    Hi, I noticed that in the kernel config,

    # CONFIG_NFSD is not set

    Could you please provide a patch so that it can be enabled? trying to use sudo apt-get install nsf-kernel-server

    Also, would it be possible to provide a tutorial on how to create kernel patches to enable some of these configs?

    Thanks!

    hello,

    I am trying to launch a kubernetes cluster on the tinker board 2s. however, i am met with these errors during the preflight check list. 

    [init] Using Kubernetes version: v1.22.4

[preflight] The system verification failed. Printing the output from the verification:

    It seems to be missing these items:

    CONFIG_AUFS_FS: not set - Required for aufs.
    CONFIG_CGROUP_HUGETLB: not set - Required for hugetlb cgroup.
    CGROUPS_CPU: missing
    CGROUPS_CPUSET: missing
    CGROUPS_HUGETLB: missing

    from my google search, it seems to be related to kernel. Could you please help?

    Hello,

    After successfully enabling apparmor, sudo apt-get install snapd also proved to be successful.

    However, when I carry on with sudo snap install core (or any other package), i get met with the below error:

    How should this be fixed?

    Thanks!

    Hi @tooz,

    can i please clarify with you. I am trying to rebuild the stable kernel release from https://www.kernel.org/ which is currently (5.15.5).

    The steps that I take are as follows:

    1. download linux-5.15.5.tar
    2. untar (1)
    3. cd linux-5.15.5
    4. cp arch/arm64/configs/config .config
    5. make menuconfig (optional if there are stuffs in .config that you want to amend) -> save it in .config file
    6. make -j24 bindeb-pkg
    ----- currently it is still going through no6 -----

    but after that is done, i should have an iso file that i can then do a sudo dpkg -i linux-image.deb followed by a reboot.

    Is this correct?

    I tried the 3 steps you listed, but i'm not sure at which stage should that be done instead?

    Hi,

    i am referring to the instructions here: https://gist.github.com/TinkerTeam/6286550ce70d34f6b3d483cd803da786#gistcomment-3563189 on how to compile my own kernel for tinker board 2s. 

    However, in the guide above, it listed that that it is targeting:  

    # Fetch Tinkerboard kernel config
curl -L https://raw.githubusercontent.com/TinkerBoard/debian_kernel/develop/arch/arm/configs/miniarm-rk3288_defconfig -o arch/arm/configs/miniarm-rk3288_defconfig

      But with tinker board 2s, it is a RK3399 64 bit chip. Where should I be looking at to obtain the correct defconfig?

    Thanks,

    Jake

    I am looking to enable apparmor in my tinker board 2s, and according to the documentation, i should include these lines into the kernel boot. 

    apparmor=1
security=apparmor
lsm=lockdown,yama,apparmor

    Would like to check where do i need to go to update the kernel parameters? I have tried loading it in /boot/cmdline.txt and separately in /boot/config.txt, sudo reboot the tinker board, but systemctl status apparmor still shows apparmor failing to start with: Condition check resulted in Load AppArmor profiles being skipped.

    how should i go about with this please?
