Replace, 7:35 pm ET: Intel informed Ars Technica that it’s potential for each Intel and AMD-based platforms to replace Arc GPU firmware, and that Intel’s Administration Engine wasn’t really required for firmware updates.
“Intel Arc merchandise don’t require the host CSME to replace Arc firmware,” an Intel spokesperson informed Ars. “Firmware updates will work on each AMD and Intel platforms. Arc merchandise have their very own Graphics Safety Management for firmware updates and leverage current Intel expertise just like the HECI interface protocol to implement the firmware replace move.”
A follow-up from Richard Hughes, the developer who initially found the limitation, mentioned that one other person had informed him that an “HECI-using GSC system exhibits up in Home windows” when an Arc GPU is put in, which ought to permit updates on x86 units. We confirmed this ourselves on a Home windows PC with an Arc GPU put in and noticed Intel’s GSC firmware interface listed within the system supervisor, which must work the identical approach on each Intel and AMD platforms because it’s part of the GPU itself. (How and whether or not it would work in x86 Linux is one thing we will not affirm at this level.)
