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

Building 6.1 series with same variables I was using for 6.0 series, which are

_microarchitecture=14 _config=config_x86-64-v3 _compress_modules=y

But I cannot boot it, it looks like this:

https://ibb.co/jv55VMZ

My CPU is Ryzen 9 3950x, by the way.

@hydrocryo01 ok. No ETA. I try to push the updates ASAP when upstream is done.

@figue Later I found it was due to missing kernel modules. Some additional kernel modules were loaded after I switched to a pre-compiled xanmod kernel. Not sure why the same modules weren't loaded on the stock kernel. Plus, is there an ETA for kernel 6.1.6?

@hydrocryo01 what are the parameters used to compile? If you want to see if the error is located in your config or another thing, you can try installing the binary xanmod packages:

https://aur.archlinux.org/packages?O=0&SeB=nd&K=linux-xanmod-linux-bin&outdated=&SB=p&SO=d&PP=50&submit=Go

If it boots, then it's something related to your config.

Are there some additional kernel parameters required for this kernel? I booted a unified kernel image based on linux-xanmod and found it failed to mount /efi (my ESP). I'm not sure what the problem is since vfat kernel modules is compiled. My /etc/kernel/cmdline: rw quiet splash root=LABEL=LROOT rootfstype=ext4

My /etc/fstab: ``

See fstab(5) for details.

@Riedler flex is part of base-devel, you should have all packages of that group installed to use makepkg :)

could you please add flex to the build dependencies? My build just failed because I cleaned up some unused dependencies from my installation.

@Wrexes oh. Sorry about your time lost. But the package should create all mkinitcpios, yeah?? Well, I'm happy this package works for you.

Hello~ I can totally understand why you would not set a replaces for a kernel in such a case. That said, I've made the change to regular Xanmod and (after having to DL an Archiso because I'm a dummy and forgot to make the initcpios...) I'm back on. Thanks again for your fast reply, and also for your work maintaining the package !
