Ok, here's v2 of the HDCP patchset, no longer RFC since I've tackled the TODO list I set out in the first version (Annotated below for convenience). The big changes to take note of in v2 is locking. To account for atomic async + the property's mutability, I'm using a dedicated mutex and moved property setting on the kernel side to the worker. I think this is actually a lot easier to read, and it opens the door to future improvements such as not doing the enable/disable via modeset. TODO: - DONE: Add kerneldoc for property - DONE: Fix '//' comments - DONE: Change to MIT license - DONE: Improve documentation on drm_intel_hdcp_shim - DONE: Fix async commit locking (ie: don't use connection_mutex) - DONE: Don't change connector->state in enable, defer to worker - Rebase on Ville's gmbus fixes (thanks Ville) - Looks like these haven't landed, but I've rebased on drm-intel-next - Add igt coverage for the feature. - Working on this now Thanks!
