    Phoronix: Apple Silicon PCIe Driver Queued For Linux 5.16

    Queued this week into the Linux PCI subsystem's "next" branch is the Apple PCIe driver needed to enable PCI Express support for Apple SoCs such as the M1...

    I'm so glad that Apple still uses PCIe (at least), because at this level of closed-ness Apple may as well have created its own bus and protocol...

      Hopefully they're not reading comments here, otherwise we can easily guess what's going to be in their pipeline for the next iteration.

        Not completely; NVMe on the new Mac M1 hardware "breaks the spec in multiple ways", see https://asahilinux.org/2021/10/progr...eptember-2021/ for more details.

          Man, I can't wait to try the M1X. Yes, I know people don't think we should be rewarding Apple for this. You don't have to. They make Apple hardware to run Apple software. As a company, it makes sense for them. For the Linux/open-source community, not so much. But these MBP's have all the good stuff the old ones had (shout out to my 2010 MBP that's still running strong running GNU/Linux).

          I was originally was expecting to just run macOS on that thing, but to be able to run Linux will be a straight up joy.

          I buy Apple products for their hardware; the software is a bonus. (a big bonus).

            Half of me wants to buy one of those, smack a Linux in it and see how it goes, and how it would function as a daily driver for me.

            The other half doesn't want to throw money at Apple.

            It's great to see reverse engineering M1 progress at a good pace! We saw the day Microsoft entering open aource world, maybe we'll get to live the day when Apple pushes drivers upstream...

              Yeah but the GPU though: https://rosenzweig.io/blog/asahi-gpu-part-4.html
              glxgears?

                The GPU will come in time. It took a couple of years to get panfrost to where it is now. This time should hopefully be faster since it's not the first driver she's ever written.

                  Fuckit. throw money at apple. You're buying it because A) they bothered to make it fast and B) it's open enough to run linux.

                  You're providing incentives for exactly what you want them to do. Next one isn't open? you won't be buying it anyway.

                    That's a load of crap.
