[PATCH] drm/i915: Get audio power domain during initial hw readout

[PATCH] drm/i915: Get audio power domain during initial hw readout

[Bob Paauwe]

if the crtc has audio is enabled. Otherwise, when the first atomic
modeset happens it will warn when trying to drop the audio power
domain.

Hmm. Ideally we would do this alongside the other power doamin stuff in
intel_modeset_setup_hw_state(), but that's too late for
intel_sanitize_{crtc,encoder}(). So I guess we'll have to do it before
those, or we have to pull the audio power domain stuff out from the
encoder hooks. Or perhaps even throw it out entirely, since I'm not sure
it's doing anything for us.

If we do leave the power domain handling in the encoder hooks, then
this is not quite the right place to grab the reference. We could have
an encoder enabled w/o an active pipe, in which case
intel_sanitize_encoder() would shut off the encoder, so we'd still end
up with a bad refcount.

Thanks Ville for the details.  I'm not at all familiar with how this is
supposed to work so this helps some.  But I'm still not sure I follow.

If I move this to get_crtc_power_domains() by sticking 

   if (crtc_state->has_audio)
	mask |= BIT(POWER_DOMAIN_AUDIO);

at the end, which is where I think you're suggesting initially, it
seems to work.  So I'm not sure why that's too late.  Also, I'm not
seeing where shutting off the encoder will effect the power domain
refcounts.

Some of the encoder hooks will do the POWER_DOMAIN_AUDIO put/get, so if
sanitize_{crtc,encoder}() call just the disable hooks, we'll drop one to
many power references.

That said, I'm still not sure why we do the audio power domain frobbing
in the encoder code. That is, how can we end up enabling/disabling a port
with has_audio==true without the relevant power wells being on already.

Looks like some of this stuff was added in
commit d45a0bf549cd ("drm/i915: grab the audio power domain when enabling audio on HSW+")
so maybe Paulo knows?

I tried removing audio power domain frobbing from the encoder code (for
DP) and it didn't cause any problems on BXT. But I haven't been able to
run the pm_rpm tests on my BXT yet to verify that it doesn't cause any
regressions that way.

In any case, I sent a v2 that should have it setting the mask in the
correct place to at least resolve the warning messages I'm seeing.
