2006-09-15Allow a "native type" to be associated with a fence sequence.Thomas Hellstrom
In the intel case, we can associate a flush with a sequence.
2006-09-15Some bugfixes.Thomas Hellstrom
Change the fence object interface somewhat to allow some more flexibility. Make list IOCTLS really restartable. Try to avoid busy-waits in the kernel using immediate return to user-space with an -EAGAIN.

2006-08-21i915 fence object driver implementing 2 fence object types:Thomas Hellstrom
0x00 EXE fence. Signals when command stream interpreter has reached the point where the fence was emitted. 0x01 FLUSH fence. Signals when command stream interpreter has reached the point where the fence was emitted, and all previous drawing operations have been completed and flushed. Implements busy wait (for fastest response time / high CPU) and lazy wait (User interrupt or timer driven).
