After commit ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf"),
on AMD processors that support extended CPUID leaf 0x80000026, the
topology_die_cpumask() and topology_logical_die_id() macros, no longer
return the package cpumask and package id, instead they return the CCD
(Core Complex Die) mask and id respectively. This leads to the energy-pkg
event scope to be modified to CCD instead of package.
Replacing these macros with their package counterparts fixes the
energy-pkg event for AMD CPUs.
However due to the difference between the scope of energy-pkg event for
Intel and AMD CPUs, we have to replace these macros conditionally only for
AMD CPUs.
On a 12 CCD 1 Package AMD Zen4 Genoa machine:
Before:
$ cat /sys/devices/power/cpumask
0,8,16,24,32,40,48,56,64,72,80,88.
The expected cpumask here is supposed to be just "0", as it is a package
scope event, only one CPU will be collecting the event for all the CPUs in
the package.
After:
$ cat /sys/devices/power/cpumask
0

Changes in v4:
* Invert the pkg scope check in init_rapl_pmus() (Peter)
* Add comments to explain the pkg scope check (Peter)
PS: Scope check logic is still kept the same (i.e., all Intel systems being
considered as die scope), Rui will be modifying it to limit the die-scope
only to Cascadelake-AP in a future patch on top of this patchset.

2.34.1Hello Peter, Rui,
After Ian's comments on the series, I have decided to rethink the approach of
adding a new PMU for the per-core RAPL counters.
However this patch is still needed as a fix for the
commit ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf"), I will be
sending this separately along with a similar fix for powercap/intel_rapl_common.
Thanks,
Dhananjay

I didnt forget this time, just wanted to give you a chance to review the changes :) (although they are minimal)
Will surely add it in next version!
