ice devlink support¶
This document describes the devlink features implemented by the ice
device driver.
Info versions¶
The ice driver reports the following versions
| Name | Type | Example | Description |
board.id |
fixed | K65390-000 | The Product Board Assembly (PBA) identifier of the board. |
fw.mgmt |
running | 2.1.7 | 3-digit version number of the management firmware that controls the PHY, link, etc. |
fw.mgmt.api |
running | 1.5 | 2-digit version number of the API exported over the AdminQ by the management firmware. Used by the driver to identify what commands are supported. |
fw.mgmt.build |
running | 0x305d955f | Unique identifier of the source for the management firmware. |
fw.undi |
running | 1.2581.0 | Version of the Option ROM containing the UEFI driver. The version is
reported in major.minor.patch format. The major version is
incremented whenever a major breaking change occurs, or when the
minor version would overflow. The minor version is incremented for
non-breaking changes and reset to 1 when the major version is
incremented. The patch version is normally 0 but is incremented when
a fix is delivered as a patch against an older base Option ROM. |
fw.psid.api |
running | 0.80 | Version defining the format of the flash contents. |
fw.bundle_id |
running | 0x80002ec0 | Unique identifier of the firmware image file that was loaded onto the device. Also referred to as the EETRACK identifier of the NVM. |
fw.app.name |
running | ICE OS Default Package | The name of the DDP package that is active in the device. The DDP package is loaded by the driver during initialization. Each variation of the DDP package has a unique name. |
fw.app |
running | 1.3.1.0 | The version of the DDP package that is active in the device. Note
that both the name (as reported by fw.app.name) and version are
required to uniquely identify the package. |
Regions¶
The ice driver enables access to the contents of the Non Volatile Memory
flash chip via the nvm-flash region.
Users can request an immediate capture of a snapshot via the
