> -----Original Message-----

> The "arm,armv8-pmuv3" compatible is intended only for s/w models.
> Primarily, it doesn't provide any detail on uarch specific events.
> 
> There's still remaining cases for CPUs without any corresponding PMU
> definition and for big.LITTLE systems which only have a single PMU node
> (there should be one per core type).
