684 6734 d 17 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.		  
682 6734 d 18 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build  
680 6738 d 10 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64		  
674 6738 d 20 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6739 d 10 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
672 6740 d 10 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.		  
671 6740 d 11 h vana /kernel/trunk/ i8042 bug fix...  
670 6740 d 15 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 6743 d 10 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
667 6744 d 13 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 6746 d 11 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 6746 d 20 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.		  
664 6748 d 7 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6748 d 20 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()).		  
659 6751 d 21 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6751 d 21 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 6752 d 9 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 6753 d 14 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6754 d 8 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 6754 d 10 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 6755 d 9 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 6755 d 19 h jermar /kernel/trunk/arch/ Remove unnecessary files or files that are now part of the boot/ module.  
640 6756 d 9 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6757 d 8 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 6757 d 21 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 6758 d 10 h palkovsky /kernel/trunk/arch/ Fixes of compilation of atomic.  
632 6758 d 11 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 6758 d 11 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
630 6758 d 12 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Register window clean, spill and fill handlers.		  
629 6758 d 13 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6758 d 14 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
627 6758 d 15 h jermar /kernel/trunk/ Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

sparc64 work.
TBA must be set before a function call when MMU is switched off.		  
625 6758 d 16 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.		  
623 6758 d 22 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
622 6759 d 12 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
619 6760 d 6 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Functions for disabling/enabling MMU.
TLB initialization.
Identity mapping of first 4M for kernel.
Switch to kernel copy of trap table.		  
618 6760 d 9 h jermar /kernel/trunk/arch/mips32/src/mm/ Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.  
617 6760 d 9 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Support for TLB Demap operations.
Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid).		  
615 6760 d 21 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6761 d 7 h palkovsky /kernel/trunk/ Added support for mips breakpoints.
We have a kind of kernel debugger :-)
Breakpoints on JMP/Branch instructions are not supported and
they are reported after the breakpoint is fired and exited as
a BranchDelay exception. If we found a way, how to detect these
instructions, we would be able to support them as 'one-time' breakpoints.
