Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727
6746 d 9 h
jermar
/kernel/trunk/
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
704
6752 d 15 h
jermar
/kernel/trunk/
Make various mips32 tlb manipulation functions preserve EntryHi register.
Cleanup and more precise comments for previous commit.

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().

Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.

/kernel/trunk/arch/mips32/src/mm/
Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.

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.

/kernel/trunk/arch/mips32/
Fixes for mips32 invalidation functions.
598
6785 d 17 h
jermar
/kernel/trunk/arch/mips32/src/mm/
TLB invalidation functions for mips32. Not deployed yet. Not tested.
594

ptlb command (currently usable on mips32 only).
569
6788 d 9 h
jermar
/kernel/trunk/
sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.

Rename HelenOS/SPARTAN to HelenOS/kernel again.

Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.

Rename HelenOS/SPARTAN to HelenOS/kernel.
492
6805 d 9 h
jermar
/SPARTAN/trunk/
Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
413

jermar
/SPARTAN/trunk/
Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
403
6847 d 11 h
jermar
/SPARTAN/trunk/arch/
Small improvement in pte_t type definition.

/SPARTAN/trunk/
mips32 memory management work.
TLB exceptions seem to be working on at least simics.
msim handles TLB Refill and TLB Invalid exceptions well,
but seems to skip writes to the mapped addressies in mm
mapping test #1 (the data is not written and exception
is not triggered).
397
6850 d 22 h
jermar
/SPARTAN/trunk/
Small changes to mips32 mm.
Small changes in mm mapping test #1.
396
6851 d 19 h
jermar
/SPARTAN/trunk/
Add mm/mapping1 test.
(Will not make it past TLB Invalid exception on mips32.)
Fixes in asid.c.
Make TLB register types union with __u32 value.
Implement tlb_invalidate() for mips32.
(TLB invalidation and shootdown path will have to be revised.)
