    Phoronix: Linux 4.17 Kernel Patch Brings -march=native Support

    A Gentoo user has revised his kernel patch allowing the mainline Linux kernel to be built with the GCC "-march=native" compiler optimizations for targeting the kernel build against your particular CPU...

      AFAIK, the work here has been in place on Gentoo already; it's just that the Gentoo user made a patch available upstream to make it more generally available.
      As for Linux 4.17 kernel, you should look for other items in the changelog, IMO.
      Either way, nice to see some positive news this week, with respect to OpenSource.

      Welp: based on the info shown, it's actually relevant and exciting to Gentoo users as well, after all

      The options in kernel menu config --> Processor Type and Features --> Processor Family now have an expanded list of CPUs.

            This is interesting! So what is the catch since this it not known more than it is? I mean, Gentoo users have been all about performance since the conception of it. Got to be something making the graysky patchset not the go-to-
            compiler-optimization-flag?

              How does this compare to the graysky patches?

                  From what I understand, this is just the graysky patch set going into upstream, so other distros can use it without sourcing the patch set from somewhere else.

                    Is it really going upstream? I would love it to, but I don't think it's happening.
