1780 6694 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6715 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1019 6805 d 6 h vana /kernel/trunk/arch/ia32/ ia32 MMX and SSEx support  
906 6817 d 22 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 6838 d 23 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
534 6906 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6906 d 3 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6918 d 7 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
309 6995 d 12 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
282 6997 d 14 h palkovsky /SPARTAN/trunk/ Fixed gdtr naming issues after ia32 changes.
Fixed stack alignment on new thread to by multiple of 16,
we are now ABI-correct and we do not #GP on va_arg to boot.
Fixed bad exception register names reporting.
Fixed bad _hardcoded_load_addr, which caused allocation of kernel text
frames.
 
281 6997 d 22 h palkovsky /SPARTAN/trunk/arch/ia32/src/ Fixed some stupid typos.  
257 6998 d 13 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.
 
125 7048 d 0 h jermar /SPARTAN/trunk/ Huge indentation fix.  
94 7104 d 1 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 7104 d 5 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.
 
90 7105 d 2 h vana /SPARTAN/trunk/ Set TS flag on system startup.
Some bugs in FPU context switching seem to persist.
Optimalization on IA-32 disabled.
 
84 7105 d 11 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.
 
80 7107 d 4 h vana /SPARTAN/trunk/ Fix page fault caused by dereferencing NULL pointer.  
75 7112 d 4 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 7113 d 1 h vana /SPARTAN/trunk/ Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK.
 
58 7115 d 22 h vana /SPARTAN/trunk/arch/ia32/ Functions for switching TS flag.  
57 7115 d 23 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
52 7116 d 0 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().
