893 6745 d 9 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.		  
892 6746 d 5 h vana /kernel/trunk/ Itanium active keyboard  
889 6746 d 8 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
884 6746 d 9 h decky /kernel/trunk/arch/ppc32/ move ppc boot loader to /boot tree  
883 6746 d 10 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.		  
881 6746 d 10 h decky /kernel/trunk/arch/ppc32/boot/ PPC32 boot loader preparation  
879 6747 d 2 h vana /kernel/trunk/arch/ia64/ Itanium kernel page extended to maximum (256M) repaired RR manipulation functions, paging setuping function and added some comments.  
878 6747 d 8 h vana /kernel/trunk/ Active keyboard read for ia32  
877 6748 d 2 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.		  
873 6748 d 10 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.		  
872 6749 d 21 h vana /kernel/trunk/ Init stack base fix
Removing commented code		  
871 6749 d 21 h vana /kernel/trunk/arch/ia64/include/ C version of Itanium FADDR()  
870 6749 d 22 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6749 d 22 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
868 6750 d 7 h jermar /kernel/trunk/arch/sparc64/src/mm/ Add missing file.  
867 6750 d 7 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 6750 d 22 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6750 d 22 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
861 6751 d 8 h jermar /kernel/trunk/arch/sparc64/include/ Add atomic_add() operation for sparc64.  
860 6751 d 22 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
854 6753 d 3 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
853 6754 d 6 h palkovsky /kernel/trunk/arch/mips32/ Some arc bios tweaks. Wanted to print configuration data, but
the ARC seems to return strange values.
Newport graphics card does not seem to be easy to port, give up now.		  
852 6754 d 7 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)		  
851 6755 d 0 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6755 d 0 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6755 d 0 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
847 6755 d 3 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6755 d 5 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
845 6755 d 10 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
844 6756 d 1 h palkovsky /kernel/trunk/arch/ppc32/ Added missing CONFIG_FB for ppc.  
843 6756 d 1 h palkovsky /kernel/trunk/ Made powerpc to get on PearPC to the version print when compiled with -O1:
- create proper memory zones
- switch to real mode on boot
TODO
- kernel relocation during boot
- autodetection of framebuffer settings (PCI?) - now includes hardcoded
settings for PearPc.		  
840 6757 d 8 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
838 6758 d 11 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6758 d 11 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6758 d 22 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
833 6759 d 21 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
832 6761 d 23 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6762 d 5 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).		  
830 6762 d 7 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
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().		  
827 6762 d 22 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.
