From b489622a1fc8514eebb53428faa59dfea2203fc1 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 29 Oct 2013 10:43:53 -0500 Subject: [PATCH] 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.
