Some newer x86 platforms have support for both _CPC and _PSS object. So
kernel config can have both ACPI_CPU_FREQ_PSS and ACPI_CPPC_LIB. So remove
restriction for ACPI_CPPC_LIB to build only when ACPI_CPU_FREQ_PSS is not
defined.
Also for legacy systems with only _PSS, we shouldn't bail out if

When a force mode bit is set and the IDDIG debounce filter is enabled,
there is a delay for the forced mode to take effect. This delay is due
to the IDDIG debounce filter and is variable depending on the platform's

This series accounts for the delay from the IDDIG debounce filter when

When the 'perf test -v vmlinux' test fails, it is not clear which of the

From: Arnaldo Carvalho de Melo
The algorithms used to prune aliases in symbols__fixup_duplicate() uses
information available on ELF symtabs that are not present on
/proc/kallsyms, so it picks different aliases as "best" for vmlinux and
kallsyms.
We could probably improve a bit this by having a l

When we call symbol__fixup_duplicate() we use algorithms to pick the
"best" symbols for cases where there are various functions/aliases to an
address, and those check zero size symbols, which, before calling

Introduce helper function instead of inline code and replace hardcoded
strings "$vars" and "$params" with their corresponding macros.
perf_probe_with_var() is not declared as static since it will be called
from different file in subsequent patch.

Add --definition/-D option for showing the trace-event definition in
stdout. This can be useful in debugging or combined with a shell script.

The symbols in the synthesized @plt entries where not demangled before,
