2014-04-25drm/i915: Break encoder->crtc link separately in intel_sanitize_crtc()Egbert Eich
Depending on the SDVO output_flags SDVO may have multiple connectors linking to the same encoder (in intel_connector->encoder->base). Only one of those connectors should be active (ie link to the encoder thru drm_connector->encoder). If intel_connector_break_all_links() is called from intel_sanitize_crtc() we may break the crtc connection of an encoder thru an inactive connector in which case intel_connector_break_all_links() will not be called again for the active connector if this happens to come later in the list due to: if (connector->encoder->base.crtc != &crtc->base) continue; in intel_sanitize_crtc(). This will however leave the drm_connector->encoder linkage for this active connector in place. Subsequently this will cause multiple warnings in intel_connector_check_state() to trigger and the driver will eventually die in drm_encoder_crtc_ok() (because of crtc == NULL). To avoid this remove intel_connector_break_all_links() and move its code to its two calling functions: intel_sanitize_crtc() and intel_sanitize_encoder(). This allows to implement the link breaking more flexibly matching the surrounding code: ie. in intel_sanitize_crtc() we can break the crtc link separatly after the links to the encoders have been broken which avoids above problem. This regression has been introduced in: commit 24929352481f085c5f85d4d4cbc919ddf106d381 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Jul 2 20:28:59 2012 +0200 drm/i915: read out the modeset hw state at load and resume time so goes back to the very beginning of the modeset rework. v2: This patch takes care of the concernes voiced by Chris Wilson and Daniel Vetter that only breaking links if the drm_connector is linked to an encoder may miss some links. v3: move all encoder handling to encoder loop as suggested by Daniel Vetter.

2014-04-25drm/i915: Don't WARN nor handle unexpected hpd interrupts on gmch platformsDaniel Vetter
The status bits are unconditionally set, the control bits only enable the actual interrupt generation. Which means if we get some random other interrupts we'll bogusly complain about them. So restrict the WARN to platforms with a sane hotplug interrupt handling scheme. And even more important also don't attempt to process the hpd bit since we've detected a storm already.

2014-04-25drm/msm/mdp4: cure for the cursor blues (v2)Rob Clark
The hw cursor is relatively adept at triggering underflows, which manifest as a "blue flash" (since blue is configured as the underflow color). Juggle a few things around to tighten up the timing for setting cursor registers in DONE irq. And most importantly, don't ever disable the hw cursor. Instead flip it to a blank/empty cursor. This seems far more reliable, as even simply clearing the cursor-enable bit (with no other updates in previous/ following frames) can in some cases cause underflow. v1: original v2: add missing locking spotted by Micah Cc: Micah Richert <richert@braincorporation.com> Signed-off-by: Rob Clark <robdclark@gmail.com>

This is because the drm core will already set crtc->primary->fb to NULL and do the unref for us, and the crtc disable hook is called by the drm crtc helpers for exactly this case. Aside: Now that the fbdev helpers clean up planes there's no longer a need to do this in drivers. So this could probably be nuked entirely in linux-next.

2014-04-23drm/i915: get power domain in case the BIOS enabled eDP VDDPaulo Zanoni
If I unplug the eDP monitor, the BIOS of my machine will enable the VDD bit, then when the driver loads it will think VDD is enabled. It will detect that the eDP is not enabled and return false from intel_edp_init_connector. This will trigger a call to edp_panel_vdd_off_sync(), which trigger a WARN saying that the refcount of the power domain is less than zero. The problem happens because the driver gets a refcount whenever it enables the VDD bit, and puts the refcount whenever it disables the VDD bit. But on this case, the BIOS enabled VDD, so all we do is to call put() without calling get() first, so the code added is there to make sure we always have the get() in case the BIOS enabled the bit.

2014-04-23drm/i915: Don't check gmch state on inherited configsDaniel Vetter
... our current modeset code isn't good enough yet to handle this. The scenario is: 1. BIOS sets up a cloned config with lvds+external screen on the same pipe, e.g. pipe B. 2. We read out that state for pipe B and assign the gmch_pfit state to it. 3. The initial modeset switches the lvds to pipe A but due to lack of atomic modeset we don't recompute the config of pipe B. -> both pipes now claim (in the sw pipe config structure) to use the gmch_pfit, which just won't work.

2014-04-22drm/i915: Allow user modes to exceed DVI 165MHz limitVille Syrjälä
In commit commit 6375b768a9850b6154478993e5fb566fa4614a9c Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Mon Mar 3 11:33:36 2014 +0200 drm/i915: Reject >165MHz modes w/ DVI monitors the driver started to filter out display modes which exceed the single-link DVI 165Mz dotclock limits when the monitor doesn't report itself as being HDMI compliant. The intent was to filter out all EDID derived modes that require dual-link DVI to operate since we don't support dual-link. However the patch went a bit too far and also causes the driver to reject such modes even when specified by the user. Normally we don't check the sink limitations when setting a mode from the user. This allows the user to specify any mode whether the sink reports to support it or not. This can be useful since often the sinks support more modes than they report in the EDID. So relax the checks a bit, and apply the single-link DVI dotclock limit only when filtering the mode list, and ignore the limit when setting a user specified mode.
