684	6775 d 15 h	jermar	/kernel/trunk/	Memory management work. Move generic 4-level page table interface to genarch and enable architectures to use different virtual memory mechanisms (e.g. page hash tables). Start page hash table support. Switch ia64 and sparc64 to page hash tables. Other architectures keep on using 4-level page table interface.
683	6775 d 16 h	bondari	/kernel/trunk/generic/	Console command 'zone' now takes zone address as parameter. Added buddy system statistics into the 'zone' command.
677	6779 d 12 h	bondari	/kernel/trunk/generic/src/	Comments to zone console commands
676	6779 d 12 h	bondari	/kernel/trunk/generic/	Memory zones console command implementation. todo: buddy allocator structures.
654	6794 d 13 h	jermar	/kernel/trunk/generic/src/	Fix page_insert_mapping(). Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.
629	6799 d 11 h	decky	/kernel/trunk/	init task loading (yet buggy)
625	6799 d 14 h	palkovsky	/kernel/trunk/	We are now almost -Wall clean. - redefined atomic_t - deleted many, many unused variables - some minor code cleanups found using compiler warning.
624	6799 d 15 h	jermar	/kernel/trunk/generic/	Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.
623	6799 d 20 h	jermar	/kernel/trunk/	Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros. SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations in dynamically allocated structures on which spinlock_initialize() is called after their creation. SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations of global spinlocks. It declares and initializes the spinlock. Moreover, both macros are empty on UP so that -Wall warnings about unused structures get supressed.
615	6801 d 19 h	palkovsky	/kernel/trunk/	Cleanups to make it compile with -Wall. Did not catch everything yet.
596	6804 d 6 h	jermar	/kernel/trunk/	kconsole cleanup. Separate commands from the engine.
594	6804 d 11 h	jermar	/kernel/trunk/	ptlb command (currently usable on mips32 only).
591	6804 d 12 h	palkovsky	/kernel/trunk/generic/src/	Fixes in new console.
590	6804 d 12 h	palkovsky	/kernel/trunk/	Move all MIPS exceptions to generic dispatcher. Align size in malloc() to __native size, some architectures don't like it unaligned.
569	6806 d 8 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
564	6807 d 7 h	jermar	/kernel/trunk/	Send in some improvements.
552	6808 d 8 h	palkovsky	/kernel/trunk/	Named spinlocks
548	6808 d 11 h	jermar	/kernel/trunk/	Cleanup and fixes.
541	6809 d 7 h	jermar	/kernel/trunk/generic/src/mm/	Get rid of junk.
539	6809 d 11 h	jermar	/kernel/trunk/	Buddy allocator cleanup and fixes. - Add some comments. - Update zone information on frames allocation/deallocation.
538	6809 d 12 h	jermar	/kernel/trunk/	Buddy allocator cleanup and fixes II. - Rewrite IS_BUDDY_LEFT_BLOCK so that it does not need floating point on some architectures (e.g. IA-64). - Get rid of IS_BUDDY_RIGHT_BLOCK. - Make sparc64 use zone_create_in_region.
537	6809 d 13 h	jermar	/kernel/trunk/	Buddy system cleanup and fixes. - missing use of KA2PA in frame_init - truncating black list addresses to frame boundaries - removal of left-over obsolete structures - fixing some comments
536	6810 d 9 h	bondari	/kernel/trunk/	Minor bugfix caused by invalid frame_region_not_free() usage
534	6810 d 11 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
533	6810 d 11 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	6810 d 11 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6822 d 15 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6823 d 8 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.
490	6829 d 14 h	jermar	/SPARTAN/trunk/generic/src/mm/	Fix typo and clean up comments.
489	6829 d 14 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.
488	6829 d 20 h	bondari	/SPARTAN/trunk/generic/src/mm/	Small fix :)
487	6829 d 20 h	bondari	/SPARTAN/trunk/generic/src/mm/	Frame isect/coalesce functions optimization
480	6832 d 10 h	bondari	/SPARTAN/trunk/generic/	Buddy system allocator implementation. Not checked. For review only.
479	6833 d 11 h	bondari	/SPARTAN/trunk/generic/	Buddy system implementation. Not functional yet - only framework prepeared. Also added 2 macros FRAME2ADDR and ADDR2FRAME.
458	6836 d 18 h	decky	/SPARTAN/trunk/	make configuration variables usage consistent
430	6843 d 8 h	jermar	/SPARTAN/trunk/	Move src/ and include/ to generic.
413	6858 d 7 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.
391	6871 d 8 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	6871 d 19 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	6876 d 7 h	jermar	/SPARTAN/trunk/	Make cross-compiler the default compiler on IA-32. For native compilations, use ./build.ia32 native. Small changes elsewhere.
