* wayland: Add support for eglSwapIntervalNeil Roberts2013-12-073-40/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Wayland EGL platform now respects the eglSwapInterval value. The value is clamped to either 0 or 1 because it is difficult (and probably not useful) to sync to more than 1 redraw. The main change is that if the swap interval is 0 then Mesa won't install a frame callback so that eglSwapBuffers can be executed as often as necessary. Instead it will do a sync request after the swap buffers. It will block for sync complete event in get_back_bo instead of the frame callback. The compositor is likely to send a release event while processing the new buffer attach and this makes sure we will receive that before deciding whether to allocate a new buffer. If there are no buffers available then instead of returning with an error, get_back_bo will now poll the compositor by repeatedly sending sync requests every 10ms. This is a last resort and in theory this shouldn't happen because there should be no reason for the compositor to hold on to more than three buffers. That means whenever we attach the fourth buffer we should always get an immediate release event which should come in with the notification for the first sync request that we are throttled to. When the compositor is directly scanning out from the application's buffer it may end up holding on to three buffers. These are the one that is is currently scanning out from, one that has been given to DRM as the next buffer to flip to, and one that has been attached and will be given to DRM as soon as the previous flip completes. When we attach a fourth buffer to the compositor it should replace that third buffer so we should get a release event immediately after that. This patch therefore also changes the number of buffer slots to 4 so that we can accomodate that situation. If DRM eventually gets a way to cancel a pending page flip then the compositors can be changed to only need to hold on to two buffers and this value can be put back to 3. This also moves the vblank configuration defines from platform_x11.c to the common egl_dri2.h header so they can be shared by both platforms.
* wayland: Block for the frame callback in get_back_bo not dri2_swap_buffersNeil Roberts2013-12-071-14/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider a typical game-style main loop which might be like this: while (1) { draw_something(); eglSwapBuffers(); } In this case the game is relying on eglSwapBuffers to throttle to a sensible frame rate. Previously this game would end up using three buffers even though it should only need two. This is because Mesa decides whether to allocate a new buffer in get_back_bo which would be before it has tried to read any events from the compositor so it wouldn't have seen any buffer release events yet. This patch just moves the block for the frame callback to get_back_bo. Typically the compositor will send a release event immediately after one of the attaches so if we block for the frame callback here then we can be sure to have completed at least one roundtrip and received that release event after attaching the previous buffer before deciding whether to allocate a new one. dri2_swap_buffers always calls get_back_bo so even if the client doesn't render anything we will still be sure to block to the frame callback. The code to create the new frame callback has been moved to after this call so that we can be sure to have cleared the previous frame callback before requesting a new one.

* i965/Gen7: Include bitfield in the sampler key for CMS layoutChris Forbes2013-12-072-0/+18
| | | | | | | | | | | | | | | | | | | | We need to emit extra shader code in this case to sample the MCS surface first; we can't just blindly do this all the time since IVB will sometimes try to access the MCS surface even if disabled. V3: Use actual MSAA layout from the texture's mt, rather then computing what would have been used based on the format. This is simpler and less fragile - there's at least one case where we might want to have a texture's MSAA layout change based on what the app does (CMS SINT falling back to UMS if the app ever attempts to render to it with a channel disabled.) This also obsoletes V2's 1/10 -- compute_msaa_layout can now remain an implementation detail of the miptree code.
