From 4979904c62b9c0af492e679fb04f675ad5f238f2 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 18 Jan 2019 13:20:10 +0100 Subject: [PATCH] drm/qxl: use shadow bo directly MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Pass the shadow bo to qxl_io_create_primary() instead of expecting qxl_io_create_primary to check bo->shadow. Set is_primary flag on the shadow bo. Move the is_primary tracking into qxl_io_create_primary() and qxl_io_destroy_primary() functions. That simplifies primary surface tracking and the workflow in qxl_primary_atomic_update().
