Useful when the package gets updated and you already went # through the trouble of customizing your config options. NOT recommended when # a new kernel is released, but again, convenient for package bumps. _use_current= ### Disable MUQSS _muqss_disable= ### Enable htmldocs (increases compile time) _htmldocs_enable= ### Do not edit below this line unless you know what you're doing # pkgname=('linux-lqx' 'linux-lqx-headers' 'linux-lqx-docs') _major=5.6 _srcname=linux-${_major} _lqxpatchname=liquorix-package _lqxpatchrel=8 _lqxpatchver=${_lqxpatchname}-${_major}-${_lqxpatchrel} pkgbase=linux-lqx pkgver=5.6.12_1 pkgrel=1 pkgdesc='Liquorix Kernel' arch=('x86_64') url="http://liquorix.net/" license=('GPL2') options=('!strip') makedepends=('kmod' 'inetutils' 'bc' 'libelf' 'cpio') if [ -n "$_htmldocs_enable" ]; then makedepends+=('python-sphinx' 'python-sphinx_rtd_theme' 'graphviz' 'imagemagick') fi source=("https://cdn.kernel.org/pub/linux/kernel/v5.x/${_srcname}.tar.xz" "https://cdn.kernel.org/pub/linux/kernel/v5.x/${_srcname}.tar.sign" "https://github.com/damentz/${_lqxpatchname}/archive/${_major}-${_lqxpatchrel}.tar.gz") export KBUILD_BUILD_HOST=archlinux export KBUILD_BUILD_USER=$pkgbase export KBUILD_BUILD_TIMESTAMP="$(date -Ru${SOURCE_DATE_EPOCH:+d @$SOURCE_DATE_EPOCH})" prepare() { cd $_srcname ### Set package version variables _abiname="$(cat ${srcdir}/${_lqxpatchver}/linux-liquorix/debian/config/defines | grep 'abiname:' | sed -r 's/abiname:\s*//')" _minor="$(echo "$_abiname" | cut -f1 -d .)" _patchrel="$(echo "$_abiname" | cut -f2 -d .)" ### Add Liquorix patches local _patchrx='^zen/v\d+\.\d+\.\d+-lqx\d+.patch$' local _patchfolder="${srcdir}/${_lqxpatchver}/linux-liquorix/debian/patches" local _patchpath="$(grep -P "$_patchrx" "$_patchfolder/series")" msg2 "Patching sources with ${_patchpath#*/}" patch -Np1 -i "$_patchfolder/$_patchpath" ### Setting version msg2 "Setting version..." scripts/setlocalversion --save-scmversion echo "-$pkgrel" > localversion.10-pkgrel echo "${pkgbase#linux}" > localversion.20-pkgname ### Patching sources local src for src in "${source[@]}"; do src="${src%%::*}" src="${src##*/}" [[ $src = *.patch ]] || continue msg2 "Applying patch $src..." patch -Np1 < "../$src" done ### Setting config msg2 "Setting config..." cat ${srcdir}/${_lqxpatchver}/linux-liquorix/debian/config/kernelarch-x86/config-arch-64 >./.config make olddefconfig ### Prepared version make -s kernelrelease > version msg2 "Prepared %s version %s" "$pkgbase" "$( ./.config else warning "Your kernel was not compiled with IKCONFIG_PROC!" warning "You cannot read the current config!" warning "Aborting!" exit fi fi ### Disable MUQSS if [ -n "$_muqss_disable" ]; then msg2 "Disabling MUQSS..." sed -i -e s'/^CONFIG_SCHED_MUQSS=y/# CONFIG_SCHED_MUQSS is not set/' ./.config fi ### Optionally disable NUMA for 64-bit kernels only # (x86 kernels do not support NUMA) if [ -n "$_NUMAdisable" ]; then msg2 "Disabling NUMA from kernel config..." sed -i -e 's/CONFIG_NUMA=y/# CONFIG_NUMA is not set/' \ -i -e '/CONFIG_AMD_NUMA=y/d' \ -i -e '/CONFIG_X86_64_ACPI_NUMA=y/d' \ -i -e '/CONFIG_NODES_SPAN_OTHER_NODES=y/d' \ -i -e '/# CONFIG_NUMA_EMU is not set/d' \ -i -e '/CONFIG_NODES_SHIFT=6/d' \ -i -e '/CONFIG_NEED_MULTIPLE_NODES=y/d' \ -i -e '/# CONFIG_MOVABLE_NODE is not set/d' \ -i -e '/CONFIG_USE_PERCPU_NUMA_NODE_ID=y/d' \ -i -e '/CONFIG_ACPI_NUMA=y/d' ./.config fi ### Optionally load needed modules for the make localmodconfig # See https://aur.archlinux.org/packages/modprobed-db if [ -n "$_localmodcfg" ]; then if [ -f $HOME/.config/modprobed.db ]; then msg2 "Running Steven Rostedt's make localmodconfig now" make LSMOD=$HOME/.config/modprobed.db localmodconfig else msg2 "No modprobed.db data found" exit fi fi ### Running make nconfig [[ -z "$_makenconfig" ]] || make nconfig ### Running make menuconfig [[ -z "$_makemenuconfig" ]] || make menuconfig ### Running make xconfig [[ -z "$_makexconfig" ]] || make xconfig ### Running make gconfig [[ -z "$_makegconfig" ]] || make gconfig ### Save configuration for later reuse cat .config > "${startdir}/config.last" } build() { cd $_srcname local params=(bzImage modules) if [ -n "$_htmldocs_enable" ]; then params+=(htmldocs) fi make ${params[*]} } _package() { pkgdesc="The $pkgdesc kernel and modules" depends=('coreutils' 'kmod' 'initramfs') optdepends=('crda: to set the correct wireless channels of your country' 'linux-firmware: firmware images needed for some devices' 'sof-firmware: firmware images needed for Sound Open Firmware capable devices' 'modprobed-db: Keeps track of EVERY kernel module that has ever been probed - useful for those of us who make localmodconfig') cd $_srcname local kernver="$(
