786 6702 d 5 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		  
780 6703 d 0 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
773 6703 d 19 h palkovsky /kernel/trunk/ Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu.		  
772 6703 d 20 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
768 6704 d 21 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6704 d 23 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6704 d 23 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6705 d 5 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
762 6705 d 7 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6705 d 19 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6706 d 21 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 6707 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.		  
745 6713 d 0 h jermar /kernel/trunk/test/mm/ Fix and cleanup frame allocator tests.
falloc1:
- fix so that it compiles on ia64
- check that frames is not NULL
falloc2:
- threads cannot be passed argument in the way this test did
(otherwise some threads will use the same value for val)
- check that frames is not NULL
- free frames at the end of the test		  
735 6716 d 4 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
733 6716 d 6 h bondari /kernel/trunk/test/mm/falloc2/ frame allocator test #2  
724 6721 d 0 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
692 6730 d 4 h bondari /kernel/trunk/ Frame allocation test #2  
689 6730 d 5 h bondari /kernel/trunk/ Frame alloc test #1  
687 6730 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.		  
548 6763 d 2 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6765 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6765 d 2 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6777 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6777 d 23 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.		  
401 6822 d 12 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6822 d 12 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6822 d 22 h jermar /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 6823 d 11 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6824 d 9 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.)
