  18. ### PATCH AND BUILD OPTIONS
  19. # taken from graysky linux-ck see: https://aur.archlinux.org/packages/linux-ck
  20. # Set these variables to ANYTHING (yes or no or 1 or 0 or "I like icecream") to enable them
  21. #
  22.  
  23. _NUMA_off=yes       # Disable NUMA in kernel config
  24.  
  25. ### DOCS
  26. # Starting with the 3.6.6-3 release, this package ships with the kernel-3x-gcc47-x.patch.
  27. # This allows users an expanded scope of CPU specific options.
  28. # Consult the following resources to understand which option is right for you application:
  29. #
  30. # http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel
  31. # http://en.gentoo-wiki.com/wiki/Safe_Cflags/AMD
  32. # http://www.linuxforge.net/docs/linux/linux-gcc.php
  33. # http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html
  34.  
  35. # DETAILS FOR using 'make localmodconfig'
  36. # As of mainline 2.6.32, running with this option will only build the modules that you currently have
  37. # probed in your system VASTLY reducing the number of modules built and the build time to do it.
  38. #
  39. # WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
  40. #
  41. # To keep track of which modules are needed for your specific system/hardware, give my module_db script
  42. # a try: http://aur.archlinux.org/packages.php?ID=41689  Note that if you use my script, this PKGBUILD
  43. # will auto run the 'sudo modprobed_db reload' for you to probe all the modules you have logged!
  44. #
  45. # More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed_db
  46.  
  47. # DETAILS FOR running kernel's config
  48. # Enabling this option will use the .config of the RUNNING kernel rather than the ARCH defaults.
  49. # Useful when the package gets updated and you already went through the trouble of customizing your
  50. # config options.  NOT recommended when a new kernel is released, but again, convenient for package bumps.
  51.  
  52. # DRTAILS FOR _NUMA_off=yes
  53. # Since 99.9% of users do not have multiple CPUs but do have multiple cores in one CPU
  54. # see, https://bugs.archlinux.org/task/31187
