From 9a69b885e964cf93064f1a16ddd06ebb7d46ac17 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Fri, 23 Nov 2012 12:09:27 -0200 Subject: [PATCH] drm/i915: set the VIC of the mode on the AVI InfoFrame We currently set "0" as the VIC value of the AVI InfoFrames. According to the specs this should be fine and work for every mode, so to my point of view we can't consider the current behavior as a bug. The problem is that we recently received a bug report (Kernel bug #50371) from a user that has an AV receiver that gives a black screen for any mode with VIC set to 0. So in order to make at least some modes work for him, this patch sets the correct VIC number when sending AVI InfoFrames.
