mlx5dv_devx_cr...y_event_channel(3) mlx5dv_devx_cr...y_event_channel(3)
mlx5dv_devx_create_event_channel - Create an event channel to be
used for DEVX asynchronous events.
mlx5dv_devx_destroy_event_channel - Destroy a DEVX event channel.
#include <infiniband/mlx5dv.h>
struct mlx5dv_devx_event_channel {
int fd;
};
struct mlx5dv_devx_event_channel *
mlx5dv_devx_create_event_channel(struct ibv_context *context,
enum mlx5dv_devx_create_event_channel_flags flags)
void mlx5dv_devx_destroy_event_channel(struct mlx5dv_devx_event_channel *event_channel)
Create or destroy a channel to be used for DEVX asynchronous
events.
The create verb exposes an mlx5dv_devx_event_channel object that
can be used to read asynchronous DEVX events. This lets an
application to subscribe to get device events and once an event
occurred read it from this object.
context
RDMA device context to create the channel on.
flags MLX5DV_DEVX_CREATE_EVENT_CHANNEL_FLAGS_OMIT_EV_DATA: omit
the event data on this channel.
Upon success mlx5dv_devx_create_event_channel will return a new
struct mlx5dv_devx_event_channel object, on error NULL will be
returned and errno will be set.
