  • Debian Bullseye 64-bit for the Khadas VIM4

    From Larry Dighera@21:1/5 to All on Tue May 17 01:30:01 2022
    Is there hope of seeing a port of Debian Bullseye 64-bit for the Khadas VIM4 any time soon?

    https://www.khadas.com/vim4
    The VIM4 SBC is the latest addition to our popular Khadas VIM series. It
    has a powerful Amlogic A311D2 SoC, featuring a 2.2GHz quad core ARM
    Cortex-A73, and 2.0GHz quad core Cortex-A53 CPU. HDR10, HDR10+, HLG and
    PRIME HDR video processing are supported, and TrustZone based security
    is used for DRM video streaming.

    The Khadas VIM4 and the A311D2 SoC both don't appear to be supported by
    Linux mainline yet, I don't see any reference to either in linux.git,
    but there are references to the previous generation, Khadas VIM3, so
    it is possible that someone will work on this.

    Once support for the device is upstream, the support will enter Debian
    unstable after the next Linux kernel release, then potentially some
    build config changes will be needed to enable new drivers, then the
    package will migrate to Debian testing, then Debian backports and then
    you will be able to use the backport on Debian stable. Generally
    support for newer SoCs does not get backported to older Linux kernel
    versions such as the one in Debian bullseye, but a newer Linux kernel
    version is added to bullseye-backports. This can take a long time.

    Until then you can use whatever Linux kernel build supports the Khadas
    VIM4 such as one from the vendor BSP or from Armbian, on plain Debian.

    Depending on your use-cases you may need to also get updated packages
    for userspace drivers (such as GPU drivers) or firmware.

    Perhaps this information will assist the porting team if/when that occurs.

    I suggest that you contact Khadas and Amlogic about their plans for
    mainlining Linux support for the device. Alternatively, if you have a
    budget for getting the work done, the BayLibre Linux consulting company
    seem to be the main contributor to Amlogic/Khadas support in Linux.
    Its also possible that they are already working on it, not sure though.
