-Subject: [PATCH] drm/vc4: Fix termination of the initial scan for branch
- targets.
-
-The loop is scanning until the original max_ip (size of the BO), but
-we want to not examine any code after the PROG_END's delay slots.
-There was a block trying to do that, except that we had some early
-continue statements if the signal wasn't a PROG_END or a BRANCH.
-
-The failure mode would be that a valid shader is rejected because some
-undefined memory after the PROG_END slots is parsed as a branch and
-the rest of its setup is illegal.  I haven't seen this in the wild,
-but valgrind was complaining when about this up in the userland
-simulator mode.

-Subject: [PATCH] drm/vc4: Use runtime autosuspend to avoid thrashing V3D power
- state.
-
-The pm_runtime_put() we were using immediately released power on the
-device, which meant that we were generally turning the device off and
-on once per frame.  In many profiles I've looked at, that added up to
-about 1% of CPU time, but this could get worse in the case of frequent
-rendering and readback (as may happen in X rendering).  By keeping the
-device on until we've been idle for a couple of frames, we drop the
-overhead of runtime PM down to sub-.1%.
