- ### PATCH AND BUILD OPTIONS
- # Set these variables to ANYTHING (yes or no or 1 or 0 or "I like icecream") to enable them
- #
- _makenconfig= # Tweak kernel options prior to a build via nconfig
- _localmodcfg= # Compile ONLY probed modules
- _use_current= # Use the current kernel's .config file
- _BFQ_enable_= # Enable BFQ as the default I/O scheduler
- _NUMAdisable=y # Disable NUMA in kernel config
- ### DOCS
- # Starting with the 3.6.9-3 release, this package ships with the kernel-3x-gcc47-x.patch.
- # This allows users an expanded scope of CPU specific options.
- # Consult the following resources to understand which option is right for you application:
- #
- # http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel
- # http://en.gentoo-wiki.com/wiki/Safe_Cflags/AMD
- # http://www.linuxforge.net/docs/linux/linux-gcc.php
- # http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html
- # DETAILS FOR _localmodcfg=
- # 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 - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
- #
- # To keep track of which modules are needed for your specific system/hardware, give my module_db script
- # a try: http://aur.archlinux.org/packages.php?ID=41689 Note that if you use my script, this PKGBUILD
- # will auto run the 'sudo modprobed_db reload' for you to probe all the modules you have logged!
- #
- # More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed_db
- # DETAILS FOR _use_current=
- # 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.
- # DETAILS FOR _BFQ_enable=
- # Alternative I/O scheduler by Paolo. For more, see: http://algo.ing.unimo.it/people/paolo/disk_sched/
- # DETAILS FOR _NUMAdisable=
- # Since 99.9% of users do not have multiple CPUs but do have multiple cores in one CPU
- # see, https://bugs.archlinux.org/task/31187
