Add a FLASH ROM Storage Driver for the PS3:
- Implemented as a misc character device driver
- Uses a fixed 256 KiB buffer allocated from boot memory as the hypervisor
requires the writing of aligned 256 KiB blocks

This option enables support for the Sony PS3 game console
|
|
and other platforms using the PS3 hypervisor.
|
|
Support for this platform is not yet complete, so
|
|
enabling this will not result in a bootable kernel on a
|
|
PS3 system.

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.

not allocate this fixed buffer.
