For SMU v13.0.4/11, driver does not need to stop RLC for S0i3,
the firmwares will handle that properly.
Conceptually I'm aligned to this.
But, just to confirm, have you already run some testing with this
with current GPU F/W, BIOS and either 6.1.y, 6.4.y or ASDN?
I checked with this on my side and saw success but I'm fearful
that it introduces some of the fence expiration problems we
had in the past and I'm just not seeing them for some reason.
