534 6734 d 18 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6734 d 19 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6746 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6747 d 16 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
 
483 6754 d 18 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.
 
475 6759 d 0 h jermar /SPARTAN/trunk/ Define atomic_t type.  
413 6782 d 14 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
 
401 6792 d 4 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6792 d 4 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.
 
399 6792 d 15 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB exceptions seem to be working on at least simics.
msim handles TLB Refill and TLB Invalid exceptions well,
but seems to skip writes to the mapped addressies in mm
mapping test #1 (the data is not written and exception
is not triggered).
 
397 6793 d 4 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
 
396 6794 d 1 h jermar /SPARTAN/trunk/ Add mm/mapping1 test.
(Will not make it past TLB Invalid exception on mips32.)
Fixes in asid.c.
Make TLB register types union with __u32 value.
Implement tlb_invalidate() for mips32.
(TLB invalidation and shootdown path will have to be revised.)
 
329 6819 d 20 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
326 6820 d 13 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 6825 d 3 h palkovsky /SPARTAN/trunk/ More logical fpu_context_engaged setting.
The sse1 test now correctly tests for thread migration settings.
 
295 6825 d 3 h palkovsky /SPARTAN/trunk/ Test that really tests SSE context switching.  
283 6826 d 5 h palkovsky /SPARTAN/trunk/ IA32 printf-double support migrated to amd64  
266 6827 d 0 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
264 6827 d 1 h cejka /SPARTAN/trunk/ E option in printf added.  
263 6827 d 1 h palkovsky /SPARTAN/trunk/test/synch/rwlock2/ Bad prototype  
228 6828 d 23 h cejka /SPARTAN/trunk/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.
 
225 6829 d 2 h jermar /SPARTAN/trunk/test/synch/rwlock4/ Revert the change in rwlock #4 test that added cpu_priority_high() and cpu_priority_restore() to random().
It is no longer necessary because spinlock disables preemption at least.
 
205 6830 d 4 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().
 
195 6830 d 18 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
 
187 6831 d 1 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.
 
183 6831 d 4 h cejka /SPARTAN/trunk/ Small improvements in print1 test and its source code format.  
182 6831 d 5 h cejka /SPARTAN/trunk/ Test for printf added.  
171 6837 d 2 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

Make rwlock test #4 preemption-safe.

Prepare for preemption controlling functions.
 
125 6876 d 16 h jermar /SPARTAN/trunk/ Huge indentation fix.  
119 6892 d 17 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.
 
111 6915 d 18 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 6932 d 16 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 6932 d 21 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 6933 d 15 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 6933 d 18 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 6934 d 0 h jermar /SPARTAN/trunk/test/fpu/fpu0/ Add check for infinite loops in e().  
88 6934 d 1 h jermar /SPARTAN/trunk/ Rename test/fpu/fp0 to test/fpu/fpu0.
(Couldn't do it in one go.)
 
87 6934 d 1 h jermar /SPARTAN/trunk/ Rename test/fp to test/fpu.  
86 6934 d 1 h jermar /SPARTAN/trunk/test/fp/fp0/ Add BSD license and copyright line.
Coding style and small improvements.
 
84 6934 d 2 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.
