From b829e011f6f9eed8c4dd41eaf02bdbb3a3ad837f Mon Sep 17 00:00:00 2001 From: Adam Jackson Date: Thu, 10 Jun 2010 13:33:26 -0400 Subject: [PATCH] drm/fb: Fix video= mode computation Reduced blanking is valid only when doing CVT modes. Also, generate GTF modes unless CVT was requested; CVT devices are required to support GTF, but the reverse is not true.
