867 6730 d 6 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 6730 d 10 h jermar /kernel/trunk/generic/include/ Remove nasty ppc32 hack.
ppc32 now uses the stock ALIGN_UP().		  
865 6730 d 10 h cejka /uspace/trunk/softfloat/ Completed conversions from float/double to integer types.  
864 6730 d 21 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6730 d 21 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
862 6731 d 3 h palkovsky /kernel/trunk/genarch/src/fb/ Added logo for framebuffer (simple bitmap)  
861 6731 d 8 h jermar /kernel/trunk/arch/sparc64/include/ Add atomic_add() operation for sparc64.  
860 6731 d 21 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
859 6731 d 21 h decky /kernel/trunk/tools/ make gencontext portable  
858 6731 d 22 h cejka /uspace/trunk/softfloat/generic/ Fix float32 -> unsigned long conversion.  
857 6731 d 22 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 6733 d 0 h bondari /kernel/trunk/generic/include/  
855 6733 d 3 h bondari /kernel/trunk/generic/include/ ELF section definition  
854 6733 d 3 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
853 6734 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 6734 d 6 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 6735 d 0 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6735 d 0 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6735 d 0 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
848 6735 d 0 h palkovsky /uspace/trunk/ Added userspace for MIPS32-Big endian.  
847 6735 d 3 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.  
846 6735 d 4 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Relocate kernel to 4M.		  
845 6735 d 9 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
844 6736 d 0 h palkovsky /kernel/trunk/arch/ppc32/ Added missing CONFIG_FB for ppc.  
843 6736 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.		  
842 6736 d 8 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
841 6736 d 9 h jermar /kernel/trunk/contrib/arch/ Add workaround utility for buggy ELF loader in HP Ski IA-64 simulator.  
840 6737 d 8 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
839 6738 d 5 h palkovsky /kernel/trunk/genarch/src/fb/ Better structure for framebuffer.  
838 6738 d 10 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6738 d 11 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6738 d 22 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
835 6738 d 22 h cejka /uspace/trunk/softfloat/generic/ Fixed bugs in 64bit float division.  
834 6739 d 1 h cejka /uspace/trunk/softfloat/generic/ Fixed most problems with 64bit arithmetic (but division is still buggy).  
833 6739 d 20 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
832 6741 d 22 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6742 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 6742 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().		  
829 6742 d 7 h cejka /uspace/trunk/softfloat/ Fixed some problems with 64 bit arithmetic but others still persisting.  
828 6742 d 18 h cejka /uspace/trunk/softfloat/ 64bit float division added.
Some bugs fixed in 64bit multiplication and adding.
