This option enables kernel support for the Vector Scaler extensions
|
||||
to the PowerPC processor. The kernel currently supports saving and
|
||||
restoring VSX registers, and turning on the 'VSX enable' bit so user
|
||||
processes can execute VSX instructions.
|
||||
|
||||
This option is only useful if you have a processor that supports
|
||||
VSX (P7 and above), but does not have any affect on a non-VSX
|
||||
CPUs (it does, however add code to the kernel).
