From d36388a9f2dfc76ac3ccc963242de1f44f9cacd4 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 2 Oct 2018 12:23:24 +0100 Subject: igt/kms_busy: Flush request queue when re-enabling hangcheck Enabling hangcheck only takes effect at the start of a new request queue. Before we re-enable hangcheck after our poking around, we therefore need to wait until the gpu is idle otherwise the next test will start without hangcheck and subsequently hang forever.
