Kernel driver i2c-nforce2
|
|
-------------------------
|
|
|
|
Status: Well tested
|
|
|
|
Supported adapters:
|
|
* nVidia nForce2 SMBus PCI interface
|
|
(10de:0064, included in nForce2 MCP,
|
|
10de:0084, included in nForce2 Ultra 400 MCP)
|
|
Datasheet: not publically available, but seems to be similar to the
|
|
AMD-8111 SMBus 2.0 adapter.
|
|
|
|
* nVidia nForce3 SMBus PCI interface
|
|
(10de:00d4, included in nForce3 Pro150 MCP,
|
|
10de:00e4, included in nForce3 250Gb MCP)
|
|
Datasheet: same as for nForce2 SMBus PCI interface
|
|
|
|
* nVidia nForce4 SMBus PCI interface
|
|
(10de:0052, included in nForce4 MCP)
|
|
Datasheet: same as for nForce2 SMBus PCI interface

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

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