From 75081c6bfb9998bd7cbf35a7ac0578c683fe55a8 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 31 Dec 2018 09:14:12 +0000 Subject: i915/gem_busy: Use a non-preemptible hanging batch Ensure that the hangcheck notices the hanging batch by using a non-preemptible spin batch, as some future versions of hangcheck may allow a preemptible GPU hog to survive.
