From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thierry Reding Subject: [PATCH] drm: tegra: Use framebuffer pitch as line stride Date: Thu, 22 Nov 2012 20:37:17 +0100 Message-ID: <1353613037-15808-1-git-send-email-thierry.reding@avionic-design.de> Return-path: Sender: linux-tegra-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Dave Airlie Cc: dri-devel-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org, linux-tegra-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Marc Dietrich List-Id: dri-devel@lists.freedesktop.org Instead of using the stride derived from the display mode, use the pitch associated with the currently active framebuffer. This fixes a bug where the LCD display content would be skewed when enabling HDMI with a video mode different from that of the LCD.
