    Phoronix: Raspberry Pi's Raspbian Finally Moves Up To Linux 4.14 Kernel

    Raspberry Pi's official Linux distribution, Raspbian, is now ready with their Linux 4.14 kernel to replace their aging Linux 4.9-based kernel...

    Even 4.14 is a lttle old considering Spectra, Meltdown and the like.

    By the way yes i know back porting is being done but '16 isnt far away. From my perspective all of these processor bugs make the old kernels less attractive.

      Do any of those vulnerabilities affect the A53 or A9 cores? Actually, I think the A9 is effected. Yep:https://en.wikipedia.org/wiki/Spectr...bility)#Impact

        You really need to read this: https://www.raspberrypi.org/blog/why...e-or-meltdown/

        I'll be working on some benchmarks of the Linux 4.9 vs. 4.14 kernels on Raspbian with the Raspberry Pi hardware shortly.
        Sounds excellent :-) Could you please include both temperature measurements graphs and clock frequency graphs (e.g. "vcgencmd measure_clock arm")? As I wrote in another thread, the newer Raspberries are largely thermally limited and will throttle the frequency - effectively making adding a heatsink an easy performance boost

          Could one of you who has one of these please check if Raspian ships with a mtp_usb driver? It would probably live in /lib/modules/<kernel>/kernel/drivers/usb/gadget, perhaps as *f_mtp. It is used by mtp-server to export files as a mtp host device by Android. I'm wondering if Raspian can do it as well?

            Hi, I have a raspberry 2 with Raspbian from a few months ago with the 4.9 kernel.
            Can you give me an exact command to search that driver ?
            I tried a tree of /lib/modules but the output is too big to paste it here.
            This is the list of the beginning of that path:
            Code:

            So a search file by name command would be great, if you can give me one.

              I'm not seeing it on 4.14.

              Code:
              root@pi:/lib/modules# find . -iname *mtp*
              ./4.14.30-v7+/kernel/sound/drivers/snd-mtpav.ko
              ./4.14.30+/kernel/sound/drivers/snd-mtpav.ko

                I don't see anything MTP-related in there on my RPi Zero W, but I noticed this discussion on GH: https://github.com/raspberrypi/usbbo...ment-352592363

                  Thanks! Try this:

                  find /lib/modules/4.9.59-v7+/kernel/drivers -name \*mtp\*

                  ...and see what it turns up. The backslashes escaping the *'s might not be needed.
