946 6664 d 17 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
940 6664 d 20 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
935 6664 d 22 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
880 6679 d 5 h jermar /kernel/trunk/generic/include/mm/ Fix conflict between asid_get() macro and function definitions.  
878 6680 d 1 h vana /kernel/trunk/ Active keyboard read for ia32  
869 6682 d 16 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
827 6695 d 16 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
826 6695 d 17 h jermar /kernel/trunk/ Add page_mapping_remove().  
823 6696 d 16 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
822 6696 d 16 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
820 6696 d 17 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.		  
816 6697 d 1 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
814 6697 d 3 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
793 6699 d 0 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
791 6699 d 14 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab		  
789 6699 d 18 h palkovsky /kernel/trunk/generic/ Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED.		  
788 6699 d 21 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6699 d 22 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6699 d 23 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		  
781 6700 d 14 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
778 6700 d 20 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
776 6701 d 0 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
771 6701 d 16 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
767 6702 d 17 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6702 d 18 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6702 d 23 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6703 d 0 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6703 d 1 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6703 d 14 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6704 d 15 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 6705 d 15 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.		  
754 6705 d 16 h jermar /kernel/trunk/generic/ Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.		  
735 6713 d 23 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
730 6714 d 22 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6716 d 17 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6718 d 19 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6720 d 18 h decky /kernel/trunk/ interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in		  
703 6723 d 2 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().		  
699 6726 d 2 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6727 d 23 h bondari /kernel/trunk/ Frame alloc test #1
