    Phoronix: Linux Fixing A Major Performance Issue For Intel Hybrid Systems With Buggy Firmware

    Sent in as the sole patch for this week's Linux power management subsystem updates is an important fix for Intel Core hybrid systems with buggy firmware. The Intel P-State driver fix can address as much as a 50% performance hit seen with existing Linux kernel versions on affected Intel hybrid platforms...

    This is one advantage Apple has as a company that is extremely vertically integrated. They control the hardware. They control the OS. They control the EFI and most (all?) of the more granular component firmware. In the Windows and Linux world, everyone in the supply chain has a chance to screw something up.

      How can I see if my system is hitting the bug?

      Well, admittedly, the problem of my LG Gram is the lack of cooling, so going to higher frequencies would be even worst XD

        Well, I do have a Gigabyte 15 BSF, and a MinisForum NPB5, both running a Core i5 13500H.

        Is there a way to determine if ACPI CPPC v2 is/not reported?

        The Intel P-State driver fix can address as much as a 50% performance ​​​hit...
        Is this on very specific workloads, or is this in general?

        *Update*
        The report created by the Kubuntu Focus developer linked to GitHub and the Manjaro Forums. Both feature more information on this topic.

        One fix mentioned is disabling the E-cores, (Fortunately) my Laptop and the MinisForum BIOS have this option - Though battery life will naturally suffer on the Laptop.

            And they're still the slowest when comes to OS.

              in this kind of cases Linux should output in the log: WARNING: loading workaround for buggy system firmware. Please contact the hardware manufacturer.

              if they get enough work answering all those customers it might end up cheaper to just release a trivial fix.

                Perhaps…but the better option is for Intel to outright buy AMI or Phoenix and then force one of them to produce a vertically integrated BIOS….errr…UEFI just like Apple does. This doesn’t mean that the now Intel owned AMI or Phoenix couldn’t continue to make platform specific BIOS’s for other clients including AMD. But enough of this bullshit in the fragmented x86 world. Even Google for God’s sake is cracking down on their fragmented environment by forcing device makers to take Android images that have core components that are upgraded by Google regardless of the device makers timeline of support for OS and OS components which sometimes is as short as 6 months until EOL….
                ( looking at YOU Lenovo. )

                  Citation please. Also….what’s worse? A slow fix that actually fixes? Or a fast fix that must be even more quickly fixed?

                    slow in performance, everyone understand that
