History

Richard Hughes 40cd18fa97 Allow using a per-device global percentage completion It's actually quite hard to build a front-end for fwupd at the moment as you're never sure when the progress bar is going to zip back to 0% and start all over again. Some plugins go 0..100% for write, others go 0..100% for erase, then again for write, then again for verify. By creating a helper object we can easily split up the progress of the specific task, e.g. write_firmware(). We can encode at the plugin level "the erase takes 50% of the time, the write takes 40% and the read takes 10%". This means we can have a progressbar which goes up just once at a consistent speed.		2021-09-13 14:28:15 +01:00

Flashrom

Introduction

This plugin uses flashrom to update the system firmware.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format, which is typically the raw input for an EEPROM programmer.

This plugin supports the following protocol ID:

org.flashrom

Coreboot Version String

The coreboot version string can have an optional prefix (see below). After the optional prefix the major, minor string follows and finally the build string, containing the exact commit and repository state, follows.

For example 4.10-989-gc8a4e4b9c5-dirty

Exception on Lenovo devices

The thinkpad_acpi kernel module requires a specific pattern in the DMI version string. To satisfy those requirements coreboot adds the CBETxxxx prefix to the DMI version string on all Lenovo devices.

For example CBET4000 4.10-989-gc8a4e4b9c5-dirty

The coreboot DMI version string always starts with CBET.

GUID Generation

Internal device uses hardware ID values which are derived from SMBIOS.

HardwareID-3
HardwareID-4
HardwareID-5
HardwareID-6
HardwareID-10

They should match the values provided by fwupdtool hwids or the ComputerHardwareIds.exe Windows utility.

Update Behavior

The firmware is deployed to the SPI chip when the machine is in normal runtime mode, but it is only used when the device is rebooted.

Vendor ID Security

The vendor ID is set from the BIOS vendor, for example DMI:Google

Quirk Use

This plugin uses the following plugin-specific quirks:

FlashromProgrammer

Used to specify the libflashrom programmer to be used.

Since: 1.5.9

External Interface Access

This plugin requires access to all interfaces that libflashrom has been compiled for. This typically is /sys/bus/spi but there may be other interfaces as well.
