Subject: [PATCH 69/81] drm/i915: push commit_output_state past the crtc/encoder preparing
Date: Wed, 11 Jul 2012 16:28:52 +0200 [thread overview]
Message-ID: <1342016944-23395-70-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1342016944-23395-1-git-send-email-daniel.vetter@ffwll.ch>
With this change we can (finally!) rip out a few of the temporary hacks
and clean up a few other things:
- Kill intel_crtc_prepare_encoders, now unused.
- Kill the hacks in the crtc_disable/enable functions to always call the
encoder callbacks, we now always call the crtc functions with the right
encoder -> crtc links.
- Also push down the crtc->enable, encoder and connector dpms state
updates. Unfortunately we can't add a WARN in the crtc_disable
callbacks to ensure that the crtc is always still enabled when
disabling an output pipe - the crtc sanitizer of the hw readout path
can hit this when it needs to disable an active pipe without any
enabled outputs.
- Only call crtc->disable if the pipe is already enabled - again avoids
running afoul of the new WARN.
v2: Copy&paste our own version of crtc_in_use, too.
v3: We need to update the dpms an encoder->connectors_active states,
too.
v4: I've forgotten to kill the unconditional encoder->disable calls in
the crtc_disable functions.
