/kernel/trunk/generic/
Added support to IPC for simple page sharing.

jermar
/kernel/trunk/generic/
Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.
1288
6724 d 12 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.

/kernel/trunk/generic/
Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.
1238
6733 d 7 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
6733 d 12 h
jermar
/kernel/trunk/generic/
Add frame_reference_add().
1235
6733 d 13 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.
1229

jermar
/kernel/trunk/
Remove the outdated TODO file.
Improve doxygen comments here and there.
1227
6736 d 8 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.
1178
6747 d 8 h
jermar
/kernel/trunk/
Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.

/kernel/trunk/generic/include/mm/
s/B+-tree/B+tree/
1147
6756 d 2 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.
1139
6760 d 6 h
jermar
/kernel/trunk/generic/include/
Fix comments.
1138
6763 d 8 h
jermar
/kernel/trunk/
CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().
1104
6768 d 7 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.
1070
6773 d 14 h
jermar
/kernel/trunk/
More checks for address space area conflicts.
1063
6774 d 1 h
palkovsky
/kernel/trunk/
Add support for more then 2GB of address space for AMD64.
1048
6774 d 10 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
6774 d 11 h
jermar
/kernel/trunk/
