Intel IDPF device driver
|
|
========================
|
|
|
|
Overview
|
|
--------
|
|
|
|
This plugins provides native device support for Intel Infrastructure
|
|
Data Path Function (IDPF). The current IDPF is a driver specification
|
|
for future Intel Physical Function devices. IDPF defines communication
|
|
channel between Data Plane (DP) and Control Plane (CP).
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
- Driver requires MSI-X interrupt support, which is not supported by
|
|
uio_pci_generic driver, so vfio-pci needs to be used. On systems
|
|
without IOMMU vfio driver can still be used with recent kernels which
|
|
support no-iommu mode.
|
|
|
|
Known issues
|
|
------------
|
|
|
|
- This driver is still in experimental phase, and the corresponding device
|
|
is not released yet.
|
|
|
|
- Current version only supports device initialization. Basic I/O function
|
|
will be supported in the next release.

Usage
|
|
-----
|
|
|
|
Interface Creation
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
Interfaces can be dynamically created by using following CLI:
|
|
|
|
::
|
|
|
|
create interface idpf 0000:4b:00.0 vport-num 1 rx-single 1 tx-single 1
|
|
set int state idpf-0/4b/0/0 up
|
|
|
|
vport-num: number of vport to be created. Each vport is related to one netdev.
|
|
rx-single: configure Rx queue mode, split queue mode by default.
|
|
tx-single: configure Tx queue mode, split queue mode by default.
|
|
|
|
Interface Deletion
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
Interface can be deleted with following CLI:
|
|
|
|
::
|
|
|
|
delete interface idpf <interface name>
|
|
|
|
Interface Statistics
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Interface statistics can be displayed with
|
|
``sh hardware-interface <if-name>`` command.
