1221 6602 d 5 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6608 d 15 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1104 6633 d 10 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 6639 d 5 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 6642 d 18 h vana /kernel/trunk/ Better purge page selection.  
944 6643 d 7 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
928 6643 d 15 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
842 6667 d 14 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
824 6674 d 18 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
822 6675 d 5 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 6675 d 14 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
814 6675 d 15 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
786 6678 d 12 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 6679 d 6 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
773 6680 d 2 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 6680 d 3 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
768 6681 d 4 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6681 d 5 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6681 d 6 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6681 d 12 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
762 6681 d 14 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6682 d 2 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6683 d 4 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 6684 d 3 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 6689 d 6 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 6692 d 11 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
733 6692 d 13 h bondari /kernel/trunk/test/mm/falloc2/ frame allocator test #2  
724 6697 d 7 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
692 6706 d 10 h bondari /kernel/trunk/ Frame allocation test #2  
689 6706 d 11 h bondari /kernel/trunk/ Frame alloc test #1  
687 6706 d 11 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
548 6739 d 8 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6741 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6741 d 8 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6753 d 13 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6754 d 6 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 6798 d 18 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6798 d 18 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.		  
399 6799 d 4 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 6799 d 18 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
