar /kernel/trunk/arch/ Compilation fixes.  
654 6853 d 3 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 6853 d 4 h cejka /uspace/trunk/softfloat/ Comparison function for float type added.  
652 6853 d 8 h cejka /uspace/trunk/softfloat/ Some new functions implemented in softfloat lib.  
651 6853 d 20 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 6853 d 22 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 6854 d 4 h decky /boot/trunk/arch/ia32/grub/ forgot to touch the binary file  
648 6854 d 4 h decky /boot/trunk/arch/ia32/ store README and COPYING directly in GRUB floppy image  
647 6854 d 11 h cejka /uspace/trunk/softfloat/ Some changes in file structures, small bugfix in __subsf3().  
646 6854 d 22 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 6854 d 23 h jermar /boot/trunk/arch/ Let the kernel Makefile decide wether rebuild is required.
