Tomas, Could you please help to review and give final "Go" for the series? Thanks --Ram. On 2/21/2019 11:41 PM, Ramalingam C wrote:
This series enables the HDCP2.2 Type 0 for I915. The sequence for HDCP2.2 authentication and encryption is implemented as a generic flow between HDMI and DP. Encoder specific implementations are moved into hdcp_shim. Intel HWs supports HDCP2.2 through ME FW. Hence this series introduces a client driver for mei bus, so that for HDCP2.2 authentication, HDCP2.2 stack in I915 can avail the services from ME FW. To enable this client driver set the config variable CONFIG_INTEL_MEI_HDCP. Userspace interface remains unchanged as version agnostic. When userspace request for HDCP enable, Kernel will detect the HDCP source and sink's HDCP version(1.4/2.2)capability and enable the best capable version for that combination. This series enables the HDCP2.2 for Type0 content streams. Test-with: <1549566452-30175-1-git-send-email-ramalingam.c@xxxxxxxxx> So that CP will be tested on BAT machine too. Major changes in v15 - All I915 patches are merged. So dropping them. - Few minor suggestions are incorporated at mei changes.
