NAME         top

       mlx5dv_vfio_process_events - process vfio driver events

SYNOPSIS         top

              #include <infiniband/mlx5dv.h>

              int mlx5dv_vfio_process_events(struct ibv_context *ctx);

DESCRIPTION         top

       This API should run from application thread and maintain device
       events.  The application is responsible to get the events FD by
       calling mlx5dv_vfio_get_events_fd() and once the FD is pollable
       call the API to let driver process its internal events.

ARGUMENTS         top

       ctx    device context that was opened for VFIO by calling
              mlx5dv_get_vfio_device_list().

RETURN VALUE         top

       Returns 0 upon success or errno value in case a failure has
       occurred.

NOTES         top

       Application can use this API also to periodically check the device
       health state even if no events exist.
