599 6749 d 21 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
598 6749 d 21 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
595 6750 d 16 h palkovsky /kernel/trunk/ Fixed bug in vm.c that turned off preemption. Found in versions 390:391.  
594 6750 d 16 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
573 6751 d 17 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
569 6752 d 13 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
548 6754 d 16 h jermar /kernel/trunk/ Cleanup and fixes.  
536 6756 d 14 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6756 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6756 d 16 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 6756 d 16 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6768 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6769 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 6804 d 12 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 6811 d 15 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6814 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 6815 d 2 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6815 d 23 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 6816 d 14 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.		  
394 6816 d 14 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)
