From 777dbd458c89d4ca74a659f85ffb5bc817f29a35 Mon Sep 17 00:00:00 2001 From: Monk Liu Date: Tue, 26 Jan 2016 14:59:57 +0800 Subject: [PATCH] drm/amdgpu: drop a dummy wakeup scheduler MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit since the dependency job is also scheduled by the same scheduler with the job depended on it, no need to call wake up scheduler when the dep is scheduled.
