Module hardware 

The hardware and firmware center: read-only facts about the machine’s firmware (through fwupd), disks, temperature sensors, batteries and PCI and USB devices, from /sys and tools that answer without root. A SMART check, which needs root, and a firmware update are plans of their own, each run only after it is confirmed.

Structs

Firmware

What fwupd knows.

FirmwareDevice

FirmwareUpdate

Hardware

Everything the center shows.

Sensor

Functions

gather

Read the machine; fwupd answers from the metadata it already has.

plan_firmware

A plan that updates one device’s firmware through fwupd. High risk: a failed firmware update can leave the device unusable.

plan_smart

A plan that reads a disk’s SMART health and attributes. It only reads, but needs root to reach the disk.

size

Bytes as GB or TB, as disks are sold.

valid_device_id

fwupd’s device ids are 40 hexadecimal digits.

valid_disk

A block device name a SMART check may name.
