501	6757 d 13 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6758 d 6 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.
489	6764 d 12 h	jermar	/SPARTAN/trunk/generic/	Make the buddy system more general. Store implementation defined pointer in buddy_system_t. Pass buddy system pointer to implementation defined buddy system operations.
482	6766 d 9 h	jermar	/SPARTAN/trunk/generic/include/	Fix typo in buddy.h. Make default memsize 8M.
480	6767 d 8 h	bondari	/SPARTAN/trunk/generic/	Buddy system allocator implementation. Not checked. For review only.
479	6768 d 9 h	bondari	/SPARTAN/trunk/generic/	Buddy system implementation. Not functional yet - only framework prepeared. Also added 2 macros FRAME2ADDR and ADDR2FRAME.
458	6771 d 16 h	decky	/SPARTAN/trunk/	make configuration variables usage consistent
440	6773 d 11 h	jermar	/SPARTAN/trunk/generic/include/mm/	Add some comments for buddy system operations.
430	6778 d 6 h	jermar	/SPARTAN/trunk/	Move src/ and include/ to generic.
396	6804 d 15 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.)
391	6806 d 6 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	6806 d 17 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().
381	6811 d 5 h	jermar	/SPARTAN/trunk/	Make cross-compiler the default compiler on IA-32. For native compilations, use ./build.ia32 native. Small changes elsewhere.
378	6812 d 15 h	jermar	/SPARTAN/trunk/	Redeclare eraly_malloc() with __attribute__ ((malloc)) to improve optimizations. Reorganize #include's in scheduler.c. Buddy system improvements. Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced. Add some assertions.
377	6815 d 8 h	jermar	/SPARTAN/trunk/	Generic buddy allocator. Please review the code before it is deployed.
374	6817 d 5 h	jermar	/SPARTAN/trunk/	Revert previous change in frame_t as it broke IA-64. (Most likely some alignment problem.) Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively. Define new macros malloc() and free(). They are to be replaced by real functions some day.
373	6817 d 7 h	jermar	/SPARTAN/trunk/	Physical memory management work. Add "__attribute__ ((packed))" to frame_t so that it takes up less space. Note that this is essential as there is lot of these structures. Remove busy list from zone_t as it is redundant.
368	6819 d 15 h	jermar	/SPARTAN/trunk/	Physical memory management work. New frame allocator. Some architectures need to have bigger heap.
367	6820 d 5 h	jermar	/SPARTAN/trunk/	Physical memory management work. Implement zone_() and some frame_() functions.
366	6820 d 6 h	jermar	/SPARTAN/trunk/include/	Add zone pointer to frame_t. This will be essential for fast frame_free(). Rename frame_zone_t to zone_t. Declare frame and zone functions to be implemented.
