840 6652 d 17 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
830 6657 d 16 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().		  
823 6659 d 7 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
819 6659 d 10 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6659 d 13 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
816 6659 d 16 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
815 6659 d 17 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
813 6660 d 6 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.		  
811 6660 d 10 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.		  
793 6661 d 15 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 6661 d 16 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
786 6662 d 14 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		  
763 6665 d 15 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6665 d 16 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
758 6666 d 7 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 6666 d 10 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 6667 d 6 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.		  
753 6668 d 14 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
751 6668 d 16 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6670 d 14 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.
