commit 7062565efc0b7f74171338ee99b851bc48adcbfe Author: Aaron Durbin adurbin@chromium.org Date: Tue Oct 29 10:43:53 2013 -0500
rambi: don't mark graphics as write-combining
We are currently running out of MTRRs with this CPU when marking the graphics memory as write-combining. The reason is that the graphics stolen memory was bumped to 64MiB which changes the address space enough that the MTRRs are exhausted.
BUG=None BRANCH=None TEST=Built and analyzed MTRR usage. Also noted clearing upper 2GiB of memory in depthcharge does not take forever.
