889 6719 d 17 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
883 6719 d 18 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 6721 d 10 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.		  
873 6721 d 18 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.		  
867 6723 d 15 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 6724 d 7 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6724 d 7 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
861 6724 d 17 h jermar /kernel/trunk/arch/sparc64/include/ Add atomic_add() operation for sparc64.  
860 6725 d 6 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
847 6728 d 12 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6728 d 14 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
815 6737 d 17 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
792 6739 d 16 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
765 6743 d 9 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6743 d 15 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6743 d 18 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 6744 d 7 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.		  
757 6744 d 9 h jermar /kernel/trunk/ Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.		  
756 6745 d 6 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.		  
753 6746 d 14 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.
