415 6881 d 17 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 6882 d 20 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 6883 d 6 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 6883 d 20 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 6884 d 10 h jermar /SPARTAN/trunk/ Doxygen comments.  
410 6884 d 10 h jermar /SPARTAN/trunk/ Doxygen-style comments.  
409 6884 d 20 h jermar /SPARTAN/trunk/contrib/toolchain/ sparc64 toolchain build script.  
408 6885 d 16 h decky /SPARTAN/trunk/ IA32 has_cpuid() inline
minor indentation fixes		  
407 6885 d 16 h decky /SPARTAN/trunk/ fix shell warning  
406 6888 d 8 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 6889 d 9 h jermar /SPARTAN/trunk/src/ Doxygen comments fixes.  
404 6889 d 9 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
403 6890 d 9 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
402 6890 d 18 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 6892 d 20 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6892 d 20 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6893 d 6 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 6893 d 18 h jermar /SPARTAN/trunk/ Add arch directory for sparc64.  
397 6893 d 20 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6894 d 17 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 6895 d 8 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.		  
394 6895 d 8 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 6895 d 10 h bondari /SPARTAN/trunk/arch/ia32/include/ Comments fixed  
392 6895 d 10 h bondari /SPARTAN/trunk/arch/ia32/ Last inline functions for IA-32  
391 6896 d 8 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 6896 d 8 h bondari /SPARTAN/trunk/arch/ia32/ ia-32 memcmp inline  
389 6896 d 18 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 6897 d 17 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Map interrupt vectors to their names.		  
387 6898 d 12 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.

385 6898 d 13 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for rwlock.c.  
384 6898 d 14 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for semaphore.c.

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

Small changes elsewhere.		  
380 6901 d 9 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.

Reorganize #include's in scheduler.c.

Buddy system improvements.
Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced.
Add some assertions.		  
377 6905 d 10 h jermar /SPARTAN/trunk/ Generic buddy allocator.
Please review the code before it is deployed.
