1229 6629 d 0 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1227 6629 d 21 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.		  
1224 6629 d 23 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1221 6630 d 14 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6637 d 0 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1179 6640 d 20 h jermar /kernel/trunk/generic/src/mm/ Add some sanity checks to make sure the address space created by SYS_MAM_PHYSMEM will not be remapped
and that as_page_fault() will not try to service page fault for that area.		  
1178 6640 d 21 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1150 6649 d 4 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 6649 d 15 h jermar /kernel/trunk/generic/src/ s/B+-tree/B+tree/  
1147 6649 d 15 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 6651 d 19 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 6661 d 15 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1104 6661 d 20 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 6664 d 15 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 6667 d 0 h jermar /kernel/trunk/generic/src/mm/ Unlock address space area when returning error.  
1070 6667 d 3 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1063 6667 d 13 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1048 6667 d 22 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 6668 d 0 h jermar /kernel/trunk/ Page table locking.  
1037 6668 d 2 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1026 6668 d 13 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1008 6669 d 1 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 6669 d 12 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
983 6669 d 22 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6669 d 23 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6669 d 23 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6670 d 1 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
946 6671 d 15 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
852 6693 d 23 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 6697 d 0 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
826 6702 d 15 h jermar /kernel/trunk/ Add page_mapping_remove().  
824 6703 d 4 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
823 6703 d 14 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
822 6703 d 14 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 6703 d 15 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 6704 d 0 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
814 6704 d 1 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
813 6704 d 13 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 6705 d 22 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 6705 d 23 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
