877 6666 d 9 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.		  
873 6666 d 17 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.		  
872 6668 d 5 h vana /kernel/trunk/ Init stack base fix
Removing commented code		  
871 6668 d 5 h vana /kernel/trunk/arch/ia64/include/ C version of Itanium FADDR()  
870 6668 d 5 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6668 d 5 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
868 6668 d 14 h jermar /kernel/trunk/arch/sparc64/src/mm/ Add missing file.  
867 6668 d 14 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.		  
866 6668 d 18 h jermar /kernel/trunk/generic/include/ Remove nasty ppc32 hack.
ppc32 now uses the stock ALIGN_UP().		  
864 6669 d 6 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6669 d 6 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
862 6669 d 11 h palkovsky /kernel/trunk/genarch/src/fb/ Added logo for framebuffer (simple bitmap)  
861 6669 d 16 h jermar /kernel/trunk/arch/sparc64/include/ Add atomic_add() operation for sparc64.  
860 6670 d 5 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
859 6670 d 6 h decky /kernel/trunk/tools/ make gencontext portable  
856 6671 d 9 h bondari /kernel/trunk/generic/include/  
855 6671 d 11 h bondari /kernel/trunk/generic/include/ ELF section definition  
854 6671 d 11 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
853 6672 d 14 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 6672 d 15 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 6673 d 8 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6673 d 8 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6673 d 8 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
847 6673 d 11 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6673 d 12 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
845 6673 d 18 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
844 6674 d 9 h palkovsky /kernel/trunk/arch/ppc32/ Added missing CONFIG_FB for ppc.  
843 6674 d 9 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.		  
842 6674 d 16 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
841 6674 d 17 h jermar /kernel/trunk/contrib/arch/ Add workaround utility for buggy ELF loader in HP Ski IA-64 simulator.  
840 6675 d 16 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
839 6676 d 14 h palkovsky /kernel/trunk/genarch/src/fb/ Better structure for framebuffer.  
838 6676 d 18 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6676 d 19 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6677 d 6 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
833 6678 d 4 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
832 6680 d 7 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6680 d 13 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 6680 d 15 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 6681 d 6 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.
