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.

bool "PS3 Advanced configuration options"
|
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.

|
help
|
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.
|
|
If unsure, choose the default (20) with the confidence that your
|
system will have optimal runtime performance.

|
help
|
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,
|
say N.

in the repository for later boot stages.

If in doubt, say N here and reduce the size of the kernel by a

small amount.

be disabled on the kernel command line using "ps3flash=off", to

of the PS3's LV1 hypervisor.
