Intel Alder/Raptor Lake P-cores and E-cores

[mlurbe97]

I'm unable to program events on this platforms using the provided function
pcm_c_build_core_event(event_id, event_name)
inside a C code due to there are different events on each type of cores (P and E cores).

Maybe a similar function should be implemented to program events per core
pcm_c_build_core_event_on_core(cpu_id, event_id, event_name)
or a warning should be shown.

Now I'm having 0s on E cores when configuring events for P cores, and viceversa. It could be interesting to monitor similar events on both.

to program P-cores and E-cores events separately you can try to use a different PCM::program interface with ExtendedCustomCoreEventDescription structure as a parameter:

pcm/src/cpucounters.h

Line 859 in 0cbcdbe

struct ExtendedCustomCoreEventDescription

It has a separate Atom/E-core event config field:

pcm/src/cpucounters.h

Line 864 in 0cbcdbe

EventSelectRegister * gpCounterHybridAtomCfg; // general purpose counters for Atom cores in hybrid processors
