727	6710 d 1 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
715	6714 d 6 h	vana	/kernel/trunk/arch/ia64/	VHPT setup to be able to use ttag and thash instructions
710	6714 d 8 h	vana	/kernel/trunk/arch/ia64/include/mm/	VHPT entry
703	6716 d 11 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().
699	6719 d 10 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
691	6721 d 7 h	jermar	/kernel/trunk/arch/	Cleanup.
684	6721 d 9 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.
569	6752 d 1 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
537	6755 d 7 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
534	6756 d 4 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6756 d 4 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6768 d 9 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
391	6817 d 2 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	6817 d 12 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().
169	6862 d 1 h	jermar	/SPARTAN/trunk/arch/	For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().
147	6892 d 9 h	jermar	/SPARTAN/trunk/arch/	Add missing memory_init.h files for IA-64 and MIPS architectures. Fix typo in IA-32's memory_init.h.
125	6898 d 2 h	jermar	/SPARTAN/trunk/	Huge indentation fix.
121	6899 d 2 h	jermar	/SPARTAN/trunk/	Begin MIPS implementation of 4-level page table interface. Add email address to each item in doc/AUTHORS. Correct type names in comments in mm/vm.c. Introduce ptl0 pointer in vm_t.
120	6913 d 0 h	jermar	/SPARTAN/trunk/	Generic 4-level page tables interface & implementation (review & test). Implement more architecture dependant macros on IA-32. Provide fake implementation on IA-64 and MIPS. Convert map_page_to_frame() to use the new interface. Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.
105	6941 d 0 h	jermar	/SPARTAN/trunk/	Big changes in IA-32 address space map. Now the kernel is mapped above 0x80000000. Finally! Userspace address space starts at 0x00000000. Changes in many places. This improvement temporarily breaks SMP and most likely also other stuff. Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32. Changes in linker script. Changes required because of the above. Do not patch hardcoded_* variables but assign to them instead. Cosmetic changes here and there.
