  • 390d57728   RDMA/core: Make rdma_counter.h compile stand alone ... Browse Code »

    5.4-rc1 will have new compile time debugging to test that headers can be
    compiled stand alone. Many rdma headers are already broken and excluded
    from the mechanism, however to avoid compile failures during the merge
    window fix enough so that the newly added header compiles clean.

  • 1bd8e0a9d   RDMA/counter: Allow manual mode configuration support ... Browse Code »

    In manual mode a QP is bound to a counter manually. If counter is not
    specified then a new one will be allocated.

    Manual mode is enabled when user binds a QP, and disabled when the last
    manually bound QP is unbound.

    When auto-mode is turned off and there are counters left, manual mode is
    enabled so that the user is able to access these counters.

  • f34a55e49   RDMA/core: Get sum value of all counters when perform a sysfs stat read ... Browse Code »

    Since a QP can only be bound to one counter, then if it is bound to a
    separate counter, for backward compatibility purpose, the statistic value
    must be:
    * stat of default counter
    + stat of all running allocated counters
    + stat of all deallocated counters (history stats)

  • 99fa331dc   RDMA/counter: Add "auto" configuration mode support ... Browse Code »

    In auto mode all QPs belong to one category are bind automatically to a
    single counter set. Currently only "qp type" is supported.

    In this mode the qp counter is set in RST2INIT modification, and when a qp
    is destroyed the counter is unbound.

  • 7ade1ff96   RDMA/restrack: Introduce statistic counter ... Browse Code »

    Introduce statistic counter as a new resource. It allows a user to monitor
    specific objects (e.g., QPs) by binding to a counter.

    In some cases a user counter resource is created with task other then
    "current", because its creation is done as part of rdmatool call.
