1780 6694 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1658 6720 d 15 h vana /kernel/trunk/test/ Detaching threads in tests  
1196 6773 d 10 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1104 6798 d 6 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.
 
1062 6804 d 1 h jermar /kernel/trunk/ It is now possible to associate symbolic names with both threads and tasks.
More verbose kconsole threads, tasks and scheduler commands.
 
1053 6804 d 6 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1023 6805 d 5 h vana /kernel/trunk/ Itanium FPU active context switch  
1020 6805 d 6 h vana /kernel/trunk/test/fpu/fpu1/ () patch for FPU 1 test  
827 6839 d 0 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 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6918 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6926 d 3 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.
 
329 6991 d 6 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
326 6991 d 22 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.
 
296 6996 d 12 h palkovsky /SPARTAN/trunk/ More logical fpu_context_engaged setting.
The sse1 test now correctly tests for thread migration settings.
 
295 6996 d 12 h palkovsky /SPARTAN/trunk/ Test that really tests SSE context switching.  
283 6997 d 14 h palkovsky /SPARTAN/trunk/ IA32 printf-double support migrated to amd64  
125 7048 d 1 h jermar /SPARTAN/trunk/ Huge indentation fix.  
119 7064 d 2 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.
 
111 7087 d 3 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 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 6 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 7105 d 0 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 7105 d 3 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 7105 d 9 h jermar /SPARTAN/trunk/test/fpu/fpu0/ Add check for infinite loops in e().  
88 7105 d 10 h jermar /SPARTAN/trunk/ Rename test/fpu/fp0 to test/fpu/fpu0.
(Couldn't do it in one go.)
 
87 7105 d 10 h jermar /SPARTAN/trunk/ Rename test/fp to test/fpu.  
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.
