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= ### Do not edit below this line unless you know what you're doing pkgbase=linux-rt-bfq # pkgname=('linux-rt-bfq' 'linux-rt-bfq-headers' 'linux-rt-bfq-docs') _major=4.19 _minor=31 _rtver=18 _rtpatchver=rt${_rtver} pkgver=${_major}.${_minor}.${_rtpatchver} _pkgver=${_major}.${_minor} _srcname=linux-${_pkgver} pkgrel=2 arch=('x86_64') url="https://github.com/Algodev-github/bfq-mq/" license=('GPL2') options=('!strip') makedepends=('kmod' 'inetutils' 'bc' 'libelf' 'python-sphinx' 'graphviz') _bfq_sq_mq_path="bfq-sq-mq" _bfq_sq_mq_ver='v10r1' _bfq_sq_mq_rel='2K190313-rc1' _bfq_sq_mq_patch="${_major}-bfq-sq-mq-${_bfq_sq_mq_ver}-${_bfq_sq_mq_rel}.patch" #_lucjanpath="https://raw.githubusercontent.com/sirlucjan/kernel-patches/master/${_major}" _lucjanpath="https://gitlab.com/sirlucjan/kernel-patches/raw/master/${_major}" _gcc_path="https://raw.githubusercontent.com/graysky2/kernel_gcc_patch/master" _gcc_patch="enable_additional_cpu_optimizations_for_gcc_v8.1+_kernel_v4.13+.patch" source=("https://www.kernel.org/pub/linux/kernel/v4.x/${_srcname}.tar.xz" "https://www.kernel.org/pub/linux/kernel/v4.x/${_srcname}.tar.sign" "http://www.kernel.org/pub/linux/kernel/projects/rt/${_major}/patch-${_pkgver}-${_rtpatchver}.patch.xz" "http://www.kernel.org/pub/linux/kernel/projects/rt/${_major}/patch-${_pkgver}-${_rtpatchver}.patch.sign" "${_lucjanpath}/${_bfq_sq_mq_path}/${_bfq_sq_mq_patch}" "${_lucjanpath}/0100-Check-presence-on-tree-of-every-entity-after-every-a.patch" "${_gcc_path}/${_gcc_patch}" "${_lucjanpath}/arch-patches/0001-add-sysctl-to-disallow-unprivileged-CLONE_NEWUSER-by.patch" "${_lucjanpath}/aur-patches/fix-race-in-PRT-wait-for-completion-simple-wait-code_Nvidia-RT-160319.patch" # the main kernel config files 'config' # pacman hook for depmod '60-linux.hook' # pacman hook for initramfs regeneration '90-linux.hook' # pacman hook for remove initramfs '99-linux.hook' # standard config files for mkinitcpio ramdisk 'linux.preset') _kernelname=${pkgbase#linux} : ${_kernelname:=-rt-bfq} prepare() { cd ${_srcname} ### Add rt patch msg2 "Add rt patch" patch -Np1 -i ../patch-${_pkgver}-${_rtpatchver}.patch ### Setting version msg2 "Setting version..." scripts/setlocalversion --save-scmversion echo "-$pkgrel" > localversion.10-pkgrel echo "$_kernelname" > localversion.20-pkgname ### Patching sources local src for src in "${source[@]}"; do src="${src%%::*}" src="${src##*/}" [[ $src = *.patch ]] || continue msg2 "Applying patch $src..." patch -Np1 < "../$src" done ### Setting config msg2 "Setting config..." cp ../config .config make olddefconfig ### Prepared version make -s kernelrelease > ../version msg2 "Prepared %s version %s" "$pkgbase" "$(<../version)" ### Optionally use running kernel's config # code originally by nous; http://aur.archlinux.org/packages.php?ID=40191 if [ -n "$_use_current" ]; then if [[ -s /proc/config.gz ]]; then msg2 "Extracting config from /proc/config.gz..." # modprobe configs zcat /proc/config.gz > ./.config else warning "You kernel was not compiled with IKCONFIG_PROC!" warning "You cannot read the current config!" warning "Aborting!" exit fi fi ### Optionally set tickrate to 1000 if [ -n "$_1k_HZ_ticks" ]; then msg2 "Setting tick rate to 1k..." sed -i -e 's/^CONFIG_HZ_300=y/# CONFIG_HZ_300 is not set/' \ -i -e 's/^# CONFIG_HZ_1000 is not set/CONFIG_HZ_1000=y/' \ -i -e 's/^CONFIG_HZ=300/CONFIG_HZ=1000/' ./.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 msg2 "If you have modprobed-db installed, running it in recall mode now" if [ -e /usr/bin/modprobed-db ]; then [[ -x /usr/bin/sudo ]] || { echo "Cannot call modprobe with sudo.
