869 6727 d 18 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
827 6740 d 19 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
826 6740 d 20 h jermar /kernel/trunk/ Add page_mapping_remove().  
823 6741 d 18 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
822 6741 d 19 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 6741 d 20 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 6742 d 4 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.
 
814 6742 d 5 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
793 6744 d 3 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 6744 d 16 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab
 
789 6744 d 20 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 6745 d 0 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6745 d 1 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.
 
786 6745 d 2 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 6745 d 17 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.
 
778 6745 d 23 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
776 6746 d 3 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.
 
771 6746 d 19 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
767 6747 d 19 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6747 d 20 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6748 d 2 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6748 d 3 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
 
762 6748 d 4 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
759 6748 d 16 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6749 d 18 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 6750 d 17 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 6750 d 18 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 6759 d 1 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
730 6760 d 0 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6761 d 20 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
724 6763 d 21 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6765 d 21 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 6768 d 5 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 6771 d 5 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.
 
689 6773 d 1 h bondari /kernel/trunk/ Frame alloc test #1  
687 6773 d 2 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
686 6773 d 3 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6773 d 3 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.
 
683 6773 d 3 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.
 
676 6776 d 23 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.
