599	6912 d 5 h	jermar	/kernel/trunk/arch/mips32/	Fixes for mips32 invalidation functions.
598	6912 d 5 h	jermar	/kernel/trunk/arch/mips32/src/mm/	TLB invalidation functions for mips32. Not deployed yet. Not tested.
594	6913 d 0 h	jermar	/kernel/trunk/	ptlb command (currently usable on mips32 only).
569	6914 d 21 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
534	6919 d 0 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6919 d 0 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6931 d 4 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6931 d 21 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	6966 d 20 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	6973 d 23 h	jermar	/SPARTAN/trunk/arch/	Small improvement in pte_t type definition.
399	6976 d 20 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	6977 d 9 h	jermar	/SPARTAN/trunk/	Small changes to mips32 mm. Small changes in mm mapping test #1.
396	6978 d 7 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	6978 d 22 h	jermar	/SPARTAN/trunk/arch/mips32/src/mm/	Small fix. MIPS32 pte_t.c is not bool.
394	6978 d 22 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	6979 d 21 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	6980 d 8 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	7002 d 6 h	jermar	/SPARTAN/trunk/	Rename mips port to mips32.
332	7003 d 7 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	7005 d 5 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.
