-Subject: compositor: Add support for GL_EXT_x11_sync_object
-
-If GL advertises this extension we'll use it to synchronize X with GL
-rendering instead of relying on the XSync() behavior with open source
-drivers.
-
-Some driver bugs were uncovered while working on this so if we have
-had to reboot the ring a few times, something is probably wrong and
-we're likely to just make things worse by continuing to try.  Let's
-err on the side of caution, disable ourselves and fallback to the
-XSync() path in the compositor.

-+/* Theory of operation:
-+ *
-+ * We use a ring of NUM_SYNCS fence objects. On each frame we advance
-+ * to the next fence in the ring. For each fence we do:
-+ *
-+ * 1. fence is XSyncTriggerFence()'d and glWaitSync()'d
-+ * 2. NUM_SYNCS / 2 frames later, fence should be triggered
-+ * 3. fence is XSyncResetFence()'d
-+ * 4. NUM_SYNCS / 2 frames later, fence should be reset
-+ * 5. go back to 1 and re-use fence
-+ *
-+ * glClientWaitSync() and XAlarms are used in steps 2 and 4,
-+ * respectively, to double-check the expectections.

-Subject: compositor: Fix GL_EXT_x11_sync_object race condition
-
-The compositor maintains a ring of shared fences with the X server in order to
-properly synchronize rendering between the X server and the compositor's GPU
-channel.  When all of the fences have been used, the compositor needs to reset
-one so that it can be reused.  It does this by first waiting on the CPU for the
-fence to become triggered, and then sending a request to the X server to reset
-the fence.
-
-If the compositor's GPU channel is busy processing other work (e.g. the desktop
-switcher animation), then the X server may process the reset request before the
-GPU has consumed the fence.  This causes the GPU channel to hang.
-
-Fix the problem by having the compositor's GPU channel trigger its own fence
-after waiting for the X server's fence.  Wait for that fence on the CPU before
-sending the reset request to the X server.  This ensures that the GPU has
-consumed the X11 fence before the server resets it.

-Subject: compositor: Handle fences in the frontend X connection
-
-Since mutter has two X connections and does damage handling on the
-frontend while fence triggering is done on the backend, we have a race
-between XDamageSubtract() and XSyncFenceTrigger() causing missed
-redraws in the GL_EXT_X11_sync_object path.
-
-If the fence trigger gets processed first by the server, any client
-drawing that happens between that and the damage subtract being
-processed and is completely contained in the last damage event box
-that mutter got, won't be included in the current frame nor will it
-cause a new damage event.
-
-A simple fix for this would be XSync()ing on the frontend connection
-after doing all the damage subtracts but that would add a round trip
-on every frame again which defeats the asynchronous design of X
-fences.
-
-Instead, if we move fence handling to the frontend we automatically
-get the right ordering between damage subtracts and fence triggers.
