On as_area_destroy(), mark the area as partial before unlocking and free its
structure after unlocking.

jermar
/kernel/trunk/generic/
Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.

6719 d 1 h
jermar
/kernel/trunk/
Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.

Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.

6727 d 20 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
6728 d 1 h
jermar
/kernel/trunk/generic/
Add frame_reference_add().
1235
6728 d 1 h
jermar
/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

Remove the outdated TODO file.
Improve doxygen comments here and there.

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.

Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
1179
6741 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
6741 d 20 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.
