libpfm4's Issues

Clarify that this is a fork

FWIW, this is the top hit on Google for libpfm4 appearing before the actual project repo/pages. It might be useful to indicate that this is a fork/mirror (which is it?) in the project description in GitHub, to avoid confusion and prevent users from opening issues, etc.

Invalid event attribute for cpu_clk_unhalted.thread

Hello, I am getting the error: invalid event attribute for cpu_clk_unhalted.thread. However, I do get counter values which are in the expected range even though an error message is printed out. However, there is no error when I try cpu_clk_unhalted.thread_p instead.

The error occurs when calling this line:
ret = pfm_get_os_event_encoding(event, PFM_PLM3, PFM_OS_PERF_EVENT, &arg)) != PFM_SUCCESS

I use the following config:

    // clear all fields
    memset(&config, 0, sizeof(config));
    // common options across counters
    apply_default_options(&config);
    apply_required_options(&config);

uncore events visibility

Hi,

is there any way to display uncore events available for platform without actually digging into lib files? I mean something like pmu.py but actually containing stuff like unc icm? Like to get content of intel_skx_unc_imc_events.h

Could I have an example on how to use python to call libpfm4?
