  • 8df0eb7c9   ACPI: Store SRAT table revision ... Browse Code »
    1

    In SRAT v1, we had 8bit proximity domain (PXM) fields; SRAT v2 provides
    32bits for these. The new fields were reserved before.
    According to the ACPI spec, the OS must disregrard reserved fields.
    In order to know whether or not, we must know what version the SRAT
    table has.

    This patch stores the SRAT table revision for later consumption
    by arch specific __init functions.

  • 3484d7981   x86_64: fake pxm-to-node mapping for fake numa ... Browse Code »

    For NUMA emulation, our SLIT should represent the true NUMA topology of the
    system but our proximity domain to node ID mapping needs to reflect the
    emulated state.

    When NUMA emulation has successfully setup fake nodes on the system, a new
    function, acpi_fake_nodes() is called. This function determines the proximity
    domain (_PXM) for each true node found on the system. It then finds which
    emulated nodes have been allocated on this true node as determined by its
    starting address. The node ID to PXM mapping is changed so that each fake
    node ID points to the PXM of the true node that it is located on.

    If the machine failed to register a SLIT, then we assume there is no special
    requirement for emulated node affinity so we use the default LOCAL_DISTANCE,
    which is newly exported to this code, as our measurement if the emulated nodes
    appear in the same PXM. Otherwise, we use REMOTE_DISTANCE.

    PXM_INVAL and NID_INVAL are also exported to the ACPI header file so that we
    can compare node_to_pxm() results in generic code (in this case, the SRAT
    code).

  • 8ff6f48d9   ACPI: Section mismatch ... acpi_map_pxm_to_node ... Browse Code »

    Last of the "Section mismatch" errors from ia64 builds! acpi_map_pxm_to_node()
    is defined with attribute __cpuinit, but is called by "normal" kernel functions
    acpi_getnode() and acpi_map_cpu2node().

    Commit f363d16fbb9374c0bd7f2757d412c287169094c9 moved the data structures on
    which this routine operates from __cpuinitdata to regular memory, so this
    routine can also move out of init space.

  • f363d16fb   acpi: fix potential call to a freed memory section. ... Browse Code »

    Strip __cpuinit[data] from Node PXM routines and supporting data
    structures. Also make pxm_to_node_map and node_to_pxm_map local to the
    numa acpi module.

    This fixes a bug triggered by the following conditions:
    - boot on a machine with a SLIT table defined
    - kernel is configured w/ CONFIG_HOTPLUG_CPU=n
    - cat /sys/devices/system/node/node*/distance
    This will cause an oops by calling into a freed memory section.

    In particular, on x86_64, __node_distance calls node_to_pxm().
