drm/amdgpu: make IB test synchronize with init for SRIOV(v2)
issue: originally we kickoff IB test asynchronously with driver's init, thus the IB test may still running when the driver loading done (modprobe amdgpu done). if we shutdown VM immediately after amdgpu driver loaded then GPU may hang because the IB test is still running fix: flush the delayed_init routine at the bottom of device_init to avoid driver loading done prior to the IB test completes Signed-off-by: Monk Liu <> Acked-by: Christian K├Ânig <> Signed-off-by: Alex Deucher <>
