From f093f182ace9ce3c618c110e316cc1e22d0c9d3b Mon Sep 17 00:00:00 2001 From: Colin Xu Date: Mon, 11 Jun 2018 15:39:35 +0800 Subject: [PATCH] drm/i915/gvt: Enable cmd_parser support for BXT. Handle BXT cmd_parser as SKL/KBL. v2: All supported platforms share the same routines. Remove the platform check by now and let is_supported_device() be the gate keeper.
