So the documentation is not clear. However, our experience with the other SKUs of BYT-I/M on Android and Linux suggests that setting this bit actually causes GPU hang for certain OGL benchmark applications. Removing this bit completely resolves the GPU hangs. Signed-off-by: Sinclair Yeh Acked-by: Jesse Barnes Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
