1221 6638 d 0 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6644 d 10 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1104 6669 d 6 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 6675 d 1 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 6678 d 13 h vana /kernel/trunk/ Better purge page selection.  
944 6679 d 3 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
928 6679 d 10 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
842 6703 d 10 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
824 6710 d 14 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
822 6711 d 0 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 6711 d 9 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
814 6711 d 11 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
786 6714 d 7 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 6715 d 2 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
773 6715 d 21 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 6715 d 22 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
768 6716 d 23 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6717 d 1 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6717 d 1 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6717 d 7 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
762 6717 d 9 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6717 d 21 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6718 d 23 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 6719 d 23 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 6725 d 2 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 6728 d 6 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
733 6728 d 8 h bondari /kernel/trunk/test/mm/falloc2/ frame allocator test #2  
724 6733 d 2 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
692 6742 d 6 h bondari /kernel/trunk/ Frame allocation test #2  
689 6742 d 7 h bondari /kernel/trunk/ Frame alloc test #1  
687 6742 d 7 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
548 6775 d 4 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6777 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6777 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6789 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6790 d 1 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 6834 d 14 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6834 d 14 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6835 d 0 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 6835 d 13 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
