Yeah, I know we have the counters defined in daemon.c. Martin reminded
me that Roy had a patch to remove that, sorry that I could not find the
link now. Another reason I did not use the nouveau_specsig is because I
had to create some nvif structures to access the counters and that's not
straightforward. I'm happy to hear you're fine with the on-host
implementation. :)
I will move all to PWR subdev in the next version.

So currently there is no dGPU using the PMU? I just don't want to break
any dGPU functions. ;)

BTW, can we add some execution time information for pstate? I mean
something like
"/sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state". I know we
don't want to change the user space ABI though.
Thanks,
