Qualcomm Looks To Add HDCP Support To Freedreno

One month ago was the surprising contribution by Qualcomm's Innovation Center that they were adding new hardware support to Freedrenon, the open-source and reverse-engineered Gallium3D driver for Adreno graphics hardware. Qualcomm's contributions haven't ended and they're looking to add more patches -- including for HDCP support.

Published this week was a nearly two thousand line patch for adding HDMI HDCP support. HDCP is the High-bandwidth Digital Content Protection (HDCP) scheme for the HDMI specification. HDCP is digital copy protection developed by Intel to prevent non-licensed devices from receiving content, encryption over HDMI/DVI/DisplayPort, and other restrictions in the name of content protection.

The patch enabling the HDMI HDCP support for Freedreno Gallium3D is currently being reviewed by the upstream developers and can be found on the dri-devel list.
