INTEL HYBRID SUPPORT
Support for Intel hybrid events within perf tools.
For some Intel platforms, such as AlderLake, which is hybrid
platform and it consists of atom cpu and core cpu. Each cpu has
dedicated event list. Part of events are available on core cpu,
part of events are available on atom cpu and even part of events
are available on both.
Kernel exports two new cpu pmus via sysfs: /sys/devices/cpu_core
/sys/devices/cpu_atom
The cpus files are created under the directories. For example,
cat /sys/devices/cpu_core/cpus 0-15
cat /sys/devices/cpu_atom/cpus 16-23
It indicates cpu0-cpu15 are core cpus and cpu16-cpu23 are atom
cpus.
