sfc devlink support
===================
This document describes the devlink features implemented by the ``sfc``
device driver for the ef10 and ef100 devices.
Info versions
=============
The ``sfc`` driver reports the following versions
.. list-table:: devlink info versions implemented
:widths: 5 5 90
* - Name
- Type
- Description
* - ``fw.bundle_id``
- stored
- Version of the firmware "bundle" image that was last used to update
multiple components.
* - ``fw.mgmt.suc``
- running
- For boards where the management function is split between multiple
control units, this is the SUC control unit's firmware version.
* - ``fw.mgmt.cmc``
- running
- For boards where the management function is split between multiple
control units, this is the CMC control unit's firmware version.
* - ``fpga.rev``
- running
- FPGA design revision.
* - ``fpga.app``
- running
- Datapath programmable logic version.
* - ``fw.app``
- running
- Datapath software/microcode/firmware version.
* - ``coproc.boot``
- running
- SmartNIC application co-processor (APU) first stage boot loader version.
* - ``coproc.uboot``
- running
- SmartNIC application co-processor (APU) co-operating system loader version.
* - ``coproc.main``
- running
- SmartNIC application co-processor (APU) main operating system version.
* - ``coproc.recovery``
- running
- SmartNIC application co-processor (APU) recovery operating system version.
* - ``fw.exprom``
- running
- Expansion ROM version. For boards where the expansion ROM is split between
multiple images (e.g. PXE and UEFI), this is the specifically the PXE boot
ROM version.
* - ``fw.uefi``
- running
- UEFI driver version (No UNDI support).
Flash Update
============
The ``sfc`` driver implements support for flash update using the
``devlink-flash`` interface. It supports updating the device flash using a
combined flash image ("bundle") that contains multiple components (on ef10,
typically ``fw.mgmt``, ``fw.app``, ``fw.exprom`` and ``fw.uefi``).
The driver does not support any overwrite mask flags.
