int "PS3 Platform pagetable size"

default 20
|
|
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.

bool "PS3 Platform dynamic DMA page table management"
|

default n
|
|
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.

bool "PS3 use lpar address space"
|

default y
|
|
help
|
|
This option is solely for experimentation by experts. Disables
|
|
translation of lpar addresses. SPE support currently won't work
|
|
without this set to y.
|
|
|
|
If you have any doubt, choose the default y.

default y

help
|
|
Include support for the PS3 Virtual UART.
|
|
|
|
This support is required for several system services
|
|
including the System Manager and AV Settings. In
|
|
general, all users will say Y.
