- ===================
- 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.
