Sean, We might want to check the panel's HDCP capability? Agreed that majority of HDMI/DP panel's supports it, but there is a possibility that we might avoid authentication on non-hdcp panels. As per HDCP specification, check for valid bksv will serve the purpose. On Thursday 30 November

This patch adds HDCP support for HDMI connectors by implementing the intel_hdcp_shim. Nothing too special, just a bunch of DDC reads/writes. Signed-off-by: Sean Paul --- drivers/gpu/drm/i915/i915_reg.h | 1 + drivers/gpu/drm/i915/intel_ddi.c | 50
