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

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

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

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