From df99ac0fcc507cb680c5b75b679cda1195a99a42 Mon Sep 17 00:00:00 2001 From: Jesse Zhang Date: Tue, 30 Jul 2019 19:15:42 +0800 Subject: drm/amd/amdgpu:Fix compute ring unable to detect hang. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When compute fence did not signal, compute ring cannot detect hardware hang because its timeout value is set to be infinite by default. In SR-IOV and passthrough mode, if user does not declare custome timeout value for compute ring, then use gfx ring timeout value as default. So that when there is a ture hardware hang, compute ring can detect it.
