From b6445e17799d931c8c94e5d7acc59c9558f52df5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jakub=20Bartmi=C5=84ski?= Date: Fri, 27 Jul 2018 16:11:44 +0200 Subject: [PATCH] drm/i915/guc: Do not partition WOPCM if GuC is not used MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There seems to be no reason for doing extra work on WOPCM partitioning in the case GuC is not used, as the partitioning will not be used by the intel_wopcm_init_hw function anyway.
