From 6484775766e37049883d49e7ee9c1a174f0d0524 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Sun, 7 Apr 2019 20:26:49 +0100 Subject: [PATCH] drm/i915/selftests: Mark live_forcewake_ops as unreliable A couple of machines in the farm show quite frequent errors in the powerwells not being released. Either there is an external agent interferring with the powerwells, or the powerwell doesn't quite behave as we anticipate -- either way, the test is not reliable enough to be enabled by default in CI. It has served its immediate purpose in providing coverage as we made tweaks to forcewake, so keep it available for future testing.
