From 2c773de2ecb8c327f2448bd1eecad224e9227087 Mon Sep 17 00:00:00 2001 From: Shirish S Date: Mon, 16 Apr 2018 12:17:57 +0530 Subject: drm/amdgpu: defer test IBs on the rings at boot (V3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit amdgpu_ib_ring_tests() runs test IB's on rings at boot contributes to ~500 ms of amdgpu driver's boot time. This patch defers it and ensures that its executed in amdgpu_info_ioctl() if it wasn't scheduled. V2: Use queue_delayed_work() & flush_delayed_work(). V3: removed usage of separate wq, ensure ib tests is run before enabling clockgating.
