I didn't realize it was already queued. Gmail threads failed me this time.
@Paolo Bonzini : Can you please drop this one as this will break as
soon as the host riscv system
has the latest kernel ? I have provided more details in the original thread.

If you have dynamic clock adjustment, does rdcycle increase with a fixed frequency or does it provide the raw number of clock cycles? If the latter, I agree that it should be provided by perf; but if the frequency is fixed then it would be the same as rdtsc on Intel.
