/kernel/trunk/
Add some @file doxygen comments and improve already existing comments.
1239
6688 d 16 h
jermar
/kernel/trunk/generic/
Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.

6688 d 17 h
jermar
/kernel/trunk/generic/
Rename SYS_AS_AREA_SHARE_APPROVE and SYS_AS_AREA_SHARE_PERFORM, resp., to
SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND, resp. in syscall_t.
Fix prototype of as_area_send() to take only base address of the address
space area as a parameter and read size and flags from the address space
area found at this base address.
1236

jermar
/kernel/trunk/generic/
Add frame_reference_add().
1235
6688 d 22 h

/kernel/trunk/generic/
Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.
1233

/kernel/trunk/
Remove the outdated TODO file.
Improve doxygen comments here and there.
1227
6691 d 18 h

Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
1179
6702 d 17 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
6702 d 17 h
jermar
/kernel/trunk/
Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.

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.

s/B+-tree/B+tree/
1147
6711 d 12 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
6713 d 16 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.

Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.
1093
6726 d 12 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).

jermar
/kernel/trunk/generic/src/mm/
Unlock address space area when returning error.
1070

/kernel/trunk/
More checks for address space area conflicts.
1063

1048
6729 d 19 h
jermar
/kernel/trunk/generic/
Restore interrupts when failing in as_remap().
