This option enables support for the Sony PS3 game console
|

and other platforms using the PS3 hypervisor. Enabling this
|

option will allow building otheros.bld, a kernel image suitable

for programming into flash memory, and vmlinux, a kernel image

suitable for loading via kexec.

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

This option is only for experts who may have the desire to fine
|

tune the pagetable size on their system. The value here is

expressed as the log2 of the page table size. Valid values are
|
|
18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.

This option will enable kernel support to take advantage of the

per device dynamic DMA page table management provided by the Cell
|
|
processor's IO Controller. This support incurs some runtime
|
|
overhead and also slightly increases kernel memory usage. The

current implementation should be considered experimental.
|

This support is mainly for Linux kernel development. If unsure,
