Subject: perf/x86/rapl: Move the cntr_mask to rapl_pmus struct
|
|
|
|
Prepare for the addition of RAPL core energy counter support.
|
|
|
|
Move cntr_mask to rapl_pmus struct instead of adding a new global
|
|
cntr_mask for the new RAPL power_core PMU. This will also ensure that
|
|
the second "core_cntr_mask" is only created if needed (i.e. in case of
|
|
AMD CPUs).
