feat(metrics): Support heterogenous architectures with raw events #261

Closed cvonelm closed 1 year ago

cvonelm commented 1 year ago

As by their nature, there is no information about which CPUs are supported for any given raw event swimming somewhere in the kernel, the only solution to get the set of supported CPUs is good old trial-and-error

@tilsche can you verify that this PR has the desired effect? lo2s is able to measure the raw event now, but I can not verify if the measurement results make sense.
