This implements intel overlay support for kms via a device-specific ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on dri-devel). We've reached the conclusion that such an infrastructure only makes sense when multiple kms overlay implementations exists, which atm don't (and it doesn't look like this is gonna change). Open issues: - Runs in sync with the gpu, i.e. unnecessary waiting. I've decided to wait on this because the hw tends to hang when changing something in this area. I left some dummy functions as infrastructure. - polyphase filtering uses a static table. - uses uninterruptible sleeps. Unfortunately the alternatives may unnecessarily wedged the hw if/when we timeout too early (and userspace only overloaded the batch buffers with stuff worth a few secs of gpu time). Changes since v1: - fix off-by-one misconception on my side. This fixes fullscreen playback. Changes since v2: - add underrun detection as spec'ed for i965. - flush caches properly, fixing visual corruptions. Changes since v4: - fix up cache flushing of overlay memory regs. - killed require_pipe_a logic - it hangs the chip.
