Rev	Age	Author	Path	Log message
569	6740 d 6 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
548	6742 d 9 h	jermar	/kernel/trunk/	Cleanup and fixes.
536	6744 d 8 h	bondari	/kernel/trunk/	Minor bugfix caused by invalid frame_region_not_free() usage
534	6744 d 10 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
533	6744 d 10 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	6744 d 10 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6756 d 14 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6757 d 7 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	6792 d 6 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	6799 d 9 h	jermar	/SPARTAN/trunk/arch/	Small improvement in pte_t type definition.
399	6802 d 6 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	6802 d 19 h	jermar	/SPARTAN/trunk/	Small changes to mips32 mm. Small changes in mm mapping test #1.
396	6803 d 16 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	6804 d 8 h	jermar	/SPARTAN/trunk/arch/mips32/src/mm/	Small fix. MIPS32 pte_t.c is not bool.
394	6804 d 8 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	6805 d 7 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	6805 d 18 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().
368	6818 d 16 h	jermar	/SPARTAN/trunk/	Physical memory management work. New frame allocator. Some architectures need to have bigger heap.
341	6827 d 15 h	jermar	/SPARTAN/trunk/	Rename mips port to mips32.
332	6828 d 16 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.
