rdma dev help
rdma dev set - rename RDMA device or set network namespace or set RDMA
device adaptive-moderation
rdma dev show - display RDMA device attributes
DEV - specifies the RDMA device to show. If this argument is
omitted all devices are listed.
rdma dev add - Add a RDMA device with a specific type and parent IB
device; This new device provides subset of functionalities defined
in IBTA spec.
rdma dev delete - Delete a RDMA device which is created with the add
command.
NAME - The name of the device being added/deleted.
TYPE - The type of the device being added; It specifies which
functionalities it provides. Supported device type:
SMI - A device with this type provides SMI (QP0)
interface. This device and it's parent associates with the
same HCA port and shares the physical link, so when the
parent doesn't support SMI, then this type of device can
be created to allow the subnet manager to configure the
link.
PARENT_DEV - The name of its parent IB device.
rdma dev
Shows the state of all RDMA devices on the system.
rdma dev show mlx5_3
Shows the state of specified RDMA device.
rdma dev set mlx5_3 name rdma_0
Renames the mlx5_3 device to rdma_0.
rdma dev set mlx5_3 netns foo
Changes the network namespace of RDMA device to foo where foo
is previously created using iproute2 ip command.
rdma dev set mlx5_3 adaptive-moderation [on/off]
Sets the state of adaptive interrupt moderation for the RDMA
device.
This is a global setting for the RDMA device but the value is
printed for each CQ individually because the state is constant
from CQ allocation.
rdma dev add smi1 type SMI parent ibp8s0f1
Add a new IB device with name "smi1", type "SMI", and
"ibp8s0f1" as its parent device.
rdma dev delete smi1
Delete the IB device "smi1".
