Patchset enhance current runtime parameter support. It introduces new
fields like "PerChip" and "PerCore" similar to the field "PerPkg" which is
used to specify perpkg events.
The "PerCore" and "PerChip" specifies whether its core or chip events.
Based on which we can decide which runtime parameter user want to
access. Now character '?' can refers different parameter based on user
requirement.

Some nits) Could we document perchip and percore? Agreed that the style here is not to comment. I'm a little confused as to why these need to be const char* and can't just be a bool? Perhaps other variables shouldn't be const char* too. Is there ever a case where both perchip and percore could be true? Would something like an enum capture this better? I can imagine other cases uncore and it seems a little strange to add a new "const char*" each time. I'm wondering if there needs to be a glossary of terms, so that the use of terms like core, chip, thread, socket, cpu, package is kept consistent. It's not trivially clear what the difference between a chip and a socket is, for example. Mapping terms to other vendors commonly used terms, such as "complex" would also be useful.

You are right adding new parameter each time will not be good way to go. So, there won't be a case where both perchip/percore will be enabled. Hence we can add something like enum to capture the data. I work on prototype of adding all terms like percore, perchip, perpkg as part of enum. Now in future if we need to add new terms like thread, cpu etc. We just need to add that part in enum without creating new parameter each time. Please let me know any reviews on that. diff --git a/tools/perf/arch/powerpc/util/header.c b/tools/perf/arch/powerpc/util/header.c index d4870074f14c..5220b28a35a1 100644 --- a/tools/perf/arch/powerpc/util/header.c +++ b/tools/perf/arch/powerpc/util/header.c @@ -47,8 +47,11 @@ get_cpuid_str(struct perf_pmu *pmu __maybe_unused) return bufp;
