From ce0e22f5d886d1b56c7ab4347c45b9ac5fcc058d Mon Sep 17 00:00:00 2001 From: Louis Li Date: Sat, 25 May 2019 06:39:47 +0800 Subject: drm/amdgpu: fix ring test failure issue during s3 in vce 3.0 (V2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [What] vce ring test fails consistently during resume in s3 cycle, due to mismatch read & write pointers. On debug/analysis its found that rptr to be compared is not being correctly updated/read, which leads to this failure. Below is the failure signature: [drm:amdgpu_vce_ring_test_ring] *ERROR* amdgpu: ring 12 test failed [drm:amdgpu_device_ip_resume_phase2] *ERROR* resume of IP block failed -110 [drm:amdgpu_device_resume] *ERROR* amdgpu_device_ip_resume failed (-110). [How] fetch rptr appropriately, meaning move its read location further down in the code flow. With this patch applied the s3 failure is no more seen for >5k s3 cycles, which otherwise is pretty consistent.
