they are unrelated. And for the other PR: pinned memory buys not a lot for upstream, but for ROCm.
For every KLE, we copy host -> device, but that has way more latency than pinned host -> device, at least for ROCm (maybe also because the host -> device path is more cluttered with OMPT and other stuff)
