  • 7527a7b15   IB/core: Simplify rdma cgroup registration ... Browse Code »

    RDMA cgroup registration routine always returns success, so simplify
    function to be void and run clang formatter over whole CONFIG_CGROUP_RDMA
    art of core_priv.h.

    This reduces unwinding error path for regular registration and future net
    namespace change functionality for rdma device.

  • 7896dfb0a   rdmacg: Fixed uninitialized current resource usage ... Browse Code »

    Fixed warning reported by kbuild test robot.
    When reading current resource usage value, when no resources are
    allocated, its possible that it can report a uninitialized value
    for current resource usage.
    This fix avoids it by initializing it to zero as no resource is
    allocated.

  • 39d3e7584   rdmacg: Added rdma cgroup controller ... Browse Code »

    Added rdma cgroup controller that does accounting, limit enforcement
    on rdma/IB resources.

    Added rdma cgroup header file which defines its APIs to perform
    charging/uncharging functionality. It also defined APIs for RDMA/IB
    stack for device registration. Devices which are registered will
    participate in controller functions of accounting and limit
    enforcements. It define rdmacg_device structure to bind IB stack
    and RDMA cgroup controller.

    RDMA resources are tracked using resource pool. Resource pool is per
    device, per cgroup entity which allows setting up accounting limits
    on per device basis.

    Currently resources are defined by the RDMA cgroup.

    Resource pool is created/destroyed dynamically whenever
    charging/uncharging occurs respectively and whenever user
    configuration is done. Its a tradeoff of memory vs little more code
    space that creates resource pool object whenever necessary, instead of
    creating them during cgroup creation and device registration time.
