From ba32836879c32b027adacf0bad4a5c62f22d2173 Mon Sep 17 00:00:00 2001 From: Alastair Bridgewater Date: Tue, 11 Apr 2017 13:11:21 -0400 Subject: [PATCH] drm/nouveau/disp/gt215: Use supplied HDMI InfoFrames Now that we have the InfoFrame data being provided, for the most part, program the hardware to use it. While we're here, and since the functionality will come in handy for supporting 3D stereoscopy, implement setting the Vendor ("generic") InfoFrame. Also don't enable any AVI or Vendor InfoFrame that is not provided, and disable the Vendor InfoFrame when disabling the output. Ignore the Audio InfoFrame: We don't supply it, and altering HDMI audio semantics (for better or worse) on this hardware is out of scope for me at this time.
