Kernel driver i2c-ismt¶
- Supported adapters:
- Intel S12xx series SOCs
- Bill Brown <email@example.com>
- 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
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:
00:13.0 System peripheral: Intel Corporation Centerton SMBus 2.0 Controller 0 00:13.1 System peripheral: Intel Corporation Centerton SMBus 2.0 Controller 1
