Hi Dave,
Here's the pull request for HDCP. Hopefully no surprises since it's been baking
in drm-tip for a while now.

topic/hdcp-2018-02-13:
Add HDCP support to i915 drm driver.

Cheers, Sean

Were these ever posted to dri-devel? I can't find them there.

Do these patches from Ramalingam C add repeater support to the i915?
If so, then I am certainly interested in seeing these since we (Cisco)
are working on HDCP (including repeater support) for HDMI receivers.

Nothing public yet, it's too early for that. But it would be nice to
test with the i915 driver.

Regards,

	Hans

Hi Hans!
We had a conversation on these patches and repeater support when I
initially posted them :-)
https://lists.freedesktop.org/archives/intel-gfx/2017-December/149112.html

It'd be great if you could try it out and report back.

Cheers,

Sean

Yes, your patches I've seen, but the 12 from Ramalingam I haven't seen.
At least not on dri-devel. It's a bit weird.

Ahh, I'm sorry I misunderstood. I think Ram may have sent those to intel-gfx
exclusively.

Repeater support was introduced in the initial post. Ram's changes mainly focus
on HDCP compliance.

We rarely post i915 specific patches to dri-devel, just intel-gfx, but
in cases where they warrant changes in drm core it may be warranted to
add a wider audience. Sorry about failing to do that here.

All the commits have Link: tags back to the patches posted publicly,
with message-ids.


BR,
Jani.
