| 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. |
