New Revision: 268771
URL: http://svnweb.freebsd.org/changeset/base/268771
Log:
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.
