Several hardware features of SGI's IOC4 I/O controller chip require timing-related driver calculations dependent upon the PCI bus speed. This patch enables the core IOC4 driver code to detect the actual bus speed and store a value that can later be used by the IOC4 subdrivers as needed.

This option enables basic support for the SGI IOC4-based Base IO
|
|
controller card. This option does not enable any specific
|
|
functions on such a card, but provides necessary infrastructure
|
|
for other drivers to utilize.

If you have an SGI Altix with an IOC4-based
|
|
I/O controller say Y. Otherwise say N.
