The kernel by default serializes the BCL on previous BCLs submitted on this FD, but not RCLs. For now this fix is conservative and blocks on last RCL if any vertex texturing is done, which fails to get bin/render overlap if there was an intermediate job that doesn't draw to the BCL's buffer. I've dropped a perf_debug() in here to note that as a potential future improvement. Fixes intermittent failures in KHR-GLES3.copy_tex_image_conversions.required.*

Support

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
