Here's the RFC for my i915 HDCP patchset. The UABI is based on what we've been using in Chrome for the past 3 years. I posted the property to the list back then, but never had a mainline driver to implement it. I do now :-)
Things are mostly in place, danvet gave me some feedback that I will incorporate in v1. However, in the interest of gaining more early feedback, I'm posting this now.
TODO: - Add kerneldoc for property - Fix '//' comments - Change to MIT license - Rebase on Ville's gmbus fixes (thanks Ville) - Improve documentation on drm_intel_hdcp_shim - Fix async commit locking (ie: don't use connection_mutex) - Don't change connector->state in enable, defer to worker - Add igt coverage for the feature.
Thanks!
Sean
