Hi Shaoyun, You'd need to squash these 3 patches into 1 because otherwise you break the build.
But I think there should be a way to do this without requiring an interface change. In kgd_hqd_load you could remember the pipe_id and queue_id of the HIQ somewhere in adev. Then you can use that to detect when the HIQ is destroyed later without looking at the MQD.
