From: Sandy Stutsman <sstut...@redhat.com>
WDDM DOD driver doesn't touch the frame buffer (bar0), so no reason to map in
into memory.
Especially as there were rare BSOD failures when the mapping failed. Leaving
the code
in place so it clear where the frame buffer should be mapped if we need to do
it in the future.
