  13           This option enables support for the Sony PS3 game console
  14           and other platforms using the PS3 hypervisor.  Enabling this
  15           option will allow building otheros.bld, a kernel image suitable
  16           for programming into flash memory, and vmlinux, a kernel image
  17           suitable for loading via kexec.

  25         help
  26           This gives you access to some advanced options for the PS3. The
  27           defaults should be fine for most users, but these options may make
  28           it possible to better control the kernel configuration if you know
  29           what you are doing.
  30
  31           Note that the answer to this question won't directly affect the
  32           kernel: saying N will just cause the configurator to skip all
  33           the questions about these options.
  34
  35           Most users should say N to this question.

  43           This option is only for experts who may have the desire to fine
  44           tune the pagetable size on their system.  The value here is
  45           expressed as the log2 of the page table size.  Valid values are
  46           18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.

  56           This option will enable kernel support to take advantage of the
  57           per device dynamic DMA page table management provided by the Cell
  58           processor's IO Controller.  This support incurs some runtime
  59           overhead and also slightly increases kernel memory usage.  The
  60           current implementation should be considered experimental.
  61
  62           This support is mainly for Linux kernel development.  If unsure,
  63           say N.
