1229	6776 d 14 h	jermar	/kernel/trunk/	Remove the outdated TODO file. Improve doxygen comments here and there.
1221	6778 d 4 h	decky	/kernel/trunk/	printf-related and other code cleanup
1044	6815 d 14 h	jermar	/kernel/trunk/	Page table locking.
826	6850 d 5 h	jermar	/kernel/trunk/	Add page_mapping_remove().
793	6853 d 12 h	jermar	/kernel/trunk/	Use hash_table_get_instance instead of list_get_instance. Rename page_operations to page_mapping_operations. Rename page_pt_operations to pt_mapping_operations. Rename page_ht_operations to ht_mapping_operations.
756	6859 d 3 h	jermar	/kernel/trunk/	Memory management work. Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find(). Page table address is now extracted from the first (i.e. 'as') argument. Add a lot of infrastructure to make the above possible. sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
755	6860 d 2 h	jermar	/kernel/trunk/	Change page_mapping_find/insert interfaces to take as_t * as first argument and not asid_t as second argument. This change was necessitated by the removal of mapping array from as_area_t and the fact that an address space doesn't have an ASID when it is created.
703	6877 d 14 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	6880 d 14 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
687	6882 d 11 h	jermar	/kernel/trunk/	Memory management work. Pass address space identifier to functions in page_operations to support single global page hash table.
684	6882 d 12 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.
654	6901 d 9 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.
548	6915 d 7 h	jermar	/kernel/trunk/	Cleanup and fixes.
534	6917 d 8 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
533	6917 d 8 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	6917 d 8 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6929 d 12 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6930 d 5 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.
430	6950 d 5 h	jermar	/SPARTAN/trunk/	Move src/ and include/ to generic.
391	6978 d 5 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.
