Subject: Re: [PATCH v2 1/5] drm-uapi/amdgpu: add UAPI query if user queues are supported

The series of 5 patches looks good to me. Just a small suggestion: please combine patches 3, 4, and 5 into a single patch, since they all relate to the usage of asic_userq_readiness and only touch three tests.
