Intel Wants to Enable UEFI Updates Without Reboots

Most persons do not essentially like rebooting, but the pace and balance of modern day methods make it a nominal chore these times. For company clients with Assistance Amount Agreements that mandate a confirmed amount of uptime, even so, each individual reboot implies a threat of not satisfying the conditions of the agreement.

Intel has a approach to deal with this situation, dubbed Intel Seamless Update. That is according to Phoronix, who spotted evidence that new patches in the Linux kernel are currently being extra to help this kind of a function. They element how Intel is introducing help close to its System Firmware Runtime Update and Telemetry motorists. There is also a latest Intel whitepaper that references an “Intel Seamless Update” engineering.

The whitepaper states:

Intel’s solution is named Intel® Seamless Update. The administration manner (MM), UEFI runtime products and services and ACPI services tackle most of the system runtime functions. Intel® processor architecture supports MM by Procedure Management Mode (SMM). Switching the MM code execution for the duration of runtime is named MM Runtime Update (MRU).

Although Intel’s document does not precisely point out this, there are many references to “runtime firmware improvements.” Phoronix casts this as a UEFI update system, but I’m not specified the update if the is truly flashed to the UEFI firmware. Intel’s whitepaper does not sketch out a particular “Write Update to Firmware” move the way Microsoft’s suggestions for distributing UEFI versions by using Windows Update do:

Intel’s recommendations do refer to an MM Driver Update purpose, but they also point out: “The code update infrastructure permits offering runtime firmware variations that are qualified for hardware and firmware point out modifications to make it possible for safety or general performance enhancements.” This could be study to indicate the UEFI enhancements are becoming loaded at runtime by using the MM alternatively than that the UEFI is actually currently being flashed without rebooting the OS.

We have a question in to Intel on this place and will update the tale if we hear back again.

Both way, nevertheless, this is a notable step forward for enterprise programs. The capacity to apply a UEFI flash (or the equivalent of a UEFI flash) without having rebooting is a great element. Intel’s Seamless Update doesn’t show up to demand specialised components, just driver and OS assistance. If the aspect is staying baked into Linux, it could appear to the Windows company as effectively and then trickle down into customer solutions at a later on date. Microsoft has put significant do the job into minimizing the number of reboots Windows customers require to make more than the previous two a long time, and not needing to reboot to update process firmware would take an additional purpose off the desk.
