SYNOPSIS
              #include <infiniband/mlx5dv.h>

              int mlx5dv_devx_subscribe_devx_event(struct mlx5dv_devx_event_channel *dv_event_channel,
                                   struct mlx5dv_devx_obj *obj,
                                   uint16_t events_sz,
                                   uint16_t events_num[],
                                   uint64_t cookie)

              int mlx5dv_devx_subscribe_devx_event_fd(struct mlx5dv_devx_event_channel *dv_event_channel,
                                  int fd,
                                  struct mlx5dv_devx_obj *obj,

DESCRIPTION
       Subscribe over a DEVX event channel for device events.

ARGUMENTS
       dv_event_channel
              Event channel to subscribe over.

       fd     A file descriptor that previously was opened by the eventfd()
              system call.

       obj    DEVX object that events_num relates to, can be NULL for
              unaffiliated events.

       events_sz
              Size of the events_num buffer that holds the events to subscribe
              for.

       events_num
              Holds the required event numbers to subscribe for, numbers are
              according to the device specification.

       cookie The value to be returned back when reading the event, can be
              used as an ID for application use.

NOTES
       When mlx5dv_devx_subscribe_devx_event_fd will be used the fd will be
       signaled once an event has occurred.
