20 | AMD-8111 SMBus 2.0 adapter. |

| 27 | Description | |
| 28 | ----------- | |
| 29 | ||
| 30 | i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP. | |
| 31 | ||
| 32 | If your 'lspci -v' listing shows something like the following, | |
| 33 | ||
| 34 | 00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2) | |
| 35 | Subsystem: Asustek Computer, Inc.: Unknown device 0c11 | |
| 36 | Flags: 66Mhz, fast devsel, IRQ 5 | |
| 37 | I/O ports at c000 [size=32] | |
| 38 | Capabilities: <available only to root> | |
| 39 | ||
| 40 | then this driver should support the SMBuses of your motherboard. | |
| 41 | ||

| 43 | Notes | |
| 44 | ----- | |
| 45 | ||
| 46 | The SMBus adapter in the nForce2 chipset seems to be very similar to the | |
| 26f95c4a | 47 | SMBus 2.0 adapter in the AMD-8111 south bridge. However, I could only get |
| 1da177e4 LT |
48 | the driver to work with direct I/O access, which is different to the EC |
| 49 | interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the | |
| 50 | Asus A7N8X lists two SMBuses, both of which are supported by this driver. |
