747	6694 d 5 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	6694 d 14 h	jermar	/kernel/trunk/	Page hash table modifications.
741	6696 d 7 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	6696 d 13 h	jermar	/kernel/trunk/	ia64 ASID management code (not tested).
730	6699 d 10 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6701 d 5 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
715	6705 d 10 h	vana	/kernel/trunk/arch/ia64/	VHPT setup to be able to use ttag and thash instructions
710	6705 d 12 h	vana	/kernel/trunk/arch/ia64/include/mm/	VHPT entry
703	6707 d 15 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	6710 d 14 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
691	6712 d 11 h	jermar	/kernel/trunk/arch/	Cleanup.
684	6712 d 13 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	6743 d 5 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
537	6746 d 11 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	6747 d 8 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6747 d 8 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6759 d 13 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
391	6808 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	6808 d 16 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	6853 d 6 h	jermar	/SPARTAN/trunk/arch/	For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().
