Sadly stifb then crashes at bootup. Please include this copy&pasted hunk in this patch, which then fixes the crash: diff --git a/drivers/video/fbdev/stifb.c b/drivers/video/fbdev/stifb.c index 2de0e675fd15..f8bbd8d6f5b2 100644 --- a/drivers/video/fbdev/stifb.c +++ b/drivers/video/fbdev/stifb.c @@ -1158,7 +1158,7 @@ stifb_init_display(struct stifb_info *fb) } break; } - stifb_blank(0, (struct fb_info *)fb); /* 0=enable screen */ + stifb_blank(0, fb->info); /* 0=enable screen */ With this applied, you may add to the series: Tested-by: Helge Deller <deller@gmx.de> Reviewed-by: Helge Deller <deller@gmx.de> Thanks!

Allocate stifb's instance of fb_info with framebuffer_alloc(). This is the preferred way of creating fb_info with associated driver data stored in struct fb_info.par. Requires several, but minor, changes through out the driver's code. The intended side effect of this patch is that the new instance of struct fb_info now has its device field correctly set to the parent device of the STI ROM. A later patch can detect if the device is the firmware's primary output. It is also now correctly located within the Linux device hierarchy.
