403 6815 d 20 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6818 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).		  
397 6819 d 7 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6820 d 4 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 6820 d 19 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.		  
394 6820 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)		  
391 6821 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 6822 d 5 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().		  
376 6831 d 0 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!		  
368 6835 d 3 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
364 6836 d 6 h palkovsky /SPARTAN/trunk/ Added support for msim with 4kc instructions.
Fixed support for upstream msim.

Small boot fix on Indy.		  
363 6836 d 19 h jermar /SPARTAN/trunk/arch/ Fix copyright notices.  
361 6836 d 20 h bondari /SPARTAN/trunk/ Memory routines per-arch declations for future implementation  
345 6843 d 20 h palkovsky /SPARTAN/trunk/arch/mips32/include/  
344 6843 d 20 h palkovsky /SPARTAN/trunk/ Added more code to arc.
Fixed bad name in byteorder.h		  
342 6844 d 3 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
341 6844 d 3 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
339 6845 d 1 h palkovsky /SPARTAN/trunk/arch/mips/ Make the objcopy files compatibile with gnu-sgi-irix linker.  
338 6845 d 1 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.		  
334 6845 d 3 h jermar /SPARTAN/trunk/arch/ Cleanup.
Cancel __fake in pm.c and replace it with LONG(0xdeadbeaf) in linker script. Still need some to find out why it must be there.
Remove comment saying, that mips is little-endian.
