From 08ea70a417baa1c0e5faa580070cd2ffd04e6285 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Sun, 12 Aug 2018 23:36:31 +0100 Subject: [PATCH] drm/i915: Disable runtime-pm using lowlevel functions if !HAS_RC6 If we cannot setup rc6, we cannot let the GPU suspend itself as it cannot save its state (to a powercontext). As such, we must disable runtime-pm, but we should do so using the low-level pm-runtime function which leaves our own debugging functions intact (and continue to detect errors in our runtime-pm handling should we ever be able to enable rc6).
