From 4dbb542d9923f0c98d1625bcdd2470d5bc6b0149 Mon Sep 17 00:00:00 2001 From: emaste Date: Tue, 2 Sep 2014 19:56:37 +0000 Subject: MFC r268771, r268796 by nwhitehorn: r268771: Allow console drivers active from early boot to be used with xf86-video-scfb, rather than only drivers attached later on. This involves a small amount of code duplication with dev/fb/fbd.c, which will fixed later on. Also improve performance of vt_blank() by making it not read from the framebuffer unnecessarily. r268796: Fix embarassing typos I made.
