Module Parameters
|
|
-----------------
|
|
|
|
* force_addr: int
|
|
Initialize the ISA address of the sensors
|
|
* force_i2c: int
|
|
Initialize the I2C address of the sensors
|
|
* init: int
|
|
(default is 1)
|
|
Use 'init=0' to bypass initializing the chip.
|
|
Try this if your computer crashes when you load the module.

Description
|
|
-----------
|
|
|
|
This driver implements support for ISA accesses *only* for
|
|
the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
|
|
We will refer to them collectively as Winbond chips.
|
|
|
|
This driver supports ISA accesses, which should be more reliable
|
|
than i2c accesses. Also, for Tyan boards which contain both a
|
|
Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
|
|
using this driver will avoid i2c address conflicts and complex
|
|
initialization that were required in the w83781d driver.
|
|
|
|
If you really want i2c accesses for these Super I/O chips,
|
|
use the w83781d driver. However this is not the preferred method
|
|
now that this ISA driver has been developed.
|
|
|
|
The w83627_HF_ uses pins 110-106 as VID0-VID4. The w83627_THF_ uses the
|
|
same pins as GPIO[0:4]. Technically, the w83627_THF_ does not support a
|
|
VID reading. However the two chips have the identical 128 pin package. So,
|
|
it is possible or even likely for a w83627thf to have the VID signals routed
|
|
to these pins despite their not being labeled for that purpose. Therefore,
|
|
the w83627thf driver interprets these as VID. If the VID on your board
|
|
doesn't work, first see doc/vid in the lm_sensors package[1]. If that still
|
|
doesn't help, you may just ignore the bogus VID reading with no harm done.
|
|
|
|
For further information on this driver see the w83781d driver documentation.
