[Mesa-dev] [PATCH 2/2] st/clover: Always flush the queue when waiting on an hard_event

[Niels Ole Salscheider]

The OpenCL spec says:
"Any blocking commands queued in a command-queue and clReleaseCommandQueue
perform an implicit flush of the command-queue. These blocking commands are
[...] or clWaitForEvents."

Flushing the queue unconditionally also helps to actually clear the
queued_events list of the queue object.
