1044 6820 d 9 h jermar /kernel/trunk/ Page table locking.  
983 6822 d 6 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
958 6823 d 2 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
831 6854 d 6 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).		  
830 6854 d 8 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().		  
765 6862 d 0 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6862 d 5 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
756 6863 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 6864 d 21 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.		  
730 6874 d 4 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6875 d 23 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
704 6882 d 5 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6882 d 9 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().		  
687 6887 d 5 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
618 6912 d 23 h jermar /kernel/trunk/arch/mips32/src/mm/ Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.  
612 6914 d 2 h jermar /kernel/trunk/arch/mips32/src/mm/ Weaken the assumption, that PageMask register contains the right mask everytime.
As a result, TLB exceptions will explicitly write this register when filling TLB entry.
Adjust tlb_print() on mips32 to print PageMask as well.		  
599 6915 d 7 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
598 6915 d 8 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
594 6916 d 2 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
569 6917 d 23 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
