# Maintainer: Joan Figueras # Contributor: Torge Matthies # Contributor: Jan Alexander Steffens (heftig) # Contributor: Yoshi2889 # Contributor: Tobias Powalowski # Contributor: Thomas Baechler ## ## The following variables can be customized at build time. Use env or export to change at your wish ## ## Example: env _microarchitecture=98 use_numa=n use_tracers=n makepkg -sc ## ## Look inside 'choose-gcc-optimization.sh' to choose your microarchitecture ## Valid numbers between: 0 to 99 ## Default is: 0 => generic ## Good option if your package is for one machine: 98 (Intel native) or 99 (AMD native) if [ -z ${_microarchitecture+x} ]; then _microarchitecture=0 fi ## Disable NUMA since most users do not have multiple processors. Breaks CUDA/NvEnc. ## Archlinux and Xanmod enable it by default. ## Set variable "use_numa" to: n to disable (possibly increase performance) ## y to enable (stock default) if [ -z ${use_numa+x} ]; then use_numa=y fi ## For performance you can disable FUNCTION_TRACER/GRAPH_TRACER. Limits debugging and analyzing of the kernel. ## Stock Archlinux and Xanmod have this enabled. ## Set variable "use_tracers" to: n to disable (possibly increase performance) ## y to enable (stock default) if [ -z ${use_tracers+x} ]; then use_tracers=y fi ## Choose between GCC and CLANG config (default is GCC) if [ -z ${_compiler+x} ]; then _compiler=gcc fi # Compress modules with ZSTD (to save disk space) if [ -z ${_compress_modules+x} ]; then _compress_modules=n fi # Compile ONLY used modules to VASTLY reduce the number of modules built # and the build time. # # 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 read the database kept if it exists # # More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db if [ -z ${_localmodcfg} ]; then _localmodcfg=n fi # Tweak kernel options prior to a build via nconfig _makenconfig= ### IMPORTANT: Do no edit below this line unless you know what you're doing pkgbase=linux-xanmod-anbox _major=5.14 pkgver=${_major}.17 _branch=5.x xanmod=1 pkgrel=${xanmod} pkgdesc='Linux Xanmod with ashmem and binder enabled for Anbox - Current Stable (STABLE)' url="http://www.xanmod.org/" arch=(x86_64) license=(GPL2) makedepends=( bc cpio kmod libelf perl tar xz ) if [ "${_compiler}" = "clang" ]; then makedepends+=(clang llvm lld python) fi options=('!strip') _srcname="linux-${pkgver}-xanmod${xanmod}" source=("https://cdn.kernel.org/pub/linux/kernel/v${_branch}/linux-${_major}.tar."{xz,sign} "https://github.com/xanmod/linux/releases/download/${pkgver}-xanmod${xanmod}/patch-${pkgver}-xanmod${xanmod}.xz" choose-gcc-optimization.sh) #"patch-${pkgver}-xanmod${xanmod}.xz::https://sourceforge.net/projects/xanmod/files/releases/stable/${pkgver}-xanmod${xanmod}/patch-${pkgver}-xanmod${xanmod}.xz/download" validpgpkeys=( 'ABAF11C65A2970B130ABE3C479BE3E4300411886' # Linux Torvalds '647F28654894E3BD457199BE38DBBDC86092693E' # Greg Kroah-Hartman ) # Archlinux patches _commit="ec9e9a4219fe221dec93fa16fddbe44a34933d8d" _patches=() for _patch in ${_patches[@]}; do #source+=("${_patch}::https://git.archlinux.org/svntogit/packages.git/plain/trunk/${_patch}?h=packages/linux&id=${_commit}") source+=("${_patch}::https://raw.githubusercontent.com/archlinux/svntogit-packages/${_commit}/trunk/${_patch}") done sha256sums=('7e068b5e0d26a62b10e5320b25dce57588cbbc6f781c090442138c9c9c3271b2' 'SKIP' '676138bf73625951d93721e42a77208536f99f33b0fd9a1c850b8b5708ad73f2' '1ac18cad2578df4a70f9346f7c6fccbb62f042a0ee0594817fdef9f2704904ee') export KBUILD_BUILD_HOST=${KBUILD_BUILD_HOST:-archlinux} export KBUILD_BUILD_USER=${KBUILD_BUILD_USER:-makepkg} export KBUILD_BUILD_TIMESTAMP=${KBUILD_BUILD_TIMESTAMP:-$(date -Ru${SOURCE_DATE_EPOCH:+d @$SOURCE_DATE_EPOCH})} prepare() { cd linux-${_major} # Apply Xanmod patch patch -Np1 -i ../patch-${pkgver}-xanmod${xanmod} msg2 "Setting version..." scripts/setlocalversion --save-scmversion echo "-$pkgrel" > localversion.10-pkgrel echo "${pkgbase#linux-xanmod-anbox}" > localversion.20-pkgname # Archlinux patches local src for src in "${source[@]}"; do src="${src%%::*}" src="${src##*/}" [[ $src = *.patch ]] || continue msg2 "Applying patch $src..." patch -Np1 < "../$src" done # Applying configuration cp -vf CONFIGS/xanmod/${_compiler}/config .config # enable LTO_CLANG_THIN if [ "${_compiler}" = "clang" ]; then scripts/config --disable LTO_CLANG_FULL # Anbox compatibility msg2 "Enabling ashmem and binder modules" scripts/config --enable CONFIG_ASHMEM scripts/config --enable CONFIG_ANDROID scripts/config --enable CONFIG_ANDROID_BINDER_IPC scripts/config --enable CONFIG_ANDROID_BINDERFS scripts/config --set-str CONFIG_ANDROID_BINDER_DEVICES "binder,hwbinder,vndbinder" scripts/config --enable LTO_CLANG_THIN _LLVM=1 fi # CONFIG_STACK_VALIDATION gives better stack traces.
