74e95d5de9
Adds support for the PS3 virtual UART (vuart). The vuart provides a bi-directional byte stream data link between logical partitions. This is needed for the ps3 graphics driver and the ps3 power control support to be able to communicate with the lv1 policy module.

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.

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.

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.
