From: Michal Wajdeczko Date: Tue, 20 Mar 2018 18:14:19 +0000 Subject: drm/i915/guc: Move enable/disable msg functions to GuC header MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Git-commit: bc598425eb18d40a18f18d67f7c460189c43a3af Patch-mainline: v4.18-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 While today we are modifying GuC enabled msg mask only in GuC log, this code should be defined as generic GuC to allow future code reuse.
