i2cdetect outputs on Intel x58 chipsets wanted
in [Kernel]

From: Fernand LONE SANG on 29 Jul 2010 05:00 Hello everyone. My apology for multiple reception of this mail. As i did not get much answer from the linux-i2c mailing list, i try this one which is bigger. I am probably off-topic so feel free to skip to the next thread ;) I am currently trying to reach a SMBus slave component located in the I/O Hub (IOH) on Intel x58 chipsets. According to Intel specifications, this component enable server manageability. As my motherboard (DX58SO E29331-503) does not seem to have this component and as I did not manage to get in touch with an Intel technician for help, i'm looking for some kind people, with an Intel x58 chipset, who can send me by email their outputs from the i2cdectect tool so i can identify the motherboard version that have this component. For ones who can help me, you should first load the i2c-dev and i2c-i801 kernel modules: $ sudo modprobe i2c-dev $ sudo modprobe i2c-i801 Then, you should install i2c-tools to get i2cdetect. e.g., for debian based distribution: $ sudo apt-get install i2c-tools Now i would like you to run "i2cdetect -l" to identify the i2c adapter available on your computer and then run i2cdetect on the Intel i801 adapter. For example: $ sudo i2cdetect -l i2c-0 i2c nouveau-0000:02:00.0-0 I2C adapter i2c-1 i2c nouveau-0000:02:00.0-1 I2C adapter i2c-2 smbus SMBus I801 adapter at 3000 SMBus adapter $ sudo i2cdetect 2 ... At this stage, a warning message will appear stating that this manipulation can confuse your i2c bus and it will ask you whether to continue or not. Type 'Yes'. Then, it will output some numbers on the screen. It is this output what i need. Additionnally, if you can send me the output of dmidecode so i can identify the exact motherboard model you have, it will be perfect. $ sudo i2cdetect 2 > i2cdetect.out $ sudo dmidecode > dmidecode.out Thanks everyone for your help. I really appreciate. Sorry again for being off-topic. -- Fernand LONE SANG -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

SuperMicro C7X58 v1.0 (there is a V1.1 board now), latest BIOS (1.1a). dmidecode information is useless on this board. 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- 08 -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- 18 -- 1a -- 1c -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- 2e -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- 3e -- 40: -- -- -- -- 44 -- -- -- -- -- -- -- -- -- -- -- 50: 50 -- 52 -- 54 -- -- -- -- -- -- -- -- -- -- -- 60: -- 61 -- -- -- -- -- -- -- 69 -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- This is a X58 IOH rev 12 (there is a newer stepping of the X58). Also, it could well be that the BIOS can configure the X58 IOH to hide devices. May also depend on what the firmware is doing to the X58 embedded controller. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
