793	6705 d 5 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	6705 d 6 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
786	6706 d 4 h	bondari	/kernel/trunk/	frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes. IMPORTANT: Parameter order for frame_alloc() was changed
778	6707 d 1 h	palkovsky	/kernel/trunk/	Fixed boot process not to call malloc when slab not initialized. Added simics workaround.
769	6708 d 18 h	palkovsky	/kernel/trunk/	SLAB allocator now uses itself for all its internal structures. Added description of allocator. Removed messy_stack_trace from amd64, as it would scroll away important part of exception.
765	6708 d 23 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
764	6709 d 4 h	palkovsky	/kernel/trunk/	Tested basic non-cached slab allocation.
763	6709 d 5 h	jermar	/kernel/trunk/	Modify frame.h to use shifting instead of multiplication and division. Define FRAME_WIDTH for all architectures.
762	6709 d 6 h	palkovsky	/kernel/trunk/	Currently not-working SLAB allocator. - slightly changed interface to frame_alloc, allow zone preference
760	6709 d 7 h	jermar	/kernel/trunk/	mips32 is not supposed to allocate page table. This is done by the generic code now. Remove PTL0 pointer as it is not needed. Remove GET_PTL0_ADDRESS from kernel. Update sparc64 comments in barrier.h.
758	6709 d 21 h	jermar	/kernel/trunk/arch/	sparc64 bugfix. When disabling IMMU and DMMU the kernel has to perform synchronization operation (e.g flush %r or membar #Sync instruction). There is no guarantee that the address contained in %r is in DTLB and therefore the flush instruction can fault. Normally this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler. However, this handler lives in virtually mapped memory and an attempt to execute there while the MMUs are disabled would result in a nested trap leading to error state. Replacing flush %r instruction with membar #Sync, wich is sufficient in this case, fixes this problem.
757	6709 d 23 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	6710 d 20 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	6711 d 19 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.
753	6712 d 3 h	jermar	/kernel/trunk/	Convert ASID management of ia64 to ASID FIFO mechanism. 18-bit RIDs are supported.
751	6712 d 6 h	jermar	/kernel/trunk/arch/ia64/	Fix initialization of pta.base on ia64.
750	6713 d 0 h	jermar	/kernel/trunk/	ia32 SMP updates. Update info about supported version of Bochs (bump the counter to 2.2.6). Add Task Priority Register type and initialize this register to a known state.
749	6714 d 3 h	jermar	/kernel/trunk/arch/ia64/	ia64 virtual address translation subsystem update.
748	6715 d 4 h	jermar	/kernel/trunk/arch/ia64/	First HT_HASH_ARCH implementation for ia64.
747	6715 d 21 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.
