755 6693 d 7 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 6702 d 14 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6704 d 9 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6706 d 11 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
704 6710 d 15 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6710 d 18 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().		  
689 6715 d 15 h bondari /kernel/trunk/ Frame alloc test #1  
687 6715 d 15 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
684 6715 d 16 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.		  
623 6739 d 21 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
618 6741 d 8 h jermar /kernel/trunk/arch/mips32/src/mm/ Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.  
612 6742 d 12 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 6743 d 17 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
598 6743 d 17 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
595 6744 d 11 h palkovsky /kernel/trunk/ Fixed bug in vm.c that turned off preemption. Found in versions 390:391.  
594 6744 d 12 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
573 6745 d 13 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
569 6746 d 9 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
548 6748 d 12 h jermar /kernel/trunk/ Cleanup and fixes.  
536 6750 d 10 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage
