Adding

scripts/config --disable CONFIG_IMA_ARCH_POLICY

to myconfig does solve the "Failed to insert module 'nvidia': Key was rejected by service" problem.

Anyone who configured secure boot using sbctl and want to load dkms modules can try this solution.

This package have several variables to enable/disable features.

##
## The following variables can be customized at build time. Use env or export to change at your wish
##
##   Example: env _microarchitecture=98 use_numa=n use_tracers=n makepkg -sc
##
## Look inside 'choose-gcc-optimization.sh' to choose your microarchitecture
## Valid numbers between: 0 to 99
## Default is: 0 => generic
## Good option if your package is for one machine: 98 (Intel native) or 99 (AMD native)
if [ -z ${_microarchitecture+x} ]; then
  _microarchitecture=0
fi

## Disable NUMA since most users do not have multiple processors. Breaks CUDA/NvEnc.
## Archlinux and Xanmod enable it by default.
## Set variable "use_numa" to: n to disable (possibly increase performance)
##                             y to enable  (stock default)
if [ -z ${use_numa+x} ]; then
  use_numa=y
fi

## Since upstream disabled CONFIG_STACK_TRACER (limits debugging and analyzing of the kernel)
## you can enable them setting this option. Caution, because they have an impact in performance.
## Stock Archlinux has this enabled. 
## Set variable "use_tracers" to: n to disable (possibly increase performance, XanMod default)
##                                y to enable  (Archlinux default)
if [ -z ${use_tracers+x} ]; then
  use_tracers=n
fi

# Unique compiler supported upstream is GCC
## Choose between GCC and CLANG config (default is GCC)
## Use the environment variable "_compiler=clang"
if [ "${_compiler}" = "clang" ]; then
  _compiler_flags="CC=clang HOSTCC=clang LLVM=1 LLVM_IAS=1"
fi

# Choose between the 4 main configs for stable branch. Default x86-64-v1 which use CONFIG_GENERIC_CPU2:
# Possible values: config_x86-64-v1 (default) / config_x86-64-v2 / config_x86-64-v3 / config_x86-64-v4
# This will be overwritten by selecting any option in microarchitecture script
# Source files: https://github.com/xanmod/linux/tree/5.17/CONFIGS/xanmod/gcc
if [ -z ${_config+x} ]; then
  _config=config_x86-64-v1
fi

# Compress modules with ZSTD (to save disk space)
if [ -z ${_compress_modules+x} ]; then
  _compress_modules=n
fi

# Compile ONLY used modules to VASTLY reduce the number of modules built
# and the build time.
#
# To keep track of which modules are needed for your specific system/hardware,
# give module_db script a try: https://aur.archlinux.org/packages/modprobed-db
# This PKGBUILD read the database kept if it exists
#
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db
if [ -z ${_localmodcfg} ]; then
  _localmodcfg=n
fi

# Tweak kernel options prior to a build via nconfig
if [ -z ${_makenconfig} ]; then
  _makenconfig=n
fi

Personally I'm running now xanmod kernel compiled with this:

env _microarchitecture=98 use_tracers=n use_numa=n _localmodcfg=y _compress_modules=y makepkg -sic

Also, you can now create the file myconfig in your local repo to build this package with a custom config or use ${XDG_CONFIG_HOME}/linux-xanmod/myconfig. This file can be a full kernel config or be a script with several entries to add/remove options (you have several examples in PKGBUILD by using scripts/config):

Code involved:

  for _myconfig in "${SRCDEST}/myconfig" "${HOME}/.config/linux-xanmod/myconfig" "${XDG_CONFIG_HOME}/linux-xanmod/myconfig" ; do
    if [ -f "${_myconfig}" ] && [ "$(wc -l <"${_myconfig}")" -gt "0" ]; then
      if grep -q 'scripts/config' "${_myconfig}"; then
        # myconfig is a partial file. Executing as a script
        msg2 "Applying myconfig..."
        bash -x "${_myconfig}"
      else
        # myconfig is a full config file. Replacing default .config
        msg2 "Using user CUSTOM config..."
        cp -f "${_myconfig}" .config
      fi
      echo
      break
    fi
  done

@ahuston-0 don't worry about that... It means that a module is already included in kernel image

For anyone who's having issues with compiling the kernel due to this bug:

cp: cannot stat '(builtin)': No such file or directory

There's a potential fix in #65725 [https://bugs.archlinux.org/task/65725]. For now it looks like you can install mkinitcpio-28 from the testing repo and it should allow you to compile linux-xanmod and linux-clear at the very least (those are the ones tested so far that I'm aware of).

@romulasry zstd compression is already included to xanmod kernel. You can activate by default setting CONFIG_KERNEL_ZSTD in build time.

You can use myscript file, just create that file and add:

scripts/config --enable CONFIG_KERNEL_ZSTD
scripts/config --disable CONFIG_KERNEL_LZ4

I haven't tested, but should do the trick.

You want to make a zstd version or add it to this, here are the patches: https://sourceforge.net/projects/xanmod/files/patches/linux-5.7.y-xanmod/kernel_zstd/

@atxnor try the package nvidia-beta-all. i can confirm that that one properly work on both a gtx 960 and on the RTX 2060 KO and provides nvidia=440.82 and nvidia-beta=440.82. hope that help's.

can't build NVIDIA prop driver 440.82 with xanmod-5.7

@francois072 I have VirtualBox host on my computer, and modules build fine:

figue@pluto ~ % uname -a
Linux pluto 5.7.2-xanmod1-1-xanmod #1 SMP PREEMPT Thu, 11 Jun 2020 12:13:31 +0000 x86_64 GNU/Linux
figue@pluto ~ % lsmod | grep vbox
vboxnetflt             32768  0
vboxnetadp             28672  0
vboxdrv               503808  2 vboxnetadp,vboxnetflt

I'm using virtualbox-host-dkms package.

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please try setting it up again by executing

'/sbin/vboxconfig'

as root.

If your system has EFI Secure Boot enabled you may also need to sign the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load them. Please see your Linux system's documentation for more information.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

@figue yes it does still boot and function normal. Just thought I would inform the maintainer of the error. Also I have the virtualbox modules installed and virtualbox does function with the stock kernel but I get an error when using xanmod.

I used your recommended "env use_tracers=n use_numa=n use_pds=y use_ns=y makepkg -s" when compiling the kernel just now. I would like to let Manjaro's Pamac automatically compile the kernel as you suggested but I'm not sure how to do that. I did see your "Reference"

@francois072 does it boot even with the warning? By default, XanMod's config has some configs integrated in kernel image and not as module. mkinitcpio tries to load all modules to boot in the initrd, but it output a warning in that case.
