569 6733 d 12 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
534 6737 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6737 d 15 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6749 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6750 d 13 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
 
413 6785 d 11 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.
 
403 6792 d 15 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6795 d 12 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 6796 d 1 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
 
396 6796 d 22 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 6797 d 13 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.
 
394 6797 d 13 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 6798 d 13 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 6799 d 0 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().
 
341 6820 d 21 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
332 6821 d 22 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.
 
324 6823 d 21 h palkovsky /SPARTAN/trunk/ MIPS architecture now works without any problems in
- msim: compile as OUTPUT_FORMAT(binary)
- gxemul: compile as OUTPUT_FORMAT(ecoff-littlemips), or create
configuration file for binary format (will be done later)
- simics: compile as OUTPUT_FORMAT(elf32-little), might work with binary
format, didn't try yet.
 
319 6826 d 1 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
317 6826 d 1 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
306 6827 d 2 h palkovsky /SPARTAN/trunk/ Fixed mips boot process.
On interrupt saving registers, save $lo, $hi.
Add interrupt naming to asm files (mips).
Save only necessary registers on context switch (see mips ABI).
Fixed copyright info.
