From dc755faef2640ea3d9ef3714c4ac5ece28bfe5a3 Mon Sep 17 00:00:00 2001 From: Piotr Piorkowski Date: Mon, 4 Jun 2018 16:19:43 +0200 Subject: [PATCH] drm/i915/guc: Refactoring preparation of the GUC_CTL_FEATURE parameter MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit At the moment, the preparation of GUC_CTL_FEATURE is disordered. Lets move all GUC_CTL_FEATURE related operations to one place.
