The Linux Vendor Firmware Service is a secure portal which allows hardware vendors to upload firmware updates. This site is used by all major Linux distributions to provide metadata for clients such as fwupdmgr and GNOME Software. There is no charge to vendors for the hosting or distribution of content.
The LVFS only redistributes vendor-provided firmware, and also relies on the vendor writing release notes that accurately describe the firmware update. If your hardware vendor is not already using the LVFS you should write to them and ask them where to get the new firmware from.
Hardware vendors upload redistributable firmware to the LVFS site
packaged up in an industry-standard
.cab archive along
with a Linux-specific metadata file.
The fwupd daemon allows session software to update device firmware on the local machine. Designed for desktops, it is also usable on phones, tablets and on servers.
The LVFS and fwupd daemon are Open Source projects with contributions from dozens of people from many different companies. Plugins allow many different update protocols to be supported.
