    Subject[PATCH 00/12] perf: introduce model specific events and AMD IBS
    This patch series introduces model specific events and impments AMD
    IBS (Instruction Based Sampling) for perf_events.

    IBS is documented here:

    BIOS and Kernel Developer’s Guide (BKDG) For AMD Family 10h Processors

    AMD64 Architecture Programmer’s Manual Volume 2: System Programming

    The general approach is to introduce a flag to mark an event as model
    specific. With that flag set a model specific ibs (raw) config value
    can be passed to the pmu for setup. When there are ibs samples
    available, it is sent back as a raw data sample to the userland. So we
    have a raw config value and raw sampling data. This requires the
    userland to setup ibs and further extract and process sampling data.

    Patches 1-8 rework and refactor the code to prepare the ibs
    implementation. This is done in patches 9-12.

    I will add ibs example code to libpfm4.
