[Intel-gfx] [PATCH i-g-t 4/5] igt_dummyload: Add preemptible parameter to recursive batch

Antonio Argenziano antonio.argenziano at intel.com
Thu Dec 7 22:48:22 UTC 2017


This patch adds a parameter that allows to make the spinning batch
pre-emptible by conditionally adding an arbitration point to the spinning loop.

>From RFC:
	-	Implicitly initialize struct members to zero. (Chris)
