864 6667 d 18 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6667 d 18 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
862 6668 d 0 h palkovsky /kernel/trunk/genarch/src/fb/ Added logo for framebuffer (simple bitmap)  
861 6668 d 4 h jermar /kernel/trunk/arch/sparc64/include/ Add atomic_add() operation for sparc64.  
860 6668 d 17 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
859 6668 d 18 h decky /kernel/trunk/tools/ make gencontext portable  
858 6668 d 18 h cejka /uspace/trunk/softfloat/generic/ Fix float32 -> unsigned long conversion.  
857 6668 d 18 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 6669 d 21 h bondari /kernel/trunk/generic/include/  
855 6669 d 23 h bondari /kernel/trunk/generic/include/ ELF section definition  
854 6669 d 23 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
853 6671 d 2 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 6671 d 3 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 6671 d 20 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6671 d 20 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6671 d 20 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
848 6671 d 20 h palkovsky /uspace/trunk/ Added userspace for MIPS32-Big endian.  
847 6671 d 23 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6672 d 0 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
845 6672 d 6 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
844 6672 d 21 h palkovsky /kernel/trunk/arch/ppc32/ Added missing CONFIG_FB for ppc.  
843 6672 d 21 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 6673 d 4 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
841 6673 d 5 h jermar /kernel/trunk/contrib/arch/ Add workaround utility for buggy ELF loader in HP Ski IA-64 simulator.  
840 6674 d 4 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
839 6675 d 2 h palkovsky /kernel/trunk/genarch/src/fb/ Better structure for framebuffer.  
838 6675 d 6 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6675 d 7 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6675 d 18 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
835 6675 d 18 h cejka /uspace/trunk/softfloat/generic/ Fixed bugs in 64bit float division.  
834 6675 d 21 h cejka /uspace/trunk/softfloat/generic/ Fixed most problems with 64bit arithmetic (but division is still buggy).  
833 6676 d 16 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
832 6678 d 19 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6679 d 1 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 6679 d 3 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 6679 d 4 h cejka /uspace/trunk/softfloat/ Fixed some problems with 64 bit arithmetic but others still persisting.  
828 6679 d 15 h cejka /uspace/trunk/softfloat/ 64bit float division added.
Some bugs fixed in 64bit multiplication and adding.		  
827 6679 d 18 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
826 6679 d 19 h jermar /kernel/trunk/ Add page_mapping_remove().
