Do they exist when booting a baremetal kernel?


Thank you f= or your response.


Does=A0booting a = baremetal kernel means booting Dom0?
If it means so, =A0they don't exist.

They = exist when booting a baremetal kernel.

Ok, then the answer is that nobody has looked in a long time (I think since 2.6.18) to hook up the oprofile (or rather the code that that gets invoked when a perf counter is triggered) to the Xen hypervisor. It might make sense to look at how 2.6.18 did it (especially what were the hypercalls and where) and see how to port it over to a pvops kernel.
