Phoronixhas discovered a new open source Intel project for Linux version 5.17 that allows a motherboard to update firmware, such as its BIOS, without requiring a system reboot. The “PFRUT” or Platform Firmware Runtime and Telemetry drivers feature comes as part of the widely used ACPI feature set. This means that the same solution may come to Windows systems in the future.
PFRUT will basically provide convenience when we want to update the BIOS and will eliminate the need to reboot the system. This feature can be very useful, especially on servers that can impact the workforce. Servers that don’t require reboots can keep critical workloads running the entire time while updating the system BIOS.
Currently this is said to be a server space specific thing and it is unclear whether it will reach all consumers for Linux operating systems. With PFRUT, the update process is done through the operating system rather than directly in the system BIOS. There may be some hardware requirements to support the feature and nothing is finalized about it. A supported motherboard may be needed, or anything is possible with a PFRUT driver without hardware support.
It is not known exactly which platforms this function will come to. However, since it is based on the ubiquitous ACPI specifications, it is possible to be used by consumer computers.
