menu "PS3 Platform Options"
depends on PPC_PS3
config PS3_HTAB_SIZE
depends on PPC_PS3
int "PS3 Platform pagetable size"
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.
