1096 6615 d 2 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall		  
958 6621 d 20 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
924 6623 d 7 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
906 6632 d 16 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared		  
827 6653 d 17 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
546 6718 d 21 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
534 6720 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6720 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6733 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
341 6804 d 2 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
326 6806 d 15 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.		  
309 6810 d 6 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
103 6907 d 21 h jermar /SPARTAN/trunk/ Just cleanup.  
92 6918 d 23 h jermar /SPARTAN/trunk/ FPU work.
FPU code cleanup, add/fix copyright notices where needed.
Fix PI calculation to use double n instead of int n.
Make FPU test #1 even more stressing.

Re-enable O3 again.
Revert Makefile.config not to compile in any tests.		  
57 6930 d 16 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
52 6930 d 18 h vana /SPARTAN/trunk/ Move fpu_context switching functions from context.s to fpu_context.c on all platforms.
Add fpu_context.h.

Make before_thread_runs() arch-independent and create arch dependent version before_thread_runs_arch().
