    Subject[PATCHv4 00/13] Heterogeneuos memory node attributes
    Date
    The series seems quite calm now. I've received some approvals of the
    on the proposal, and heard no objections on the new core interfaces.

    Please let me know if there is anyone or group of people I should request
    and wait for a review. And if anyone reading this would like additional
    time as well before I post a potentially subsequent version, please let
    me know.

    I also wanted to inquire on upstream strategy if/when all desired
    reviews are received. The series is spanning a few subsystems, so I'm
    not sure who's tree is the best candidate. I could see an argument for
    driver-core, acpi, or mm as possible paths. Please let me know if there's
    a more appropriate option or any other gating concerns.

    == Changes from v3 ==

    I've fixed the documentation issues that have been raised for v3

    Moved the hmat files according to Rafael's recommendation

    Added received Reviewed-by's

    Otherwise this v4 is much the same as v3.

    == Background ==

    Platforms may provide multiple types of cpu attached system memory. The
    memory ranges for each type may have different characteristics that
    applications may wish to know about when considering what node they want
    their memory allocated from.

    It had previously been difficult to describe these setups as memory
    rangers were generally lumped into the NUMA node of the CPUs. New
    platform attributes have been created and in use today that describe
    the more complex memory hierarchies that can be created.

    This series' objective is to provide the attributes from such systems
    that are useful for applications to know about, and readily usable with
    existing tools and libraries.

    acpi: Create subtable parsing infrastructure
    acpi: Add HMAT to generic parsing tables
    acpi/hmat: Parse and report heterogeneous memory
    node: Link memory nodes to their compute nodes
    Documentation/ABI: Add new node sysfs attributes
    acpi/hmat: Register processor domain to its memory
    node: Add heterogenous memory access attributes
    Documentation/ABI: Add node performance attributes
    acpi/hmat: Register performance attributes
    node: Add memory caching attributes
    Documentation/ABI: Add node cache attributes
    acpi/hmat: Register memory side cache attributes
    doc/mm: New documentation for memory performance
