From 2709b275c5d7ad01ae08cad004587f479aa3ea95 Mon Sep 17 00:00:00 2001 From: Alastair Bridgewater Date: Tue, 11 Apr 2017 13:11:22 -0400 Subject: [PATCH] drm/nouveau/disp/gf119: 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 InfoFrame that is not provided, and disable the Vendor InfoFrame when disabling the output.
