 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.

 41         help
 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.

 96 
 97           This support is intended for bootloaders that need to store data
 98           in the repository for later boot stages.
 99 
100           If in doubt, say N here and reduce the size of the kernel by a

139           As this driver needs a fixed buffer of 256 KiB of memory, it can
140           be disabled on the kernel command line using "ps3flash=off", to
141           not allocate this fixed buffer.
