A bit more care required here since there are some very few things between the call to encoder->mode_set and encoder->pre_enable. But they're either book-keeping or only matter for the vga port on the pch. So of no concern. Note that with the new sequence we write the infoframes after selecting the clock source, but that shouldn't matter. I've simply opted for this to have simpler code. Reviewed-by:

All the hard work was already done, only thing left to do is remove the empty callback. And a now rather misleading comment I've spotted while reading through code. Reviewed-by:

Similar to dp the only thing we do is call intel_write_eld and prepare a bit of state for the enable hooks. The only difference is that we write that to the hardware instead of keeping track of it somewhere in software. Still we can just move all this to the very first enable hook. Reviewed-by:

Those functions are only used on vlv platforms, so no need to check. Especially if we're not too consistent about it. Reviewed-by:

With all the preceding refactoring the dp mode_set callback only computes a bit of state (all derived from the pipe config) and also writes the eld. As long as we do that before we enable the audio bit or depend upon the correct value in intel_dp->DP we'll be fine. No other hw state is touched. We therefore only need to check that clearing intel_dp->DP is save. Which it is since when we re-enable we already mask out all the bits the link training code sets. And we need to keep on doing that so that the re-train loop walking over pre-emph/voltage-swing values still works properly. Reviewed-by:

Only ilk/snb/ivb need the port A pll setup, so move it to the pre_enable hook for those platforms. We can savely do this since on those platforms there's nothing that touches the hardware between the encoder->mode_set and the encoder->pre_enable calls. Also add a comment that port A is ilk+ only.

Including state readout and cross-checking. This allows us to get rid of crtc->eld_vld on hsw+. It also means that fastboot will be unhappy if the BIOS hasn't set up the audio routing like we want it too. Wrt fastboot and external screens I see a few options: - Don't. - Try to fix up eld, infoframes and audio settings after the fact. But that means some pretty extensive reworking of our code which currently does all this while the pipe/port is still off. I won't bother with converting SDVO over to this because the audio support for SDVO is very lacking: - We don't update the eld. - We don't update the audio state on the sdvo encoder. - We don't check whether the platform can even feed audio to the sdvo encoder. I've converted hdmi, dp & ddi all in one go since ddi needs both hdmi and dp converted and so doing it step-by-step would have required a few intermediate hacks. Reviewed-by:

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:

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.

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).
