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.
