Nouveau does not suspend my discrete GPU if idle. However bbswitch (nouveau
unloaded) is capable to suspend the GPU. I am running the 4.9.24 linux kernel.

My GPU: NVIDIA Corporation GM204M [GeForce GTX 970M] (rev ff)

Nouveau was capable to switch off the discrete GPU until kernel 4.7.
Starting with 4.8 it stopped working.

Hope we can get this fixed. Thanks!
