From 423177140e9fcbd2ee5fef3845d4623f4ec31ed8 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 23 Jan 2020 14:57:55 +0000 Subject: [PATCH] drm/i915/selftests: Show the RC6 residency on parking failure Include the current RC6 residency counter in the error message, so that if we fail to park and manually enter RC6 we can see if the counter has a particularly suspect value (such as 0).
