    Phoronix: Intel's Linux Driver To Load HuC Firmware By Default For Icelake+

    For several generations now of Intel graphics there have been the GuC/HuC firmware binaries while beginning with Icelake "Gen 11" graphics those binary blobs will be loaded by default...

    Is there any disadvantage to using HuC, on devices that properly support it? In other words, do I lose anything by using HuC instead of GuC?

      @coder: GuC and HuC are not interchangeable. They serve different purposes.

        Thanks for the reply.

        I'm still trying to get my head around this. Does this mean I need to load different firmware blobs based on what I'm doing? How would this affect the ability to use Intel Media SDK and do OpenGL-based 3D rendering, at the same time?

          No. GuC and HuC are not exclusive with regards to each other and basic GPU functionality, except if you hit a bug in either GuC or HuC affecting one of the basic 3D rendering paths.
