1411	6751 d 1 h	jermar	/kernel/trunk/	Modify the hierarchy of page fault handlers to pass access mode that caused the fault. Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC to as_page_fault(), depending on the cause of the fault.
1382	6754 d 21 h	decky	/kernel/trunk/	make hardware memory mapping more generic
1288	6770 d 6 h	jermar	/kernel/trunk/	Complete implementation of copy_from_uspace() and copy_to_uspace() for amd64 and ia32. Other architectures still compile and run, but need to implement their own assembly-only memcpy(), memcpy_from_uspace(), memcpy_to_uspace() and their failover parts. For these architectures only dummy implementations are provided.
1044	6820 d 5 h	jermar	/kernel/trunk/	Page table locking.
977	6822 d 4 h	jermar	/kernel/trunk/	Add sys_mremap() syscall.
965	6822 d 9 h	palkovsky	/kernel/trunk/	Added skeleton name service. Cleanup for IPC to use mutexes instead of spinlocks.
955	6822 d 23 h	palkovsky	/kernel/trunk/	Added kernel IPC functionality.
826	6854 d 20 h	jermar	/kernel/trunk/	Add page_mapping_remove().
793	6858 d 3 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	6863 d 18 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	6864 d 18 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.
699	6885 d 5 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
687	6887 d 2 h	jermar	/kernel/trunk/	Memory management work. Pass address space identifier to functions in page_operations to support single global page hash table.
684	6887 d 3 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.
534	6921 d 23 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6921 d 23 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6934 d 3 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6934 d 20 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	6954 d 20 h	jermar	/SPARTAN/trunk/	Move src/ and include/ to generic.
391	6982 d 20 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.
