598 6740 d 10 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
595 6741 d 4 h palkovsky /kernel/trunk/ Fixed bug in vm.c that turned off preemption. Found in versions 390:391.  
594 6741 d 5 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
573 6742 d 6 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
569 6743 d 2 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
548 6745 d 5 h jermar /kernel/trunk/ Cleanup and fixes.  
536 6747 d 3 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6747 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6747 d 5 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6747 d 5 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6759 d 9 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6760 d 2 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 6795 d 1 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 6802 d 4 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6805 d 1 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 6805 d 14 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6806 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 6807 d 3 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.		  
394 6807 d 3 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 6808 d 2 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.
