418 6793 d 3 h jermar /SPARTAN/trunk/ sparc64 infrastructure.  
417 6796 d 9 h palkovsky /SPARTAN/trunk/arch/amd64/src/boot/ Added identity mapping for more then 16MB - now it maps 64MB on boot.  
416 6796 d 10 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Put RSE into lazy mode before writing ar.bspstore and ar.rnat.
Flush RSE before setting ar.bspstore so that ar.bsp is set to the same address.		  
415 6796 d 11 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 6797 d 14 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 6798 d 0 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 6798 d 14 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 6799 d 4 h jermar /SPARTAN/trunk/ Doxygen comments.  
410 6799 d 4 h jermar /SPARTAN/trunk/ Doxygen-style comments.  
409 6799 d 14 h jermar /SPARTAN/trunk/contrib/toolchain/ sparc64 toolchain build script.  
408 6800 d 10 h decky /SPARTAN/trunk/ IA32 has_cpuid() inline
minor indentation fixes		  
407 6800 d 10 h decky /SPARTAN/trunk/ fix shell warning  
406 6803 d 2 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 6804 d 3 h jermar /SPARTAN/trunk/src/ Doxygen comments fixes.  
404 6804 d 3 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
403 6805 d 3 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
402 6805 d 12 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 6807 d 14 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6807 d 14 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6808 d 0 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 6808 d 12 h jermar /SPARTAN/trunk/ Add arch directory for sparc64.  
397 6808 d 14 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6809 d 11 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 6810 d 2 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.		  
394 6810 d 2 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 6810 d 4 h bondari /SPARTAN/trunk/arch/ia32/include/ Comments fixed  
392 6810 d 4 h bondari /SPARTAN/trunk/arch/ia32/ Last inline functions for IA-32  
391 6811 d 1 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 6811 d 2 h bondari /SPARTAN/trunk/arch/ia32/ ia-32 memcmp inline  
389 6811 d 12 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 6812 d 10 h jermar /SPARTAN/trunk/arch/ia64/src/ IA-64 work.
Map interrupt vectors to their names.		  
387 6813 d 5 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.

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

Small changes elsewhere.		  
380 6816 d 3 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.
