From a37cfa8be20c5571ca82fac38441592040a2d071 Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Sat, 16 Jul 2016 17:00:44 +0530 Subject: [PATCH] drm/radeon: Remove deprecated create_singlethread_workqueue MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit alloc_workqueue replaces deprecated create_singlethread_workqueue(). Each hardware CRTC has a single flip work queue. When a radeon_flip_work_func item is queued, it needs to be executed ASAP because even a slight delay may cause the flip to be delayed by one refresh cycle. Hence, a dedicated workqueue with WQ_HIGHPRI set, has been used here since a delay can cause the outcome to miss the refresh cycle. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary here.
