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

  • 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.
