    Phoronix: Clear Linux Preparing New Kernel Options

    Intel's Clear Linux platform is preparing some new alternative kernel options and they are quite interesting from a testing/benchmarking perspective...

    So, it will work on Ryzen, but not to its potential.
    They removed: AMD Microcode, AMD Numa support(will affect the performance of Threadripper and EPYC), AMD encryption, AMD IOMMU, etc...
    CONFIG_AMD_NUMA is for older Opteron type CPUs, though I don't see the point in disabling the other options other than what would be considered a "dick move" in bird culture.

    "favor their competitor's processors" - those options are enabled by default in a basic config(all distros except Clear Linux have these enabled) AND this DOES NOT affect Intel processors in any way, so it does not "favor" other processors, it just enables proper support that is available in ALL distros except Clear Linux where they explicitly kneecap AMD.

    It was fun while it lasted! Maybe someone will come along and create a bundle called native-kernel-amd and submit it for inclusion.

    So install Clear Linux as usual. Execute swupd bundle-add native-kernel-amd and it applies the needed patches and reboots.

    Yes, Intel doesn't have to approve it or support it, but to me it would be no different than installing an NVidia or Radeon specific driver.

    Off the top of my head, I don't. If you have some decent bash-fu it shouldn't be too difficult to go down the PKGBUILD, apply the patches manually, and compile it.

    Hopefully someone else will know a decent way to convert a PKGBUILD over to a Debian source package.

    One could argue that AMD might do well to be a bit cheeky and release a Clear-Linux derived spin that just changes the compiler options to favour AMD Ryzen-based CPUs...

    I'd love to see some ryzen benchmarks with this kernel testing. Very intriguing.

    An FYI for the Arch and Manjaro users, you can find these patches and more included in Tk-Glitch's kernels.

    Considering that clear targets a quite narrow set of hardware, I wouldn't expect anyone to bother with mainlining these patches.
