From a15a5065909f53d8f4ffefa9b54666628ae4fd4f Mon Sep 17 00:00:00 2001 From: Sandor Yu Date: Mon, 27 Aug 2012 10:25:02 +0800 Subject: [PATCH] ENGR00221444 HDMI: video mode wrong when bootup without HDMI cable Bootup Android without HDMI cable plugin, then plugin HDMI cable, video mode in /sys/class/graphics/fb0/mode not same as actually HDMI work video mode. The root cause is in video mode point to one of video mode in original video modelist, but the modelist will be updated when HDMI cable plug to new monitor. If HDMI original worked video mode can work on new monitor, the HDMI and framebuffer will not updated, so HDMI actually work mode not same as /sys/class/graphics/fb0/mode Updated fbi mode pointer even if video mode no changed in case moselist is updated, the issue will fixed.
