    Exactly...
    It would have been nice to have these AMD contributions in the 4.14 kernel already. It could have gone a long way in deduplication of efforts.
    Distribution maintainers now have two options:
    1. wait out 4.15 so they can offer better support for modern hardware, if they do this...
      • they will either have to update the kernel version sometime, which can be a source of instability. Dealing with which will waste resources.
      • or they will have to backport at least the security patches for their version of the 4.15 kernel. This backporting will inevitably waste resources.
    2. use 4.14 LTS for the sake of stability. In this case they will have to backport hardware enablement patches from day 0, since the kernel does not support all notable hardware pieces available at it's launch. This backporting will also inevitably waste resources.

    I know it's not the open source way, but some coordination would have been nice among different stakeholders and projects. Yes, even altering the kernel releases... say make 4.15 the LTS release.

      It would be nice if the LTS-versions would be more balanced and also suitable for Desktops (and Servers).
      But as most Linux business people gave up the desktop instead of fighting the problematic business tactics still around that is not to be expected - and even Linux Foundation shows mistrust in their own child:

      Maybe I am wrong, but Linux LTS stands only for Android-base today - not even server people would have chosen the use of 4.14 feature-wise over 4.15 - and I am pretty sure the experts are well aware of that.
      And those `must haves' are not AMD-only - even if those new support is essential - but also for Intel. So for x86 waiting for 4.15 at least would have been appropriate.
      But this is the game for several LTSs back ... no one was suited for the Desktop. But I think it never was so extreme than this round ... 4.14 would not be usable today for a recent x86 desktop or server ... and not because features haven been pushed early but those features had been delayed for much too long ... for a reason, maybe ... but not in the interest of users of current HW.
      These delays are understandable as Linux is not a first class citizen in the OS domain ... Linux desktop domination ... it was nearer in the 1990ies than today.
      Latest News are more shocking than encouraging ... and even Hurd is used more often than Linux on Intel:

      The only positive thing - Linux will survive as free software - no chance for a proprietary supercomputing OS ...
      All other domains ... we will see - or not ...

        But it is always necessary to install and run lm_sensors? I have a ryzen 1600 and MSI Tomawahk b350, does anyone know what I have to do to see the cpu temp and fan?
