1221 6654 d 22 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6661 d 7 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1104 6686 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 6691 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 6695 d 10 h vana /kernel/trunk/ Better purge page selection.  
944 6696 d 0 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
928 6696 d 7 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
842 6720 d 7 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
824 6727 d 11 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
822 6727 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 6728 d 6 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
814 6728 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 6731 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 6731 d 23 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
773 6732 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 6732 d 20 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
768 6733 d 21 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6733 d 22 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6733 d 23 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6734 d 4 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
762 6734 d 7 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6734 d 19 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6735 d 20 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 6736 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 6741 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 6745 d 4 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
733 6745 d 5 h bondari /kernel/trunk/test/mm/falloc2/ frame allocator test #2  
724 6750 d 0 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
692 6759 d 3 h bondari /kernel/trunk/ Frame allocation test #2  
689 6759 d 4 h bondari /kernel/trunk/ Frame alloc test #1  
687 6759 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 6792 d 1 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6794 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6794 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6806 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6806 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 6851 d 11 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6851 d 11 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6851 d 21 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 6852 d 11 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
