Since for one hw event, two hybrid events are created.
For example,
evsel->idx evsel__name(evsel)
0 cycles
1 cycles
2 instructions
3 instructions
...
So for comparing the evsel name on hybrid, the evsel->idx
needs to be divided by 2.
Since for "cycles:u' on hybrid platform, it creates two "cycles".
So the number of events in evlist is not expected in next test
steps. Now we just use one event "cpu_core/cycles:u/" for hybrid.

The challenge is their available cpus are not fully matched.

For a hybrid system, the perf subsystem doesn't know which PMU the

perf-stat has supported some aggregation modes, such as --per-core,

It would be useful to tell user the pmu which the event belongs to.

fwnode_mdiobus_register() internally takes care of both DT
and ACPI cases to register mdiobus. Replace existing
of_mdiobus_register() with fwnode_mdiobus_register().
Note: For both ACPI and DT cases, endianness of MDIO controller
need to be specified using "little-endian" property.
