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

devlink info versions implemented¶

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.
