748	6691 d 14 h	jermar	/kernel/trunk/arch/ia64/	First HT_HASH_ARCH implementation for ia64.
747	6692 d 7 h	jermar	/kernel/trunk/	ia64 work. Add nice wrappers for thash and ttag instructions. Add nice wrappers for accessing reion registers and PTA. Fix set_vhpt_environment(). Allocate and initialize page_ht (a.k.a. VHPT). Add missing header to sparc64. Remove excessive header from debug.h.
746	6692 d 16 h	jermar	/kernel/trunk/	Page hash table modifications.
741	6694 d 10 h	jermar	/kernel/trunk/	Unlock address space prior TLB shootdown in get_asid() to unify the locking order among mips32, sparc64 and ia64. Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64 in a clean way.
740	6694 d 15 h	jermar	/kernel/trunk/	ia64 ASID management code (not tested).
730	6697 d 12 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6699 d 8 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
715	6703 d 12 h	vana	/kernel/trunk/arch/ia64/	VHPT setup to be able to use ttag and thash instructions
710	6703 d 15 h	vana	/kernel/trunk/arch/ia64/include/mm/	VHPT entry
703	6705 d 17 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	6708 d 17 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
691	6710 d 13 h	jermar	/kernel/trunk/arch/	Cleanup.
684	6710 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.
569	6741 d 7 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
537	6744 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
534	6745 d 10 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6745 d 11 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6757 d 15 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
391	6806 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	6806 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().
