So when a hypervisor starts supporting RAPL we'll disable the driver
erroneously?
Isn't there any better method to detect RAPL support?
So in particular in drivers/powercap/intel_rapl.c there's an enumerated list of
CPU models, which is used via a x86_match_cpu() call. That's still not ideal
(it
does not work on hypervisors for example), but even better would be to detect
RAPL
support in some other fashion, that does not rely on us statically enumerating
CPU
models that support it.
Thanks,
Ingo
