From 95a9b8d10cb0ee78c1eb81ea51eeaf94be479416 Mon Sep 17 00:00:00 2001 From: Daniel Thompson Date: Fri, 17 Oct 2014 16:48:54 +0100 Subject: [PATCH] drm/msm: Fix fbdev for 16- and 24-bit modes. Currently forcing the video mode from the kernel command line (for example video=HDMI-A-1:1280x720-16@60) does not correctly set the number of bits per pixel. This is due to a rather aggressive override in msm_fbdev_create(). This is a particular problem for Android bring up because the software EGL fallbacks don't support 32bpp. Since the overrides are actually the default values anyway then this problem can be trivially fixed by removing the overrides completely. Change was tested by dd'ing a test image to /dev/fb0 with no video= (still 32bpp), video=1920x1080-32@60, video=1920x1080-24@60 and video=1920x1080-16@60 .
