the following patch was just integrated into master: commit 3549462a95c5d7b9450924a1c0ca54b992c81211 Author: Aaron Durbin adurbin@chromium.org Date: Wed Jan 15 11:59:10 2014 -0600
baytrail: enable graphics turbo
Though the limited documentation indicates the default is 0 for the gfx_turbo_disable bit, in practice that isn't true. Knock down the gfs_turbo_disable bit to enable graphics turbo mode.
BUG=chrome-os-partner:25044 BRANCH=baytrail TEST=Built and booted. Added debug code to output SB_BIOS_CONFIG. Noted that bit 7 was set to 0.
