703	6687 d 21 h	jermar	/kernel/trunk/	Memory management work. - vm.* -> as.* (as like address space is, imho, more fitting) - Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid(). - Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault(). - Add high-level page fault handler as_page_fault(). - Add as_area_load_mapping().
687	6692 d 18 h	jermar	/kernel/trunk/	Memory management work. Pass address space identifier to functions in page_operations to support single global page hash table.
618	6718 d 11 h	jermar	/kernel/trunk/arch/mips32/src/mm/	Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.
612	6719 d 14 h	jermar	/kernel/trunk/arch/mips32/src/mm/	Weaken the assumption, that PageMask register contains the right mask everytime. As a result, TLB exceptions will explicitly write this register when filling TLB entry. Adjust tlb_print() on mips32 to print PageMask as well.
599	6720 d 20 h	jermar	/kernel/trunk/arch/mips32/	Fixes for mips32 invalidation functions.
598	6720 d 20 h	jermar	/kernel/trunk/arch/mips32/src/mm/	TLB invalidation functions for mips32. Not deployed yet. Not tested.
594	6721 d 15 h	jermar	/kernel/trunk/	ptlb command (currently usable on mips32 only).
569	6723 d 11 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
534	6727 d 14 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6727 d 15 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6739 d 19 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6740 d 12 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	6775 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	6782 d 14 h	jermar	/SPARTAN/trunk/arch/	Small improvement in pte_t type definition.
399	6785 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).
397	6786 d 0 h	jermar	/SPARTAN/trunk/	Small changes to mips32 mm. Small changes in mm mapping test #1.
396	6786 d 21 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	6787 d 12 h	jermar	/SPARTAN/trunk/arch/mips32/src/mm/	Small fix. MIPS32 pte_t.c is not bool.
394	6787 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	6788 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.
