Hmm... I have here an imx6dl based system, and it draws two logos when booting... I can prevent this two logos, if I do:
diff --git a/drivers/video/fbdev/core/fbmem.c b/drivers/video/fbdev/core/fbmem.c index 0705d88..e907ab9 100644 --- a/drivers/video/fbdev/core/fbmem.c +++ b/drivers/video/fbdev/core/fbmem.c @@ -664,8 +672,7 @@ int fb_show_logo(struct fb_info *info, int rotate) { int y;
- y = fb_show_logo_line(info, rotate, fb_logo.logo, 0, - num_online_cpus()); + y = fb_show_logo_line(info, rotate, fb_logo.logo, 0, 1); y = fb_show_extra_logos(info, y, rotate);
return y; >> Hmm... I do not really have a lot experience in this area ... but why >> is the logo only drawed when booting?

I don;t know, it was just a question ... If this is not possible, we do not need to cover such a case, good!
