501 6750 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6750 d 17 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 6757 d 20 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 6762 d 1 h jermar /SPARTAN/trunk/ Define atomic_t type.  
413 6785 d 16 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 6795 d 6 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6795 d 6 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6795 d 16 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 6796 d 6 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6797 d 3 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 6822 d 22 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
326 6823 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.		  
296 6828 d 4 h palkovsky /SPARTAN/trunk/ More logical fpu_context_engaged setting.
The sse1 test now correctly tests for thread migration settings.		  
295 6828 d 4 h palkovsky /SPARTAN/trunk/ Test that really tests SSE context switching.  
283 6829 d 6 h palkovsky /SPARTAN/trunk/ IA32 printf-double support migrated to amd64  
266 6830 d 1 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
264 6830 d 2 h cejka /SPARTAN/trunk/ E option in printf added.  
263 6830 d 3 h palkovsky /SPARTAN/trunk/test/synch/rwlock2/ Bad prototype  
228 6832 d 0 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 6832 d 4 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.
