1760 6537 d 4 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1666 6552 d 7 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.		  
1658 6552 d 12 h vana /kernel/trunk/test/ Detaching threads in tests  
1221 6598 d 22 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6605 d 7 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1104 6630 d 3 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1062 6635 d 22 h jermar /kernel/trunk/ It is now possible to associate symbolic names with both threads and tasks.
More verbose kconsole threads, tasks and scheduler commands.		  
947 6639 d 10 h vana /kernel/trunk/ Better purge page selection.  
944 6640 d 0 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
928 6640 d 7 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
842 6664 d 7 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
824 6671 d 11 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
822 6671 d 22 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 6672 d 7 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
814 6672 d 8 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
786 6675 d 4 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 6675 d 23 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
773 6676 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 6676 d 20 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
768 6677 d 21 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6677 d 22 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6677 d 23 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6678 d 4 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
762 6678 d 7 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6678 d 19 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6679 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 6680 d 20 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 6685 d 23 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 6689 d 4 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
733 6689 d 5 h bondari /kernel/trunk/test/mm/falloc2/ frame allocator test #2  
724 6694 d 0 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
692 6703 d 3 h bondari /kernel/trunk/ Frame allocation test #2  
689 6703 d 4 h bondari /kernel/trunk/ Frame alloc test #1  
687 6703 d 4 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
548 6736 d 1 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6738 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6738 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6750 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6750 d 22 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 6795 d 11 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.
