7 This document describes the devlink features implemented by the ``ice``
13 The ``ice`` driver reports the following versions
15 .. list-table:: devlink info versions implemented
25 - The Product Board Assembly (PBA) identifier of the board.
29 - 3-digit version number of the management firmware that controls the
34 - 2-digit version number of the API exported over the AdminQ by the
35 management firmware. Used by the driver to identify what commands
40 - Unique identifier of the source for the management firmware.
44 - Version of the Option ROM containing the UEFI driver. The version is
45 reported in ``major.minor.patch`` format. The major version is
46 incremented whenever a major breaking change occurs, or when the
47 minor version would overflow. The minor version is incremented for
48 non-breaking changes and reset to 1 when the major version is
49 incremented. The patch version is normally 0 but is incremented when
50 a fix is delivered as a patch against an older base Option ROM.
54 - Version defining the format of the flash contents.
58 - Unique identifier of the firmware image file that was loaded onto
59 the device. Also referred to as the EETRACK identifier of the NVM.
62 - ICE OS Default Package
63 - The name of the DDP package that is active in the device. The DDP
64 package is loaded by the driver during initialization. Each
65 variation of the DDP package has a unique name.
69 - The version of the DDP package that is active in the device. Note
70 that both the name (as reported by ``fw.app.name``) and version are
71 required to uniquely identify the package.
72 * - ``fw.app.bundle_id``
74 - Unique identifier for the DDP package loaded in the device. Also
75 referred to as the DDP Track ID. Can be used to uniquely identify
76 the specific DDP package.
80 - The version of the netlist module. This module defines the device's
81 Ethernet capabilities and default settings, and is used by the
82 management firmware as part of managing link and device
84 * - ``fw.netlist.build``
87 - The first 4 bytes of the hash of the netlist module contents.
92 The ``ice`` driver implements support for flash update using the
93 ``devlink-flash`` interface. It supports updating the device flash using a
94 combined flash image that contains the ``fw.mgmt``, ``fw.undi``, and
95 ``fw.netlist`` components.
97 .. list-table:: List of supported overwrite modes
102 * - ``DEVLINK_FLASH_OVERWRITE_SETTINGS``
103 - Do not preserve settings stored in the flash components being
104 updated. This includes overwriting the port configuration that
105 determines the number of physical functions the device will
107 * - ``DEVLINK_FLASH_OVERWRITE_SETTINGS`` and ``DEVLINK_FLASH_OVERWRITE_IDENTIFIERS``
108 - Do not preserve either settings or identifiers. Overwrite everything
109 in the flash with the contents from the provided image, without
110 performing any preservation. This includes overwriting device
111 identifying fields such as the MAC address, VPD area, and device
112 serial number. It is expected that this combination be used with an
113 image customized for the specific device.
115 The ice hardware does not support overwriting only identifiers while
116 preserving settings, and thus ``DEVLINK_FLASH_OVERWRITE_IDENTIFIERS`` on its
117 own will be rejected. If no overwrite mask is provided, the firmware will be
118 instructed to preserve all settings and identifying fields when updating.
123 The ``ice`` driver implements the following regions for accessing internal
126 .. list-table:: regions implemented
132 - The contents of the entire flash chip, sometimes referred to as
133 the device's Non Volatile Memory.
135 - The contents of the device firmware's capabilities buffer. Useful to
136 determine the current state and configuration of the device.
