From e64c4a1b8a1fbf56cbeed794816e6587719fab5c Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Mon, 4 Nov 2013 19:45:44 -0800 Subject: [PATCH] drm/i915/bdw: Disable semaphores We've done insufficient testing on them thus far, so keep them disabled until we do test. v2: Use WARN when not enabling preliminary HW support as this should only be disabled for that case. v3: Rip out the now useless (and really noisy) DRM_INFO output.
