fwupd is a daemon that provides a safe, reliable way of applying firmware updates on Linux. Vendors can upload device firmware images to the Linux Vendor Firmware Service (LVFS) web portal. These firmware images are in turn distributed to devices running the firmware update daemon.

fwupd is colloquially referred to as Linux Vendor Firmware Service (LVFS), which is the name of the web portal used by vendors to upload device firmware.



root #emerge --ask sys-apps/fwupd

The above list of USE flag is not comprehensive. Use equery (part of the app-portage/gentoolkit package) for a full list:

user $equery uses sys-apps/fwupd




Start fwupd:

root #rc-service fwupd start

Start fwupd at boot:

root #rc-update add fwupd default


fwupd.service is launched through systemd via D-Bus automatically whenever it is needed.
