/kernel/trunk/generic/
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
1387
6652 d 14 h
jermar
/kernel/trunk/generic/
Add used_space_insert() and used_space_remove().
These are the alpha versions of functions that
will help to map used and unused portions of address
space areas. Currently unused, but many as_area operations
will be more efficient when the used space B+tree map
is used.

decky
/kernel/trunk/
make hardware memory mapping more generic
1380
6653 d 10 h
jermar
/kernel/trunk/
Turn address space lock, address space area lock and
page_ht_lock into mutexes.
1358
6657 d 13 h
jermar
/kernel/trunk/generic/
Cleanup after removal of as_area_accept and as_area_send.
1329
6659 d 12 h
palkovsky
/kernel/trunk/generic/
Added support to IPC for simple page sharing.
1306
6662 d 14 h
jermar
/kernel/trunk/generic/
Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.
1288
6668 d 18 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.
1239
6677 d 12 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.
1238
6677 d 13 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
6677 d 18 h
jermar
/kernel/trunk/generic/
Add frame_reference_add().
1235
6677 d 18 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
6679 d 17 h
jermar
/kernel/trunk/
Remove the outdated TODO file.
Improve doxygen comments here and there.
1227
6680 d 14 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
6691 d 13 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
6700 d 7 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
6704 d 11 h
jermar
/kernel/trunk/generic/include/
Fix comments.
1138
6707 d 13 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
6712 d 12 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.
