Subject: [PATCH 0/3] drm/i915: atomic_cdclk_freq fixes
Date: Mon, 14 Nov 2016 18:35:08 +0200 [thread overview]
Message-ID: <1479141311-11904-1-git-send-email-ville.syrjala@linux.intel.com> (raw)
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
My little fix for populating intel_state->cdclk with
dev_priv->atomic_cdclk_freq became a little meatier after I realized
that we really need to protect it with what is essentially a crtc
rwlock. That is, writers need to hold all the crtc locks, whereas
readers need to hold at least one.

drm/i915: Fix cdclk vs. dev_cdclk mess when not recomputing things
drm/i915: Protect dev_priv->atomic_cdclk_freq with all the crtc locks
drm/i915: Simplify error handling in intel_modeset_all_pipes()
