1150 6633 d 11 h jermar /kernel/trunk/generic/ Rename btree_node_left_sibling() to btree_leaf_node_left_neighbour()
and btree_node_right_sibling() to btree_leaf_node_right_neighbour()
as the left and right neighbours of a node needn't be its siblings.		  
1148 6633 d 21 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6633 d 21 h jermar /kernel/trunk/generic/ Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows.		  
1144 6636 d 1 h jermar /kernel/trunk/ Completed B+-tree support.
Enable btree_remove().
Reorder some static functions and group them together.
Fix order of nodes in the leaf_head list.		  
1108 6645 d 21 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1104 6646 d 2 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.		  
1093 6648 d 22 h palkovsky /kernel/trunk/generic/src/mm/ Fix bug with refcounts in frame allocator after zone_merge. (it caused some
frames not to be coalesced).		  
1076 6651 d 6 h jermar /kernel/trunk/generic/src/mm/ Unlock address space area when returning error.  
1070 6651 d 10 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1063 6651 d 20 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1048 6652 d 5 h jermar /kernel/trunk/generic/ Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.		  
1044 6652 d 7 h jermar /kernel/trunk/ Page table locking.  
1037 6652 d 8 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1026 6652 d 20 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1008 6653 d 7 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.		  
1002 6653 d 19 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
983 6654 d 4 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6654 d 5 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6654 d 6 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6654 d 8 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
946 6655 d 21 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
852 6678 d 5 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)		  
840 6681 d 6 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
826 6686 d 22 h jermar /kernel/trunk/ Add page_mapping_remove().  
824 6687 d 10 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
823 6687 d 20 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
822 6687 d 21 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 6687 d 21 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.		  
815 6688 d 7 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
814 6688 d 7 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
813 6688 d 20 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.		  
793 6690 d 5 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.		  
792 6690 d 5 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
791 6690 d 18 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab		  
789 6690 d 22 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 6691 d 2 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6691 d 3 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6691 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		  
785 6691 d 5 h jermar /kernel/trunk/generic/src/ Comments clarification.  
783 6691 d 6 h palkovsky /kernel/trunk/generic/ Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/
