In commit commit e4ca061275ec6a48b66c6edebe08644e666994c0 Author: Patrik Jakobsson <patrik.jakobsson@linux.intel.com> Date: Wed Jul 8 15:31:52 2015 +0200 drm/i915: Don't forget to mark crtc as inactive after disable we added extra watermark updates to all of the .crtc_disable() entrypoints to avoid problems problems with system resume on SKL. Those disable entrypoints are currently called in just two places in the driver: intel_atomic_commit (i.e., during a modeset) and intel_crtc_disable_noatomic (which is called during hardware readout). It seems that this extra watermark recalculation should only be important in the latter case (which happens during a resume operation); the former case should always have appropriate watermark programming happening at other points in the modeset sequence. Let's move the watermark update out of the .crtc_disable() entrypoints and place it directly in intel_crtc_disable_noatomic() so that it only happens on S3 resume and not during a regular modeset (since the existing watermark handling should properly update watermarks during normal atomic commits).
