Rev	Age	Author	Path	Log message
2089	6323 d 9 h	decky	/trunk/	huge type system cleanup remove cyclical type dependencies across multiple header files many minor coding style fixes
2071	6334 d 2 h	jermar	/trunk/	(c) versus (C)
1851	6483 d 9 h	jermar	/trunk/kernel/	sparc64 work. Define the istate structure. Move the identity-mapping handler to assembly. Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it. Little bit of formatting and indentation.
1787	6524 d 4 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1780	6531 d 5 h	jermar	/kernel/trunk/	Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
1702	6552 d 8 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
1424	6569 d 4 h	jermar	/kernel/trunk/	Move the sharing functionality to address space area backends. Add backend for continuous regions of physical memory. Sharing for these areas works automagically now.
1380	6576 d 3 h	jermar	/kernel/trunk/	Turn address space lock, address space area lock and page_ht_lock into mutexes.
1266	6595 d 9 h	jermar	/kernel/trunk/genarch/	Rename acpi/matd.c to madt.c (Multiple APIC Description Table). Improve Doxygen comments in genarch/.
1248	6599 d 5 h	jermar	/kernel/trunk/	Add some @file doxygen comments and improve already existing comments.
1229	6602 d 9 h	jermar	/kernel/trunk/	Remove the outdated TODO file. Improve doxygen comments here and there.
1044	6641 d 9 h	jermar	/kernel/trunk/	Page table locking.
922	6648 d 0 h	jermar	/kernel/trunk/genarch/src/mm/	Fix generic page hash table to align down page addresses. This was the ia64 userspace show stopper.
902	6656 d 9 h	jermar	/kernel/trunk/	ia64 work. More capable TLB miss handlers. The ia64 kernel now passes mm/mapping1 test. Fix generic hash table to properly initialize lists. Change page_ht() to properly initialize inserted PTE's. Change format of generic page hash table PTE's.
826	6676 d 0 h	jermar	/kernel/trunk/	Add page_mapping_remove().
823	6676 d 23 h	jermar	/kernel/trunk/	Reimplement ASID stealing logic. This time, hopefully, with correct synchronization.
815	6677 d 9 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
793	6679 d 7 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.
792	6679 d 8 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
757	6684 d 1 h	jermar	/kernel/trunk/	Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator. This area contains VGA text frame buffer and should be avoided. falloc2 test now passes on ia64.
756	6684 d 22 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	6685 d 22 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.
746	6690 d 8 h	jermar	/kernel/trunk/	Page hash table modifications.
699	6706 d 9 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
687	6708 d 6 h	jermar	/kernel/trunk/	Memory management work. Pass address space identifier to functions in page_operations to support single global page hash table.
684	6708 d 7 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.
