Module Parameters
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
* bus_speed (unsigned int)
|
||
|
|
Allows changing of the bus speed. Normally, the bus speed is set by the BIOS
|
||
|
|
and never needs to be changed. However, some SMBus analyzers are too slow for
|
||
|
|
monitoring the bus during debug, thus the need for this module parameter.
|
||
|
|
Specify the bus speed in kHz.
|
||
|
|
Available bus frequency settings:
|
||
|
|
0 no change
|
||
|
|
80 kHz
|
||
|
|
100 kHz
|
||
|
|
400 kHz
|
||
|
|
1000 kHz

Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The S12xx series of SOCs have a pair of integrated SMBus 2.0 controllers
|
||
|
|
targeted primarily at the microserver and storage markets.
|
||
|
|
|
||
|
|
The S12xx series contain a pair of PCI functions. An output of lspci will show
|
||
|
|
something similar to the following:
