From e7b93cd9b3cbdcb0999eb91a89e81846948899fd Mon Sep 17 00:00:00 2001

Subject: [PATCH 3914/4256] 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.
