Intel is working to provide the Linux kernel with the ability to allow BIOS updates without a reboot.
Certain compute systems require high Service Level Agreements (SLAs) where fewer system reboot firmware updates are required for deploying firmware changes to address bug fixes, security updates, and to debug and root cause issues. Ever since BIOS updates became possible, the process required rebooting the PC.
Intel is now changing that, thanks to a new part of the ACPI specification called Platform Firmware Runtime Update and Telemetry (PFRUT). This allows for firmware updates to a PC’s BIOS or UEFI without forcing a reboot. The idea is to reduce downtime, especially for servers that should ideally remain available 100 percent of the time.
Intel’s been working on PFRUT for some time, previously under the moniker “Seamless Update.”
So, Linux kernel 5.16 is now available, and Intel aims to merge this new addition with the upcoming Linux kernel 5.17 stable release. Right now, the driver update is in the “linux-next” branch.
The upcoming pfr_update driver is set to be introduced in Linux kernel 5.17. Sources say it appears to be designed for system firmware updates in cases of critical bugs or security issues, allowing server administrators to patch their hardware without downtime. The operating system will be responsible for executing the entire update process.
PFRUT should give systems the advantage of not requiring a system restart when you update the BIOS. This feature will be very useful in server deployments where downtime can hinder business operations.
We can’t fail to mention that one of the biggest surprises to come along with PFRUT, is that it will only be available for Linux. That said, the intent of this is for servers, so it remains to be seen if this functionality will come to desktop PCs or Windows.
I love that gif. God definitely has a sense of humor.
They come out with BIOS updates how often? Every several years?
I’m just glad that I don’t have to restart after most updates or get forced updates, unannounced updates like my family does on windows 10. I update when I want and rarely have to restart when I do on Kubuntu.
Believe it or not, BIOS updates can come out a couple times per year for server-level systems.

Ah ok, and most servers are Linux.
Torvalds would appreciate the flattery but Gates is the one with the god complex.
I don't know if it started with Linus picking the penguin to be the Linux mascot but overall Linux is a far more lighthearted endeavor than anything the mind-numbed Windoze robots could come up with. The whole guh-noo, guh-nome, Kommander, Konqueror thing probably is a bit bewildering to Linux newbies but I find the kitsch and the sense of humor is part of its charm.
In addition to the fact that it's a bur under Bill's saddle that he can't make a dent in the handheld digital devices market on account of widespread loyalty to that penguin and its stepchild, the bugdroid.
This is an incredible breakthrough given the high frequency of BIOS updates we’ve experienced. < /sarcasm>
