924 6813 d 11 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
717 6869 d 2 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
534 6911 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6911 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6923 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
389 6972 d 9 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().		  
341 6994 d 6 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
332 6995 d 7 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.		  
329 6996 d 3 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
326 6996 d 19 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.		  
319 6999 d 10 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
314 6999 d 21 h palkovsky /SPARTAN/trunk/ Small cleanups  
313 6999 d 21 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.		  
205 7006 d 10 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
124 7053 d 0 h decky /SPARTAN/trunk/arch/mips/ fix EXC_Mod define

enhance interrupt handling		  
105 7095 d 20 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.		  
59 7118 d 20 h jermar /SPARTAN/trunk/ Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().

More complete and *almost* functional versions of IA-64 context_save() and context_restore().		  
50 7121 d 5 h jermar /SPARTAN/trunk/ Big indentation update.

Add Jakub Vana to AUTHORS.

Minor fixes.		  
1 7200 d 3 h jermar /SPARTAN/ Initial import
