6595 d 19 h
jermar
/kernel/trunk/generic/
Make address space backend data a union.
1424
6595 d 22 h
jermar
/kernel/trunk/
Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.
1423
6596 d 2 h
jermar
/kernel/trunk/
Update page fault handlers to distinguish between different access modes that had caused the page fault.
1417
6597 d 18 h
jermar
/kernel/trunk/generic/
Modify as_area_share() to accept destination area flags bitmask from the sender
(i.e. the sender can limit access mode to the shared area for the recipient).
Modify IPC_M_AS_AREA_SEND code to support this. Arguments for sender: arg1=as_area,
arg2=size, arg3=flags_mask.
The mechanism seems to work, but the page fault handlers need to be altered to
distinguish between faults under different access modes.
1416
6598 d 5 h
jermar
/kernel/trunk/generic/
Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change.
1415
6598 d 6 h
jermar
/kernel/trunk/generic/
Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount
1413
6598 d 17 h
jermar
/kernel/trunk/generic/
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
1411
6598 d 22 h
jermar
/kernel/trunk/
Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.
1409
6599 d 16 h
jermar
/kernel/trunk/generic/
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
1387
6602 d 0 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.
1382
6602 d 18 h
decky
/kernel/trunk/
make hardware memory mapping more generic
1380
6602 d 20 h
jermar
/kernel/trunk/
Turn address space lock, address space area lock and
page_ht_lock into mutexes.
1375
6604 d 4 h
jermar
/kernel/trunk/generic/
Fix race in condition variables.
1364
6606 d 1 h
jermar
/kernel/trunk/generic/
Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.
1359
6606 d 22 h
jermar
/kernel/trunk/generic/
Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.
1358
6606 d 22 h
jermar
/kernel/trunk/generic/
Cleanup after removal of as_area_accept and as_area_send.
1342
6607 d 6 h
jermar
/kernel/trunk/generic/
Improve comments.
1329
6608 d 22 h
palkovsky
/kernel/trunk/generic/
Added support to IPC for simple page sharing.
1327
6609 d 1 h
decky
/kernel/trunk/
split framebuffer initialization and sysinfo registration
1321
6609 d 6 h
vana
/kernel/trunk/generic/
force return 0 if no valid pointer in sysinfo syscall
