[Intel-gfx] [PATCH 0/2] Disable connector polling for a headless sku

[Jouni Högander]

This patch set disables connector polling when entering runtime
suspend for headless sku to prevent waking it up again when poll
is performed.

[Intel-gfx] [PATCH 1/2] drm/i915/opregion: add function to check if headless sku

[Jouni Högander]

Export headless sku bit (bit 13) from opregion->header->pcon as an
interface to check if our device is headless configuration.

Here we go again.

What does headless mean here? The spec does not say. Does it have
display hardware? Apparently yes, since otherwise we wouldn't be here.

We have INTEL_DISPLAY_ENABLED() which should do the right thing when you
do have display hardware and have done output setup etc. but want to
force them disconnected, i.e. you take the hardware over properly, but
put it to sleep for power savings.

Maybe we should bolt this opregion check in that macro?

Maybe we need to use INTEL_DISPLAY_ENABLED() also to prevent polling.

I certainly would not want to add another mode that's separate from
HAS_DISPLAY() and INTEL_DISPLAY_ENABLED().

We should probably start checking for opregion version for this stuff
too.

This is for hybrid setup with several display hw and the panel wont be
connected into device driven by i915 driver.

Thank you for pointing this out. HAS_DISPLAY I already notice and it's
not suitable for what we want here. I think bolting this check into
INTEL_DISPLAY_ENABLED as you suggested is enough. That will prevent
waking up the hw into D0 state for polling.

No need for this. I think we can go with INTEL_DISPLAY_ENABLED.

A headless sku should not have any DDI ports enabled, much easier check for that.

Could you please clarify this a bit? What exactly you are thinking
should be checked? Aren't DDI port also disabled when non-headless
setup is in runtime suspend?

I also think "headless" and "DDI ports enabled" need clarification. They
are overloaded terms.

Seems to me the use case here could be the same as
INTEL_DISPLAY_ENABLED(), and that could benefit from polling disable.

In a properly setup headless sku, VBT should have all ports marked as disabled.

intel_ddi_init() {
	...

	if (!init_dp && !init_hdmi) {
		drm_dbg_kms(&dev_priv->drm,
			    "VBT says port %c is not DVI/HDMI/DP compatible, respect it\n",
			    port_name(port));
		return;
	}


All DDI should return earlier in the above.
So you can use the number of enabled connectors to know if it is a headless sku or not.

So you can skip the pooling in case there is no connectors.

This is what I mean with overloaded terms. Now we're at "properly setup
headless sku", and we're none the wiser. ;)

Is the hardware there?

If not, okay, but why aren't the pipes fused then? Why a different flag
in opregion?

If yes, has the GOP taken over the hardware and put it into power save?

Should we take into account headless bit in opregion possibly
conflicting with VBT contents?

Now as you pointed out this I started to think
intel_opregion_headless_sku check could be also in here as additional
check:

if (!init_dp && !init_hdmi || intel_opregion_headless_sku()) {

This would prevent initializing any connector including setting them up
for polling?

I went through this and to my understanding this polling doesn't happen
in setup where all ports are marked as disabled in VBT. Connector is
not initialized at all -> polling is not enabled when runtime suspend
happens.

[Intel-gfx] [PATCH 2/2] drm/i915: do not start connector polling when headless sku

[Jouni Högander]

Connector polling is waking up the polled device. Polling
is unnecessary if our device is known to not have display.

Fix this and Save some power by disabling starting connector
polling when we are having headless sku. Use information from
opregion.
