852	6647 d 20 h	palkovsky	/kernel/trunk/	Fixes in memory allocator - proper kernel blacklisting, when kernel not loaded on page boundary - correct zone adding in zone list (how could this work??)
849	6648 d 13 h	palkovsky	/kernel/trunk/arch/mips32/include/mm/	Fixed mips-big endian TLB problems.
831	6655 d 18 h	jermar	/kernel/trunk/	Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings. This helps to distinguish valid entries from not present entries with 0 content (i.e. not present entries with PFN 0 and other bits cleared).
600	6716 d 19 h	jermar	/kernel/trunk/arch/mips32/	Different sizes of TLB on mips32. R4000 has 48 entries, 4kc has only 16 entries.
599	6716 d 20 h	jermar	/kernel/trunk/arch/mips32/	Fixes for mips32 invalidation functions.
594	6717 d 15 h	jermar	/kernel/trunk/	ptlb command (currently usable on mips32 only).
534	6723 d 15 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6723 d 15 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6735 d 19 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
403	6778 d 14 h	jermar	/SPARTAN/trunk/arch/	Small improvement in pte_t type definition.
399	6781 d 11 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).
396	6782 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.)
394	6783 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	6784 d 12 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	6784 d 23 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	6806 d 21 h	jermar	/SPARTAN/trunk/	Rename mips port to mips32.
319	6812 d 0 h	jermar	/SPARTAN/trunk/arch/mips/	Copyright notices changes.
317	6812 d 1 h	palkovsky	/SPARTAN/trunk/	MIPS exception now saves all necesssary information only on stack.
121	6866 d 12 h	jermar	/SPARTAN/trunk/	Begin MIPS implementation of 4-level page table interface. Add email address to each item in doc/AUTHORS. Correct type names in comments in mm/vm.c. Introduce ptl0 pointer in vm_t.
1	7012 d 17 h	jermar	/SPARTAN/	Initial import
