# 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-4.12 pkgver=4.12.8 pkgrel=2 _ckpatchversion=2 arch=('i686' 'x86_64') url="https://wiki.archlinux.org/index.php/Linux-ck" license=('GPL2') makedepends=('kmod' 'inetutils' 'bc' 'libelf') options=('!strip') _ckpatchname="patch-4.12-ck${_ckpatchversion}" _gcc_patch='enable_additional_cpu_optimizations_for_gcc_v4.9+_kernel_v3.15+.patch' source=("http://www.kernel.org/pub/linux/kernel/v4.x/${_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-${pkgver}.sign" "http://ck.kolivas.org/patches/4.0/4.12/4.12-ck${_ckpatchversion}/${_ckpatchname}.xz" "http://repo-ck.com/source/gcc_patch/${_gcc_patch}.gz" # 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' 'bonding-require-speed-duplex-only-for-802.3ad-alb-an.patch' 'bonding-ratelimit-failed-speed-duplex-update-warning.patch' 'mm-Revert-x86_64-and-arm64-ELF_ET_DYN_BASE-base.patch' ) sha256sums=('a45c3becd4d08ce411c14628a949d08e2433d8cdeca92036c7013980e93858ab' 'SKIP' '32b860911a3bafd5cd5bc813a427c90fad6eafdf607fa64e1b763b16ab605636' 'SKIP' '6d15f95ca23b46f7abdfa1315600daed7ed6843acc29587fd84c2be7937c8564' '0f3e4930c3a603cc99fffa9fcac0f2cf7c58fc14a7ef8557345358c0bcd2bf66' '200320c08e5c469b28be2b8b74de14397c9cfccb11ce3add07536e050c27a180' '8a7a3ec9dec36c6b30c0d8de9bc6beb418e6d3346225d2d85c7d6b77c4d00a78' '834bd254b56ab71d73f59b3221f056c72f559553c04718e350ab2a3e2991afe0' 'ad6344badc91ad0630caacde83f7f9b97276f80d26a20619a87952be65492c65' '48e0505438bb4ccc7a0e050a896122b490e8f1b1446aa3833841a9d4d7853d68' 'fc606711a922638d5cc4358f47f69f554d9e6eab1cec91f0b49f00911f399722' 'b830ce777543c0edd20a77d70f204c095f2429bb37151cd4a8c9dfae2af8d51a') validpgpkeys=( 'ABAF11C65A2970B130ABE3C479BE3E4300411886' # Linus Torvalds '647F28654894E3BD457199BE38DBBDC86092693E' # Greg Kroah-Hartman ) _kernelname=${pkgbase#linux} prepare() { cd "${srcdir}/${_srcname}" # add upstream patch patch -p1 -i "${srcdir}/patch-${pkgver}" # https://bugzilla.kernel.org/show_bug.cgi?id=196547 patch -Np1 -i ../bonding-ratelimit-failed-speed-duplex-update-warning.patch patch -Np1 -i ../bonding-require-speed-duplex-only-for-802.3ad-alb-an.patch # https://github.com/google/sanitizers/issues/837 # https://patchwork.kernel.org/patch/9886105/ patch -Np1 -i ../mm-Revert-x86_64-and-arm64-ELF_ET_DYN_BASE-base.patch # fix naming schema in EXTRAVERSION of ck patch set sed -i -re "s/^(.EXTRAVERSION).*$/\1 = /" "${srcdir}/${_ckpatchname}" # Patch source with ck patchset patch -Np1 -i "${srcdir}/${_ckpatchname}" # Patch source to unlock additional gcc CPU optimizatons # https://github.com/graysky2/kernel_gcc_patch patch -Np1 -i "${srcdir}/${_gcc_patch}" # Clean tree and copy ARCH config over make mrproper cat "${srcdir}/config.${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'.
