menu "PS3 Platform Options"
depends on PPC_PS3
config PS3_ADVANCED
depends on PPC_PS3
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.
config PS3_HTAB_SIZE
depends on PPC_PS3
int "PS3 Platform pagetable size" if PS3_ADVANCED
range 18 20
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.
config PS3_DYNAMIC_DMA
depends on PPC_PS3 && EXPERIMENTAL
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.
config PS3_USE_LPAR_ADDR
depends on PPC_PS3 && EXPERIMENTAL
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.
config PS3_VUART
depends on PPC_PS3
bool "PS3 Virtual UART support" if PS3_ADVANCED
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.
config PS3_PS3AV
tristate "PS3 AV settings driver" if PS3_ADVANCED
depends on PS3_VUART
default y
help
Include support for the PS3 AV Settings driver.
This support is required for graphics and sound. In
general, all users will say Y or M.
config PS3_SYS_MANAGER
bool "PS3 System Manager driver" if PS3_ADVANCED
depends on PS3_VUART
default y
help
Include support for the PS3 System Manager.
This support is required for system control. In
general, all users will say Y.
