There's no need to check whether audio is enabled (which for ddi ports is done through the crtc->eld_vld flag) since at the cost of a potentially unecessary register rmw cycle we can unconditionally do this. Note that the edp check is just paranoia since we won't ever call the write_eld function for an edp panel. Reviewed-by:

This way we can rely on the state cross-checker to have a bit assurance that we'll get it right. Reviewed-by:

At least on those platforms which have a simple bit and don't rely on the fully programmable CSC unit to do this. Note that with the current code this includes CHV, but I guess that platform will match BYT. Reviewed-by:

We in the pre_enable hook we should only rely on the pipe config and not on some other state set through properties or detect functions. Reviewed-by:

Also add state readout and cross-check support. The only invasive change is wiring up the new flag to the ->set_infoframes callbacks. Reviewed-by:

For compliance we really should be sending NULL infoframes always when we detect a hdmi capable monitor. Also remove the now redudant setting for the has_audio case and enforce that audio is only possible with a hdmi sink. Reviewed-by:

Almost all of it is reusable from the existing code. The primary difference is we need to do even less in the interrupt handler, since interrupts are not shared in the same way. The patch is mostly a copy-paste of the existing snb+ code, with updates to the relevant parts requiring changes to the interrupt handling. As such it /should/ be relatively trivial. It's highly likely that I missed some places where I need a gen8 version of the PM interrupts, but it has become invisible to me by now. This patch could probably be split into adding the new functions, followed by actually handling the interrupts. Since the code is currently disabled (and broken) I think the patch stands better by itself. v2: Move the commit about not touching the ringbuffer interrupt to the snb_* function where it belongs (Rodrigo) v3: Rebased on Paulo's runtime PM changes v4: Not well validated, but rebase on commit 730488b2 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Fri Mar 7 20:12:32 2014 -0300 drm/i915: kill dev_priv->pm.regsave v5: Rebased on latest code base.

If we dont have semaphores enabled, we allocate 4 dwords for signalling. But end up emitting more regardless. Fix this by bailing out early if semaphores are not enabled.

Otherwise we end up tearing down fences when e.g. the client quits way too early. Might or might not fix a fence pin_count BUG Ville has reported. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Daniel Vetter authored
Userspace can currently provoke this when e.g. trying to use a pinned scanout as a cursor or overlay target. Later on that might lead to some fun fence pin count mayhem. Spurred by Ville's report that something goes wrong here and originally I've thought that this might slip through the pwrite gtt fastpath. But that one checks of obj tiling, so should be ok. But one thing that _does_ blow up is the vma unbinding with more than one address space. The next patch will fix this. v2: Use a WARN_ON - Chris pointed out that we already catch all cases so userspace can't provoke this like I've originally feared. While reviewing relevant code I've noticed a pile of DRM_ERROR in the overlay&cursor code which are all triggerable by userspace. Tune them down while at it. v3: Split out the DRM_ERROR->DRM_DEBUG_KMS change into a separate patch, as requested by Chris.

During initial probing of the modes to assign to the fbdev console, we use the CRTC and connector ids. These are much harder for us to understand than if we used their actual names (or pipe in the CRTC case). Similarly, we want to manually print the mode size rather than rely on mode->name being set.

The fence pin count should always be <= the bo pin count. If that's not the case then we have a funny problem and are leaking references somewhere. Which means we can catch fence pin leaks by checking for the same upper limit as we do for the bo pin count. Inspired by a discussion with Ville about a fence leak igt testcase. v2: Also check for fence->pin_count <= ggtt_vma->pin_count, since that might catch a leak even quicker. Also de-inline them, they're getting too big. v3: Don't separately check for MAX_PIN_COUNT since the > vma->pin_count check will catch that already (Chris).
