Description
|
|
-----------
|
|
|
|
i2c-viapro is a true SMBus host driver for motherboards with one of the
|
|
supported VIA south bridges.
|
|
|
|
Your /proc/pci or lspci -n listing must show one of these :
|
|
|
|
device 1106:3050 (VT82C596A function 3)
|
|
device 1106:3051 (VT82C596B function 3)
|
|
device 1106:3057 (VT82C686 function 4)
|
|
device 1106:3074 (VT8233)
|
|
device 1106:3147 (VT8233A)
|
|
device 1106:8235 (VT8231 function 4)
|
|
device 1106:3177 (VT8235)
|
|
device 1106:3227 (VT8237R)
|
|
device 1106:3337 (VT8237A)
|
|
device 1106:3287 (VT8251)
|
|
device 1106:8324 (CX700)
|
|
|
|
If none of these show up, you should look in the BIOS for settings like
|
|
enable ACPI / SMBus or even USB.
|
|
|
|
Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
|
|
VT8231), this driver supports I2C block transactions. Such transactions
|
|
are mainly useful to read from and write to EEPROMs.
|
|
|
|
The CX700 additionally appears to support SMBus PEC, although this driver
|
|
doesn't implement it.
