This commit implements the atomic commit interfaces, and implements the legacy modeset and page flipping interfaces on top of them. There's two major changes in behavior from before: - We're now making use of interlocks between core and satellite EVO channels, which greatly improves our ability to keep their states synchronised. - DPMS is now implemented as a full modeset to either tear down the entire pipe (or bring it back up). This choice was made mostly to ease the initial implementation, but I'm also not sure what we gain by bring backing the old behaviour. We shall see. This does NOT currently expose the atomic ioctl by default, due to limited testing having been performed. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
