Parameters

mkey
The returned MKey. MUST NOT BE NULL.

Returns

Parameters
pd
A protection domain that is not associated with any DOCA device
dev
A newly created DOCA device with same protection domain as 'pd'

Returns

DOCA_SUCCESS - in case of success

Description

Always prefer using a DOCA device obtained from doca_devinfo_create_list() This call will fail if PD was acquired by DOCA through doca_devinfo_create_list() and then doca_rdma_bridge_get_dev_pd()

This API should be used only to bridge between rdma-core and DOCA, to allow them to share memory registrations E.g., application already has logic that utilizes an ibv_pd, to read and write memory using RDMA, and wants to extend the logic by using libraries in DOCA, but such libraries will require a doca_dev and doca_buf instead of an ibv_pd and mkey in order to read write same memory. Then this method can be used to get a doca_dev that can be added to a doca_mmap, such that any doca_buf created from the doca_mmap can yield mkeys that are associated with the same ibv_pd using doca_rdma_bridge_get_buf_mkey()

For reference: doca_dev - is parallel to an ibv_pd doca_buf - is parallel to an ibv_mr registered on multiple devices doca_mmap - is parallel to creating an ibv_mr for multiple devices

The only APIs that are supported for the newly created device:

dev
A newly created DOCA device with same protection domain as 'pd'

Returns

DOCA_SUCCESS - in case of success

Description

Always prefer using a DOCA device obtained from doca_devinfo_create_list() This call will fail if PD was acquired by DOCA through doca_devinfo_create_list() and then doca_rdma_bridge_get_dev_pd()

This API should be used only to bridge between rdma-core and DOCA, to allow them to share memory registrations E.g., application already has logic that utilizes an ibv_pd, to read and write memory using RDMA, and wants to extend the logic by using libraries in DOCA, but such libraries will require a doca_dev and doca_buf instead of an ibv_pd and mkey in order to read write same memory. Then this method can be used to get a doca_dev that can be added to a doca_mmap, such that any doca_buf created from the doca_mmap can yield mkeys that are associated with the same ibv_pd using doca_rdma_bridge_get_buf_mkey()

For reference: doca_dev - is parallel to an ibv_pd doca_buf - is parallel to an ibv_mr registered on multiple devices doca_mmap - is parallel to creating an ibv_mr for multiple devices

The only APIs that are supported for the newly created device:

Client side Connect.
doca_error_t doca_comm_channel_ep_create ( doca_comm_channel_ep_t** ep )
