    Phoronix: Lenovo Laptop Platform Profile Support Queued Ahead Of Linux 5.12

    Lenovo continues working on a number of contributions to the upstream kernel thanks to their work on preloading various Linux distributions on a number of different devices. In cooperation with Red Hat engineers over the past year we have seen a lot of Lenovo related improvements and the latest set to come with the Linux 5.12 cycle is ACPI platform profile support for their laptops...

    Will this be ultimately extended to their ultrabook lines? or they are already included in this
    More and more reasons to buy a Lenovo, specially if they ship with new zen3

      Some manufacturers, such as ASUS (notably bad compatibility with Linux), should be taking notes.

        I agree. After buying both a Bristol Ridge APU equipped Lenovo Ideapad laptop and an HP Pavilion Desktop also equipped with a slightly more powerful Bristol Ridge APU I saw first-hand how Lenovo had a less broken ACPI profile in BIOS as opposed to the awful shit show of ACPI errors in the HP desktop.

        Granted, by the time Bristol Ridge came out AMD had already moved away from Fusion and HSA and bet the farm on Zen and getting back the server market. So BIOS from the likes of Dell, HP and even Lenovo on shitty motherboards that had a Carrizo or Bristol Ridge made to the lowest spec was a low priority. But at least Lenovo was far less FUBAR.

        On an unrelated note, but not really, Lenovo seems to fark around their Android phones far less than anyone else with the exception of Google of course. Plus they have jumped in one year from 5th in market share in Chromebooks to displacing Acer at #2 right behind HP. Plus they are now supporting Linux right out of the box with their Thinkpad and Thinkcentre deskrops. That's all to say that it seems that Lenovo has gone full into supporting Linux in ALL it's forms, from Android, ChromeOS and Linux proper.

        Good on ya' Lenovo !!

            Educated guess: DYnamic Thermal Controller

              Possible tense/verb mismatch typo:

              As noted in that article from December, this platform profile support is allow altering the laptop hardware's operating profile characteristics around power/performance levels and in turn thermal and fan speed behavior
              Perhaps "...support is allowed to alter the..."
              GOD is REAL unless declared as an INTEGER.

                With Ultrabooks I guess your referring to the Lenovo X line of ThinkPads, like the various X1 and X13 models? Those are obviously covered by the thinkpad_acpi driver.

                  So
                  /sys/firmware/platform_profile
                  is the same as setting

                  /sys/devices/system/cpu/cpufreq
                  and
                  /sys/devices/platform/applesmc.768/fan1_output
                  or changing the bios config... so many hardware dependant ways of doing the same thing.

                    Actually was referring more to the yoga lines and the new slim 7/ slim7 pro (I think those might be ideaPads)
