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 '' 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

## 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

## 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

# 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"

# 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:
if [ -z ${_config+x} ]; then

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

# 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:
# This PKGBUILD read the database kept if it exists
# More at this wiki page --->
if [ -z ${_localmodcfg} ]; then

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

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}"
        # myconfig is a full config file. Replacing default .config
        msg2 "Using user CUSTOM config..."
        cp -f "${_myconfig}" .config

@Riedler yeah, I personally use only a reduced myconfig, so I didn't have to maintain a full config:

cat .config/linux-xanmod/myconfig      
scripts/config --enable CONFIG_IWLWIFI_DEBUG
scripts/config --module CONFIG_MMC_BLOCK
scripts/config --set-val MMC_BLOCK_MINORS 8
scripts/config --module CONFIG_SND_DMAENGINE_PCM
scripts/config --module CONFIG_SND_COMPRESS_OFFLOAD
scripts/config --module CONFIG_AC97_BUS
scripts/config --enable CONFIG_INPUT_TABLET
scripts/config --enable CONFIG_TRACING
scripts/config --enable CONFIG_KPROBE_EVENTS
scripts/config --enable CONFIG_BPF_EVENTS

@figue nothing too crazy I think. Not even sure if any of this goes through to linux-xanmod.

/etc/makepkg →

as for myconfig - yeah somewhat, see here:

I should probably stop using the myconfig, I don't have time to maintain the custom one anymore…

figue commented on 2024-04-07 12:14 (UTC)

@Riedler are you using any custom flag?

Riedler commented on 2024-04-07 10:35 (UTC)

I'm sorry I don't have time to debug this rn 😢 I just wanted to mention the error in case it's an obvious problem somewhere…

xiota commented on 2024-04-07 10:08 (UTC)

@Riedler Have you tried building in a clean chroot?

Seems to have built okay here: linux-xanmod.log

Riedler commented on 2024-04-07 10:04 (UTC)

since after 6.7.7 I haven't been able to compile this package. It says: libbpf: failed to find '.BTF' ELF section in /tmp/makepkg/linux-xanmod/src/linux-6.7/vmlinux when I try to compile 6.7.12…

figue commented on 2024-01-14 16:03 (UTC)

@xiota thank you.

  1. Will be merged in next release.

  2. Headers package doesn't need it IMHO.

xiota commented on 2024-01-14 14:41 (UTC) (edited on 2024-01-14 14:44 (UTC) by xiota)

In following code block, python should be removed because it is already in the main makedepends:

if [ "${_compiler}" = "clang" ]; then
  makedepends+=(clang llvm lld python)

Also, may be worthwhile to add following to _package-headers() because dkms modules need the compiler originally used to make the kernel, but dkms depends on gcc only.

if [ "${_compiler}" = "clang" ]; then
  depends+=(clang llvm lld)

Same apply to linux-xanmod-lts. They can wait until the next version bump.

I'm sorry, my stupidity, there wasn't enough disk space
