1108 6635 d 13 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
977 6643 d 21 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
902 6656 d 23 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.		  
895 6658 d 15 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.		  
894 6658 d 18 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
867 6663 d 21 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
838 6672 d 1 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6672 d 1 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
832 6675 d 13 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
811 6678 d 15 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.		  
810 6678 d 20 h cejka /kernel/trunk/genarch/ Added softint for emulation 32 and 64 bit division.
Not tested yet.		  
793 6679 d 20 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 21 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
760 6683 d 23 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.		  
756 6685 d 12 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 6686 d 11 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 21 h jermar /kernel/trunk/ Page hash table modifications.  
730 6695 d 18 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
699 6706 d 22 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
684 6708 d 21 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.
