The legacy ACPI hardware P-States function has 3 P-States on ACPI table,
the CPU frequency only can be switched between the 3 P-States. While the
processor supports the boost state, it will have another boost state
that the frequency can be higher than P0 state, and the state can be
decoded by the function of decode_pstates() and read by
amd_pci_get_num_boost_states().
However, the new AMD P-State function is different than legacy ACPI
hardware P-State on AMD processors. That has a finer grain frequency
range between the highest and lowest frequency. And boost frequency is
actually the frequency which is mapped on highest performance ratio. The
similar previous P0 frequency is mapped on nominal performance ratio.
If the highest performance on the processor is higher than nominal
performance, then we think the current processor supports the boost
state. And it uses amd_pstate_boost_init() to initialize boost for AMD
P-State function.

The option `--to-ctf` is only available when perf has libbabeltrace
support. Hence, on error, we shouldn't state that user must include
`--to-ctf` unless it's supported.
The only user-visible change for this commit is that when `perf` is not
configured to support libbabeltrace, the user is only prompted to
provide the `--to-json` option instead of bothe `--to-json` and
`--to-ctf`.

In SPE traces the 'weight' field can't be printed in 'perf script'
because the 'dummy:u' event doesn't have the WEIGHT attribute set.
Use evsel__do_check_stype(..) to check this field, as it's done with
other fields such as "phys_addr".
Before:
$ perf record -e arm_spe_0// -- sleep 1
$ perf script -F event,ip,weight
Samples for 'dummy:u' event do not have WEIGHT attribute set. Cannot print 'weight' field.
After:
$ perf script -F event,ip,weight
