# 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=25 use_numa=n use_tracers=n use_pds=n makepkg -sc ## ## Look inside 'choose-gcc-optimization.sh' to choose your microarchitecture ## Valid numbers between: 0 to 42 ## Default is: 0 => generic ## Good option if your package is for one machine: 42 => 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 ## Enable CONFIG_USER_NS_UNPRIVILEGED flag https://aur.archlinux.org/cgit/aur.git/tree/0001-ZEN-Add-sysctl-and-CONFIG-to-disallow-unprivileged-C.patch?h=linux-ck ## Set variable "use_ns" to: n to disable (stock Xanmod) ## y to enable (stock Archlinux) if [ -z ${use_ns+x} ]; then use_ns=n fi # Compile ONLY used modules to VASTLYreduce 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 ${_localmodcfg} ]; then _localmodcfg=n fi # Tweak kernel options prior to a build via nconfig _makenconfig= ### IMPORTANT: Do no edit below this line unless you know what you're doing pkgbase=linux-xanmod-anbox pkgver=5.9.14 _major=5.9 _branch=5.x xanmod=1 pkgrel=${xanmod} pkgdesc='Linux Xanmod with ashmem and binder enabled for Anbox' url="http://www.xanmod.org/" arch=(x86_64) license=(GPL2) makedepends=( xmlto kmod inetutils bc libelf cpio ) 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 '0001-ZEN-Add-sysctl-and-CONFIG-to-disallow-unprivileged-CLONE_NEWUSER.patch') validpgpkeys=( 'ABAF11C65A2970B130ABE3C479BE3E4300411886' # Linux Torvalds '647F28654894E3BD457199BE38DBBDC86092693E' # Greg Kroah-Hartman ) # Archlinux patches _commits="" for _patch in $_commits; do source+=("${_patch}.patch::https://git.archlinux.org/linux.git/patch/?id=${_patch}") done sha256sums=('3239a4ee1250bf2048be988cc8cb46c487b2c8a0de5b1b032d38394d5c6b1a06' 'SKIP' '61272350b30a72ccd8c6e4336073f8a178ff476cf8ffb76c11ab456f185da681' '2c7369218e81dee86f8ac15bda741b9bb34fa9cefcb087760242277a8207d511' '6c66dba73251440352f93ff32b72f5dd49536d0f17ef9347867660fd3a626991') # If use_cachy=y or use_cacule=y then advice user to install the new package if [ "$use_cachy" = "y" ] || [ "$use_cacule" = "y" ]; then echo "Cachy is now Cacule.
