424 6775 d 8 h jermar /SPARTAN/trunk/ sparc64 work.
Link kernel with load address 0x4000.
Add fragment of Linux image header to force SILO to always load the kernel at 0x4000.
Adjust ofw.h and ofw.c to work also on sparc64.		  
423 6777 d 6 h decky /SPARTAN/trunk/ Enable/disable CPU memory barriers at compile time  
422 6778 d 13 h jermar /SPARTAN/trunk/ Move ACPI code to genarch.
Enable it for ia32, amd64 and ia64.
For now, ia64 support is commented out.		  
421 6778 d 22 h jermar /SPARTAN/trunk/ Create genarch directory.
Move ppc32 ofw.[ch] to genarch.
Fix prototype for ofw_call() to return __address instead of int (please review).
Fix copyright notice in sparc64/boot/boot.S.		  
420 6778 d 23 h jermar /SPARTAN/trunk/arch/sparc64/ Small sparc64 changes.
Start native boot loader.		  
419 6780 d 1 h bondari /SPARTAN/trunk/arch/ Memory inline functions for AMD64.
memcmp and memcpy are redefined according to norma		  
418 6782 d 1 h jermar /SPARTAN/trunk/ sparc64 infrastructure.  
417 6785 d 7 h palkovsky /SPARTAN/trunk/arch/amd64/src/boot/ Added identity mapping for more then 16MB - now it maps 64MB on boot.  
416 6785 d 8 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 6785 d 9 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 6786 d 12 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 6786 d 22 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 6787 d 12 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 6788 d 2 h jermar /SPARTAN/trunk/ Doxygen comments.  
410 6788 d 2 h jermar /SPARTAN/trunk/ Doxygen-style comments.  
409 6788 d 12 h jermar /SPARTAN/trunk/contrib/toolchain/ sparc64 toolchain build script.  
408 6789 d 8 h decky /SPARTAN/trunk/ IA32 has_cpuid() inline
minor indentation fixes		  
407 6789 d 8 h decky /SPARTAN/trunk/ fix shell warning  
406 6792 d 0 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 6793 d 1 h jermar /SPARTAN/trunk/src/ Doxygen comments fixes.  
404 6793 d 1 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
403 6794 d 1 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
402 6794 d 10 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 6796 d 12 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6796 d 12 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6796 d 22 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 6797 d 10 h jermar /SPARTAN/trunk/ Add arch directory for sparc64.  
397 6797 d 12 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6798 d 9 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 6799 d 0 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.		  
394 6799 d 0 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 6799 d 2 h bondari /SPARTAN/trunk/arch/ia32/include/ Comments fixed

391 6800 d 0 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 6800 d 0 h bondari /SPARTAN/trunk/arch/ia32/ ia-32 memcmp inline  
389 6800 d 10 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().

Map interrupt vectors to their names.		  
387 6802 d 4 h jermar /SPARTAN/trunk/src/synch/ Doxygen-style comments for condvar.c.
