From 57084d05379fe5c081d024006129b0565a11855f Mon Sep 17 00:00:00 2001 From: James Simmons Date: Mon, 20 Dec 2010 19:10:39 +0000 Subject: drm/fb: Don't expose mmio for fbdev emulation layer For the fbdev api if the struct fb_var_screeninfo accel_flags field is set to FB_ACCELF_TEXT then userland applications can not mmap the mmio region. Since it is a bad idea for DRM drivers to expose the mmio region via the fbdev layer we always set the accel_flags to prevent this. Please apply.
