   2 # backport Kconfig
   3 #
   4 # Some options are user-selectable ("BPAUTO_USERSEL_*")
   5 #
   6 # Most options, however, follow a few different schemes:
   7 #
   8 # A) An option that is selected by drivers ("select FOO") will be
   9 #    changed to "select BPAUTO_FOO" (if the option BPAUTO_FOO
  10 #    exists). The option BPAUTO_FOO then controls setting of the
  11 #    BPAUTO_BUILD_FOO option, which is a module, like this:
  12 #
  13 # config BPAUTO_BUILD_FOO
  14 #       tristate
  15 #       # or bool
  16 #
  17 #       # not possible on kernel < X.Y, build will fail if any
  18 #       # drivers are allowed to build on kernels < X.Y
  19 #       depends on KERNEL_X_Y
  20 #
  21 #       # don't build the backport code if FOO is in the kernel
  22 #       # already, but only if the kernel version is also >= X.Z;
  23 #       # this is an example of backporting where the version of
  24 #       # the FOO subsystem that we need is only available from
  25 #       # kernel version X.Z
  26 #       depends on !FOO || KERNEL_X_Z
  27 #
  28 #       # build if driver needs it (it selects BPAUTO_FOO)
  29 #       default m if BPAUTO_FOO
  30 #
  31 #       # or for build-testing (BPAUTO_USERSEL_BUILD_ALL is enabled)
  32 #       default m if BPAUTO_USERSEL_BUILD_ALL
  33 #
  34 # config BPAUTO_FOO
  35 #       bool
  36 #
  37 # This only works as-is if the kernel code is usable on any version,
  38 # otherwise the "&& !FOO" part needs to be different.
  39 #
  40 #
  41 # B) An option for code always present on some kernels (e.g. KFIFO).
  42 #    This simply depends on/sets the default based on the version:
  43 #
  44 # config BPAUTO_BUILD_KFIFO
  45 #       def_bool y
  46 #       depends on KERNEL_2_6_36
  47 #
  48 #
  49 # C) similarly, a kconfig symbol for an option, e.g.
  50 #    BPAUTO_OPTION_SOME_FIX (no examples provided) check git log
  51 #
  52 #
  53 # Variations are obviously possible.
  54 #

  59         default MODULES
  60
  61         help
  62         This symbol is necessary for the newer kconf tool, it looks
  63         for the "option modules" to control the 'm' state.

  99           This option selects all the compat code options
 100           that would otherwise only be selected by drivers.
 101
 102           It's only really useful for compat testing, so
 103           you probably shouldn't enable it.
