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. Instead just clear the bit silently.

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>

In Matt Ropers primary plane series a set of prep patches like commit af2b653bfb4ef40931b4d101ca842ce0c5da57ef Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Apr 1 15:22:32 2014 -0700 drm/i915: Restrict plane loops to only operate on overlay planes (v2) ensured that all exisiting users of the mode_config->plane_list wouldn't change behaviour. Unfortunately tegra seems to have fallen through the cracks. Fix it. This regression was introduced in commit e13161af80c185ecd8dc4641d0f5df58f9e3e0af Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Apr 1 15:22:38 2014 -0700 drm: Add drm_crtc_init_with_planes() (v2) The result was that we've unref'ed the fb for the primary plane twice, leading to a use-after free bug. 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.

While at it add a DOC: comment for the probing libraray. It would be rather neat to pull some of the DocBook documenting these two helpers into in-line DOC: comments.

2014-04-18drm/plane-helper: Don't fake-implement primary plane disablingDaniel Vetter
After thinking about this topic a bit more I've reached the conclusion that implementing this doesn't make sense: - The locking is all wrong: set_config(NULL) will also unlink encoders and connectors, but those links are protected with the mode_config mutex. In the ->disable_plane callback we only hold all modeset locks, but eventually we want to switch to just grabbing the per-crtc (and maybe per-plane) locks as needed, maybe based on ww_mutexes. Having a callback which absolutely needs all modeset locks is bad for this conversion. Note that the same isn't true for the provided ->update_plane since we've audited the crtc helpers to make sure that not encoder or connector links are changed. - There's no way to re-enable the plane with an ->update_plane: The connectors/encoder links are lost and so we can't re-enable the CRTC. Even without that issue the driver might have reassigned some shared resources (as opposed to e.g. DPMS off, where drivers are not allowed to do that to make sure the CRTC can be enabled again). - The semantics don't make much sense: Userspace asked to scan out black (or some other color if the driver supports a background color), not that the screen be disabled. - Implementing proper primary plane support (i.e. actually disabling the primary plane without disabling the CRTC) is really simple, at least if all the hw needs is flipping a bit. The big task is auditing all the interactions with other ioctls when the CRTC is on but there's no primary plane (e.g. pageflips). And some of that work still needs to be done.
