Could anyone advise how I can make use i2c-i801 and/or i2c-dev to access ICH6 SMBus controller on a PC motherboard? I have Linux 2.6.10 and loaded i2c-core, i2c-i801and i2c-dev modules. lsmod command gave me the following info: # lsmod Module Size Used by i2c_dev 8320 0 i2c_sensor 3968 0 i2c_i801 8716 0 i2c_core 16272 3 i2c_dev,i2c_sensor,i2c_i801 It seems that i2c-i801 is not used by other modules. Thanks.

Dear Sir, I am new to Linux and Device driver programming. I am trying to write a device driver software module to access the ICH6 SMBus controller on the motherboard of our PC running Linux 2.6.10 kernel. I configured my 2.6.10 kernel to have I2C built-in support and your i801 module loaded. Then I loaded the i2c-dev interface module and wrote a short application software to test the functions for SMBus. After my application opened the /dev/i2c device, I received messages saying "i2c-adaptor: i2c-0 -- I2C level transfer not support" when my application software called the read and write function of the i2c-dev module. Further tracking inside the i2c-dev module shew that the algorithm parameter adap->algo->master_xfer = NULL. That means the i801 driver was not properly loaded by the i2c-dev module. Could you advise how I can make use of the i801 module and your i2c-dev module to access the ICH6 SMBus controller? Thanks a lot in advance. Michael Gu _____ Find your next car at Yahoo!
