[Nouveau] Question on MME and Compute Subchannel in Kepler+

[Fernando Sahmkow]

Hello everyone,

I've been trying to adapt a switch emulator to emulate nouveau's compute.
We've been told some things like indirect dispatch use the MME in Nouveau,
however, looking at NVIDIA's open gpu documentation there's no MME in
compute engine since Kepler.
https://github.com/NVIDIA/open-gpu-doc/blob/master/classes/compute/clb1c0.h MME
for compute should still exist because of the presence of MME Shadow Memory
Scratch registers.

How does MME for Compute works on Kepler+ ? Does it use the 3D Subchannel?
if so how do I know when its targeting the Compute Subchannel?
