# Maintainer: graysky # Contributor: Thomas Baechler ### BUILD OPTIONS # Set these variables to ANYTHING that is not null to enable them # Tweak kernel options prior to a build via nconfig _makenconfig= # NUMA is optimized for multi-socket motherboards. A single multi-core CPU can # actually run slower with NUMA enabled. Most users will want to set this option # to enabled ... in other words, do not use NUMA on a single CPU system. # # See, https://bugs.archlinux.org/task/31187 _NUMAdisable=y # Compile ONLY probed modules # As of mainline 2.6.32, running with this option will only build the modules # that you currently have probed in your system VASTLY reducing the number of # modules built and the build time to do it. # # WARNING - ALL modules must be probed BEFORE you begin making the pkg! # # 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 will call it directly to probe all the modules you have logged! # # More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db _localmodcfg= # Use the current kernel's .config file # Enabling this option will use the .config of the RUNNING kernel rather than # the ARCH defaults. 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 no edit below this line unless you know what you're doing pkgbase=linux-ck _srcname=linux-4.13 pkgver=4.13.9 pkgrel=1 _ckpatchversion=1 arch=('i686' 'x86_64') url="https://wiki.archlinux.org/index.php/Linux-ck" license=('GPL2') makedepends=('kmod' 'inetutils' 'bc' 'libelf') options=('!strip') _ckpatchname="patch-4.13-ck${_ckpatchversion}" _gcc_patch='enable_additional_cpu_optimizations_for_gcc_v4.9+_kernel_v4.13+.patch' source=("http://www.kernel.org/pub/linux/kernel/v4.x/${_srcname}.tar.xz" "https://www.kernel.org/pub/linux/kernel/v4.x/${_srcname}.tar.sign" "https://www.kernel.org/pub/linux/kernel/v4.x/patch-${pkgver}.xz" "https://www.kernel.org/pub/linux/kernel/v4.x/patch-${pkgver}.sign" "http://ck.kolivas.org/patches/4.0/4.13/4.13-ck${_ckpatchversion}/${_ckpatchname}.xz" "$_gcc_patch::https://raw.githubusercontent.com/graysky2/kernel_gcc_patch/master/enable_additional_cpu_optimizations_for_gcc_v4.9%2B_kernel_v4.13%2B.patch" 'unfuck_bfq.patch' # the main kernel config files 'config.i686' 'config.x86_64' # pacman hook for initramfs regeneration '90-linux.hook' # standard config files for mkinitcpio ramdisk 'linux.preset') sha256sums=('2db3d6066c3ad93eb25b973a3d2951e022a7e975ee2fa7cbe5bddf84d9a49a2c' 'SKIP' '22156e82467c7911d226a0a887eba19103434efc104439a3b426a3fa551fb8f2' 'SKIP' 'a44bf7af8cec88aeb1159ecb4a0395bc214eb98fe6c0c398d38475e63b280fe8' '8b00041911e67654b0bd9602125853a1a94f6155c5cac4f886507554c8324ee8' '5be21ae06708fb33021a536078cdbfcfe3f73e466694d28ba9e729ebfc575ed0' '762765be3d1b616bb0a33e8ce2d9a7661af5c1e8f4a56714a640268d3003eb68' '96c3639d9d193405f3e0db0c0be9f66dd9f01cfd24fde712572b9e31b29495d7' '834bd254b56ab71d73f59b3221f056c72f559553c04718e350ab2a3e2991afe0' 'ad6344badc91ad0630caacde83f7f9b97276f80d26a20619a87952be65492c65') validpgpkeys=( 'ABAF11C65A2970B130ABE3C479BE3E4300411886' # Linus Torvalds '647F28654894E3BD457199BE38DBBDC86092693E' # Greg Kroah-Hartman ) _kernelname=${pkgbase#linux} prepare() { cd ${_srcname} # add upstream patch patch -p1 -i ../patch-${pkgver} # fix naming schema in EXTRAVERSION of ck patch set sed -i -re "s/^(.EXTRAVERSION).*$/\1 = /" "../${_ckpatchname}" # Patch source with ck patchset patch -Np1 -i "../${_ckpatchname}" patch -Np1 -i "../unfuck_bfq.patch" # Patch source to unlock additional gcc CPU optimizatons # https://github.com/graysky2/kernel_gcc_patch patch -Np1 -i "../${_gcc_patch}" # Clean tree and copy ARCH config over make mrproper cp -Tf ../config.${CARCH} .config ### Optionally disable NUMA for 64-bit kernels only # (x86 kernels do not support NUMA) if [ -n "$_NUMAdisable" ]; then if [ "${CARCH}" = "x86_64" ]; then msg "Disabling NUMA from kernel config..." sed -i -e 's/CONFIG_NUMA=y/# CONFIG_NUMA is not set/' \ -i -e '/CONFIG_AMD_NUMA=y/d' \ -i -e '/CONFIG_X86_64_ACPI_NUMA=y/d' \ -i -e '/CONFIG_NODES_SPAN_OTHER_NODES=y/d' \ -i -e '/# CONFIG_NUMA_EMU is not set/d' \ -i -e '/CONFIG_NODES_SHIFT=6/d' \ -i -e '/CONFIG_NEED_MULTIPLE_NODES=y/d' \ -i -e '/# CONFIG_MOVABLE_NODE is not set/d' \ -i -e '/CONFIG_USE_PERCPU_NUMA_NODE_ID=y/d' \ -i -e '/CONFIG_ACPI_NUMA=y/d' ./.config fi fi ### Optionally use running kernel's config # code originally by nous; http://aur.archlinux.org/packages.php?ID=40191 if [ -n "$_use_current" ]; then if [[ -s /proc/config.gz ]]; then msg "Extracting config from /proc/config.gz..." # modprobe configs zcat /proc/config.gz > ./.config else warning "Your kernel was not compiled with IKCONFIG_PROC!" warning "You cannot read the current config!" warning "Aborting!" exit fi fi if [ "${_kernelname}" != "" ]; then sed -i "s|CONFIG_LOCALVERSION=.*|CONFIG_LOCALVERSION=\"${_kernelname}\"|g" ./.config sed -i "s|CONFIG_LOCALVERSION_AUTO=.*|CONFIG_LOCALVERSION_AUTO=n|" ./.config fi # set extraversion to pkgrel sed -ri "s|^(EXTRAVERSION =).*|\1 -${pkgrel}|" Makefile # don't run depmod on 'make install'.
