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,
