684 6751 d 8 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 6751 d 8 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
682 6751 d 9 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build  
681 6751 d 11 h jermar /kernel/trunk/ Minor changes.  
680 6755 d 1 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64		  
678 6755 d 2 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6755 d 5 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6755 d 5 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6755 d 10 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6755 d 11 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6756 d 1 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
672 6757 d 1 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.		  
671 6757 d 2 h vana /kernel/trunk/ i8042 bug fix...  
670 6757 d 6 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 6760 d 1 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6760 d 8 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 6761 d 4 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 6763 d 2 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 6763 d 11 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.		  
664 6764 d 22 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6765 d 11 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 6767 d 0 h decky /kernel/trunk/ initial syscall table support  
659 6768 d 12 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6768 d 12 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 6769 d 0 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 6770 d 5 h jermar /kernel/trunk/arch/ Compilation fixes.  
654 6770 d 5 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.		  
651 6770 d 23 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 6771 d 1 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 6772 d 0 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 6772 d 10 h jermar /kernel/trunk/arch/ Remove unnecessary files or files that are now part of the boot/ module.  
640 6773 d 0 h jermar /kernel/trunk/ sparc64 work.

calling debug actions if needed.		  
634 6774 d 12 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.

632 6775 d 2 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add trap_install_handler().
Use trap_install_handler() to install register window clean, spill and fill handlers.		  
631 6775 d 2 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
630 6775 d 3 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Register window clean, spill and fill handlers.		  
629 6775 d 4 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6775 d 5 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB
