704 6866 d 6 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.
 
703 6866 d 10 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
702 6866 d 11 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
700 6869 d 9 h jermar /kernel/trunk/arch/sparc64/include/ Remove fmath.h  
699 6869 d 10 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.
 
696 6871 d 3 h decky /kernel/trunk/arch/amd64/ AMD64 SMP boots again  
695 6871 d 4 h decky /kernel/trunk/arch/amd64/ make AMD64 boot again (using grub, see /boot tree), SMP is still broken  
694 6871 d 5 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
693 6871 d 5 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
691 6871 d 6 h jermar /kernel/trunk/arch/ Cleanup.  
690 6871 d 6 h bondari /kernel/trunk/arch/ Fixes of 3-param frame_alloc() function calls  
689 6871 d 6 h bondari /kernel/trunk/ Frame alloc test #1  
687 6871 d 7 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
685 6871 d 8 h decky /kernel/trunk/arch/amd64/ AMD64 PM initialization  
684 6871 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.
 
682 6871 d 9 h decky /kernel/trunk/arch/ia32/src/mm/ fix ia32 build  
680 6875 d 0 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64
 
674 6875 d 11 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6876 d 1 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
672 6877 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 6877 d 2 h vana /kernel/trunk/ i8042 bug fix...  
670 6877 d 5 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 6880 d 0 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().
 
667 6881 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 6883 d 1 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 6883 d 11 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Tick interrupt support.
 
664 6884 d 22 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.
 
663 6885 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()).
 
659 6888 d 12 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
658 6888 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 6889 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 6890 d 5 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6890 d 22 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 6891 d 0 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 6892 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 6892 d 9 h jermar /kernel/trunk/arch/ Remove unnecessary files or files that are now part of the boot/ module.

CPU identification.

Add commands to debugger to allow for simple profiling or
calling debug actions if needed.
 
634 6894 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.
 
633 6895 d 1 h palkovsky /kernel/trunk/arch/ Fixes of compilation of atomic.
