863 6689 d 17 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
862 6689 d 22 h palkovsky /kernel/trunk/genarch/src/fb/ Added logo for framebuffer (simple bitmap)  
861 6690 d 3 h jermar /kernel/trunk/arch/sparc64/include/ Add atomic_add() operation for sparc64.  
860 6690 d 16 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
859 6690 d 16 h decky /kernel/trunk/tools/ make gencontext portable  
858 6690 d 17 h cejka /uspace/trunk/softfloat/generic/ Fix float32 -> unsigned long conversion.  
857 6690 d 17 h cejka /uspace/trunk/softfloat/ Conversion functions from float to int added.
Files arch.h and types.h from arch subdirectory should be replaced later with equivalent files from libc.		  
856 6691 d 19 h bondari /kernel/trunk/generic/include/  
855 6691 d 22 h bondari /kernel/trunk/generic/include/ ELF section definition  
854 6691 d 22 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
853 6693 d 1 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 6693 d 1 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 6693 d 19 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6693 d 19 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6693 d 19 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
848 6693 d 19 h palkovsky /uspace/trunk/ Added userspace for MIPS32-Big endian.  
847 6693 d 22 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6693 d 23 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
845 6694 d 4 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
844 6694 d 20 h palkovsky /kernel/trunk/arch/ppc32/ Added missing CONFIG_FB for ppc.  
843 6694 d 20 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 6695 d 3 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
841 6695 d 4 h jermar /kernel/trunk/contrib/arch/ Add workaround utility for buggy ELF loader in HP Ski IA-64 simulator.  
840 6696 d 3 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
839 6697 d 0 h palkovsky /kernel/trunk/genarch/src/fb/ Better structure for framebuffer.  
838 6697 d 5 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6697 d 6 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6697 d 17 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
835 6697 d 17 h cejka /uspace/trunk/softfloat/generic/ Fixed bugs in 64bit float division.  
834 6697 d 20 h cejka /uspace/trunk/softfloat/generic/ Fixed most problems with 64bit arithmetic (but division is still buggy).  
833 6698 d 15 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
832 6700 d 17 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6701 d 0 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 6701 d 2 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().		  
829 6701 d 2 h cejka /uspace/trunk/softfloat/ Fixed some problems with 64 bit arithmetic but others still persisting.  
828 6701 d 13 h cejka /uspace/trunk/softfloat/ 64bit float division added.
Some bugs fixed in 64bit multiplication and adding.		  
827 6701 d 17 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
826 6701 d 18 h jermar /kernel/trunk/ Add page_mapping_remove().  
825 6701 d 23 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.		  
824 6702 d 7 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.
