i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2, |
|---|
| 34 |
nForce3 and nForce4 MCP. |
|---|
| 35 |
|
|---|
| 36 |
If your 'lspci -v' listing shows something like the following, |
|---|
| 37 |
|
|---|
| 38 |
00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2) |
|---|
| 39 |
Subsystem: Asustek Computer, Inc.: Unknown device 0c11 |
|---|
| 40 |
Flags: 66Mhz, fast devsel, IRQ 5 |
|---|
| 41 |
I/O ports at c000 [size=32] |
|---|
| 42 |
Capabilities: <available only to root> |
|---|
| 43 |
|
|---|
| 44 |
then this driver should support the SMBuses of your motherboard. |

The SMBus adapter in the nForce2/3/4 chipset seems to be very similar to the |
|---|
| 51 |
SMBus 2.0 adapter in the AMD-8111 southbridge. However, I could only get the |
|---|
| 52 |
driver to work with direct I/O access, which is different to the EC interface |
|---|
| 53 |
of the AMD-8111. |
|---|
| 54 |
Tested on Asus A7N8X. The ACPI DSDT table of the Asus A7N8X lists two SMBuses, |
|---|
| 55 |
both of which are supported by this driver. |
