Does PAPI support Intel raptor lake CPU(have p-core and e-core)

[qi wang]

Hi :

Does anyone know whether PAPI support raptor lake CPU such as intel i7 14700k or not?

Because the raptor lake CPU has performance cores and efficiency cores, does PAPI know how to map counters to these two types of cores ? thanks a lot.

Best

there are some patches that get Raptor Lake support working on PAPI but
they have not all been merged upstream yet.

They've stalled a bit because to get proper hybrid support into PAPI
requires some fairly major re-writes to the low-level perf_event core
code.
