Re: [PATCH] powerpc/powernv: Add support for NPU2 relaxed-ordering mode

From: Alistair Popple <redacted>

Some device drivers support out of order access to GPU memory. This does
not affect the CPU view of memory but it does affect the GPU view, so it
should only be enabled once the GPU driver has requested it. Add APIs
allowing a driver to do so.

Do we have any indication which drivers we are expecting to use this?

I'd prefer not to merge a new API unless we at least have some idea
what's going to use it.
