.. SPDX-License-Identifier: GPL-2.0 ===================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 acombined 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.
