842 6665 d 23 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
824 6673 d 3 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
822 6673 d 14 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
816 6673 d 23 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
814 6674 d 0 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
786 6676 d 20 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 6677 d 15 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
773 6678 d 11 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 6678 d 12 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
768 6679 d 13 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6679 d 14 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6679 d 15 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6679 d 20 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
762 6679 d 23 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6680 d 11 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6681 d 13 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 6682 d 12 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 6687 d 15 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 6690 d 20 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
733 6690 d 21 h bondari /kernel/trunk/test/mm/falloc2/ frame allocator test #2  
724 6695 d 16 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
692 6704 d 19 h bondari /kernel/trunk/ Frame allocation test #2  
689 6704 d 20 h bondari /kernel/trunk/ Frame alloc test #1  
687 6704 d 20 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
548 6737 d 17 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6739 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6739 d 17 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6751 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6752 d 14 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 6797 d 3 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6797 d 3 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6797 d 13 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 6798 d 3 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.		  
396 6799 d 0 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.)
