415 6825 d 3 h jermar /SPARTAN/trunk/arch/ia64/include/ Make context_set() reset ar.pfs.pfm (especially ar.pfs.pfm.sol) so that register stack does not underflow.  
414 6826 d 6 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.		  
413 6826 d 17 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.		  
412 6827 d 7 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
context_save() doesn't have to restore ar.pfs as it is a leaf procedure.
Get rid of assembler warning for start.S.		  
411 6827 d 20 h jermar /SPARTAN/trunk/ Doxygen comments.  
410 6827 d 21 h jermar /SPARTAN/trunk/ Doxygen-style comments.  
409 6828 d 7 h jermar /SPARTAN/trunk/contrib/toolchain/ sparc64 toolchain build script.  
408 6829 d 2 h decky /SPARTAN/trunk/ IA32 has_cpuid() inline
minor indentation fixes		  
407 6829 d 3 h decky /SPARTAN/trunk/ fix shell warning  
406 6831 d 19 h jermar /SPARTAN/trunk/arch/ Fix directives for K_TEXT_START, K_TEXT_START_2 and K_DATA_START sections to be more descriptive about section's content.
Remove LOAD(0xdeadbeaf) from ia32 linker script.
Remove __fake from amd64 pm.c.		  
405 6832 d 19 h jermar /SPARTAN/trunk/src/ Doxygen comments fixes.  
404 6832 d 20 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
403 6833 d 20 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
402 6834 d 5 h jermar /SPARTAN/trunk/ Add ALIGN() macro.

Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review.		  
401 6836 d 6 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6836 d 7 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6836 d 17 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).		  
398 6837 d 4 h jermar /SPARTAN/trunk/ Add arch directory for sparc64.  
397 6837 d 6 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6838 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.)		  
395 6838 d 18 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.		  
394 6838 d 19 h jermar /SPARTAN/trunk/arch/mips32/ MIPS32 memory management work.
Fix some bugs introduced yesterday (PTL3 index is indeed calculated by >> 14).
Introduce two new bits in pte_t (i.e. 'a' and 'w').
Implement TLB Invalid Exception and TLB Modified Exception. (Needs review and testing)		  
393 6838 d 20 h bondari /SPARTAN/trunk/arch/ia32/include/ Comments fixed  
392 6838 d 20 h bondari /SPARTAN/trunk/arch/ia32/ Last inline functions for IA-32  
391 6839 d 18 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.

389 6840 d 5 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.

388 6841 d 3 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Map interrupt vectors to their names.		  
387 6841 d 22 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.

384 6842 d 0 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for semaphore.c.

For native compilations, use ./build.ia32 native.

Small changes elsewhere.		  
380 6844 d 20 h jermar /SPARTAN/trunk/include/ Implement splitting and concatenation for headless doubly-linked circular lists.
This is going to be needed during implementation of buddy system operations for zones.
Add doxygen-style comments to all functions in list.h.

Buddy system improvements.
Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced.
Add some assertions.

Please review the code before it is deployed.
