1023 6812 d 2 h vana /kernel/trunk/ Itanium FPU active context switch  
1020 6812 d 3 h vana /kernel/trunk/test/fpu/fpu1/ () patch for FPU 1 test  
827 6845 d 21 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
534 6913 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6913 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6925 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6933 d 1 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
283 7004 d 11 h palkovsky /SPARTAN/trunk/ IA32 printf-double support migrated to amd64  
125 7054 d 22 h jermar /SPARTAN/trunk/ Huge indentation fix.  
119 7071 d 0 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.
 
111 7094 d 0 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.
 
94 7110 d 23 h jermar /SPARTAN/trunk/ IA-64 work.
Add application registers ar.lc, ar.ec, ar.ccv, ar.csd, ar.ssd to context_t.
Add store/load operations for ar.lc, ar.ec, ar.ccv, ar.csd, ar.ssd to context_save()/restore().
Add application registers ar.rcs, ar.bsp and ar.rnat to context_t.
Proper store/load operations for ar.rcs, ar.bsp and ar.rnat is in the works.

FPU cleanup.
Remove call set_TS_flag() from cpu_identify().
Remove unneeded includes from FPU test #1.
 
92 7111 d 3 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.
 
91 7111 d 21 h jermar /SPARTAN/trunk/ Rename test/fpu/fpu0 to test/fpu/fpu1.
Enhance and beautify FPU test #1.
Add pi calculation to FPU test #1.
 
90 7112 d 0 h vana /SPARTAN/trunk/ Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.
Optimalization on IA-32 disabled.
 
89 7112 d 7 h jermar /SPARTAN/trunk/test/fpu/fpu0/ Add check for infinite loops in e().  
88 7112 d 7 h jermar /SPARTAN/trunk/ Rename test/fpu/fp0 to test/fpu/fpu0.
(Couldn't do it in one go.)
 
87 7112 d 7 h jermar /SPARTAN/trunk/ Rename test/fp to test/fpu.  
86 7112 d 7 h jermar /SPARTAN/trunk/test/fp/fp0/ Add BSD license and copyright line.
Coding style and small improvements.
 
84 7112 d 9 h vana /SPARTAN/trunk/ IA-32 FPU lazy context switching.
Doesn't work on Bochs and sometimes produces wrong results on P4.
Seems to work on VMware and PII.

Build script for IA-32 changed to build floppy images (image.bin) 1440K long.
