From 2239e6dff2067c23f0afb7fab62ef139dc957d48 Mon Sep 17 00:00:00 2001 From: Daniele Ceraolo Spurio Date: Sat, 13 Jul 2019 11:00:15 +0100 Subject: [PATCH] drm/i915/guc: prefer intel_gt in guc interrupt functions We can get rid of a few more guc_to_i915 and start compartmentalizing interrupt management a bit more. We should be able to move more code in the future once the gt_pm code is also moved across to gt.
