NAME
mlx5dv_create_mkey - Creates an indirect mkey mlx5dv_create_mkey - Destroys an indirect mkey
SYNOPSIS
#include <infiniband/mlx5dv.h> struct mlx5dv_mkey_init_attr { struct ibv_pd *pd; uint32_t create_flags; uint16_t max_entries; }; struct mlx5dv_mkey { uint32_t lkey; uint32_t rkey; }; struct mlx5dv_mkey * mlx5dv_create_mkey(struct mlx5dv_mkey_init_attr *mkey_init_attr); int mlx5dv_destroy_mkey(struct mlx5dv_mkey *mkey);
DESCRIPTION
Create / destroy an indirect mkey. Create an indirect mkey to enable application uses its specific device functionality.
ARGUMENTS
##mkey_init_attr## pd ibv protection domain. create_flags MLX5DV_MKEY_INIT_ATTR_FLAGS_INDIRECT: Indirect mkey is being created. max_entries Requested max number of pointed entries by this indirect mkey. The function will update the mkey_init_attr->max_entries with the actual mkey value that was created; it will be greater than or equal to the value requested.
RETURN VALUE
Upon success mlx5dv_create_mkey will return a new struct mlx5dv_mkey on error NULL will be returned and errno will be set. Upon success destroy 0 is returned or the value of errno on a failure.
Notes
To let this functionality works a DEVX context should be opened by using mlx5dv_open_device.
