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

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

  42           This option is only for experts who may have the desire to fine
  43           tune the pagetable size on their system.  The value here is
  44           expressed as the log2 of the page table size.  Valid values are
  45           18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.
  46
  47           If unsure, choose the default (20) with the confidence that your
  48           system will have optimal runtime performance.

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

  70           translation of lpar addresses.  SPE support currently won't work

 138           be disabled on the kernel command line using "ps3flash=off", to
 139           not allocate this fixed buffer.
