    Subject[PATCH 0/19] v6 multi-die/package topology support
    Date

    This patch series does 4 things.

    1. Parse the new CPUID.1F leaf to discover multi-die/package topology

    2. Export multi-die topology inside the kernel

    3. Update 4 places (coretemp, pkgtemp, rapl, perf) that that need to know
    the difference between die and package-scope MSR.

    4. Export multi-die topology to user-space via sysfs

    These changes should have no impact on cache topology,
    NUMA topology, Linux scheduler, or system performance.

    These topology changes primarily impact parts of the kernel
    and some applications that care about package MSR scope.
    Also, some software is licensed per package, and other tools,
    such as benchmark reporting software sometimes cares about packages.

    Changes since v5:

    The patch numbers have decremented by 3, since the first 3 patches
    in the original series are now upstream.

    The last two "Cosmetic rename" patches have been replaced with
    those by Kan, who did a more thorough variable rename than I had
    originally proposed.


    [PATCH 18/19] perf/x86/intel/uncore: Cosmetic renames in response to multi-die/pkg support
    [PATCH 19/19] perf/x86/intel/rapl: Cosmetic rename internal variables in response to multi-die/pkg support

    I'm not aware of any outstanding feedback on this series,
    functional or cosmetic.

    thanks,
    Len Brown, Intel Opensource Technology Center
