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=5.11 _srcname=linux-${_major} _lqxpatchname=liquorix-package _lqxpatchrel=23 _lqxpatchver=${_lqxpatchname}-${_major}-${_lqxpatchrel} pkgbase=linux-lqx pkgver=5.11.10.lqx3 pkgrel=1 pkgdesc='Linux Liquorix' url='https://liquorix.net/' arch=(x86_64) license=(GPL2) makedepends=(bc kmod libelf cpio python pahole) if [ -n "$_htmldocs_enable" ]; then makedepends+=(xmlto python-sphinx python-sphinx_rtd_theme graphviz imagemagick) fi options=('!strip') #_lucjanpath="https://raw.githubusercontent.com/sirlucjan/kernel-patches/master/${_major}" _lucjanpath="https://gitlab.com/sirlucjan/kernel-patches/raw/master/${_major}" source=("https://cdn.kernel.org/pub/linux/kernel/v5.x/${_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") validpgpkeys=( 'ABAF11C65A2970B130ABE3C479BE3E4300411886' # Linus Torvalds '647F28654894E3BD457199BE38DBBDC86092693E' # Greg Kroah-Hartman ) sha512sums=('a567ec133018bb5ec00c60281479b466c26e02137a93a9c690e83997947df02b6fd94e76e8df748f6d70ceb58a19bacc3b1467de10b7a1fad2763db32b3f1330' 'SKIP' '6cf67239d71d1836b3271e302ba4ada3cd7adf8d9e9eac5a7a54694360a27e4548971d1325d20472317cffba618be40e8cfa07cd98f8f7ef5e0b732cfc9b90b3') 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")" echo "Patching sources with ${_patchpath#*/}" patch -Np1 -i "$_patchfolder/$_patchpath" ### Setting version echo "Setting version..." scripts/setlocalversion --save-scmversion echo "-$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 echo "Applying patch $src..." patch -Np1 < "../$src" done ### Setting config echo "Setting config..." cat ${srcdir}/${_lqxpatchver}/linux-liquorix/debian/config/kernelarch-x86/config-arch-64 >./.config make olddefconfig ### Prepared version make -s kernelrelease > version echo "Prepared $pkgbase version $( ./.config else warning "Your kernel was not compiled with IKCONFIG_PROC!" warning "You cannot read the current config!" warning "Aborting!" exit fi fi ### Disable MUQSS if [ -n "$_muqss_disable" ]; then echo "Disabling MUQSS..." scripts/config --disable CONFIG_SCHED_MUQSS scripts/config --disable CONFIG_RQ_NONE scripts/config --disable CONFIG_RQ_SMT scripts/config --disable CONFIG_RQ_MC scripts/config --disable CONFIG_RQ_MC_LLC scripts/config --disable CONFIG_RQ_SMP scripts/config --disable CONFIG_RQ_ALL scripts/config --undefine CONFIG_SHARERQ fi ### Optionally disable NUMA for 64-bit kernels only # (x86 kernels do not support NUMA) if [ -n "$_NUMAdisable" ]; then echo "Disabling NUMA from kernel config..." scripts/config --disable CONFIG_NUMA fi ### Optionally load needed modules for the make localmodconfig # See https://aur.archlinux.org/packages/modprobed-db if [ -n "$_localmodcfg" ]; then if [ -f $HOME/.config/modprobed.db ]; then echo "Running Steven Rostedt's make localmodconfig now" make LSMOD=$HOME/.config/modprobed.db localmodconfig else echo "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 $_srcname make all if [ -n "$_htmldocs_enable" ]; then make htmldocs fi } _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') provides=(VIRTUALBOX-GUEST-MODULES WIREGUARD-MODULE) cd $_srcname local kernver="$(
