ps3: Introduce CONFIG_PS3_ADVANCED, as suggested by Roman Zippel, and use it to control questions about PS3 subsystems that may not be obvious for the casual user. This gets rid of the following warning on non-powerpc platforms: | drivers/video/Kconfig:1604:warning: 'select' used by config symbol 'FB_PS3' refer to undefined symbol 'PS3_PS3AV' Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Acked-by: Geoff Levand <geoffrey.levand@am.sony.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

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.

int "PS3 Platform pagetable size" if PS3_ADVANCED

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.

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.
