399 6973 d 19 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 6974 d 6 h jermar /SPARTAN/trunk/ Add arch directory for sparc64.  
397 6974 d 8 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6975 d 5 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 6975 d 20 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.		  
394 6975 d 21 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 6975 d 22 h bondari /SPARTAN/trunk/arch/ia32/include/ Comments fixed  
392 6975 d 22 h bondari /SPARTAN/trunk/arch/ia32/ Last inline functions for IA-32  
391 6976 d 20 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.		  
390 6976 d 20 h bondari /SPARTAN/trunk/arch/ia32/ ia-32 memcmp inline  
389 6977 d 7 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().		  
388 6978 d 5 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Map interrupt vectors to their names.		  
387 6979 d 0 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.  
386 6979 d 1 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for mutex.c.  
385 6979 d 1 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for rwlock.c.  
384 6979 d 2 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for semaphore.c.  
383 6979 d 3 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for spinlock.c.  
382 6979 d 19 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for waitq.c.  
381 6981 d 19 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.		  
380 6981 d 22 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.
