895 6740 d 15 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.

894 6740 d 19 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.

Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.		  
889 6741 d 22 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
883 6742 d 0 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.		  
877 6743 d 16 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.

Add more MMU helper functions and make data TLB miss handler more verbose.		  
868 6745 d 21 h jermar /kernel/trunk/arch/sparc64/src/mm/ Add missing file.  
867 6745 d 21 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
864 6746 d 12 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6746 d 12 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.

Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().		  
823 6759 d 12 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
821 6759 d 13 h jermar /kernel/trunk/arch/sparc64/src/mm/ Do not add CONFIG_STACK_SIZE to kernel.size.  
820 6759 d 13 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.		  
815 6759 d 23 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
813 6760 d 12 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.		  
793 6761 d 21 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
792 6761 d 21 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
765 6765 d 14 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6765 d 21 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6765 d 23 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
758 6766 d 13 h jermar /kernel/trunk/arch/ sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.
