i have a Riverbed Steelhead 1050L that i am moving from the vendors linux install to gentoo. the w83793 hwmon chip driver on the i2c bus is not providing temp{n}fan_map virtual files mentioned at /usr/src/linux/Documentation/hwmon/w83793. if i unload the driver then manually set fan_map registers with i2cset i am then able to control the fans with the reloaded driver and pwmconfig. however these values are reset on reboot either by the hwmon chip or the ipmi daughter card. not even sure if these virtual files mentioned in the docs ever existed.

i have been using the following to remove the fans from smart fan control and putting them in manual control.

i2cset 0 0x2f 0x00 0x02 &&
 i2cset 0 0x2f 0x02 0x00 &&
 i2cset 0 0x2f 0x02 0x00 &&
 i2cset 0 0x2f 0x02 0x00

the other i2c paste was wrong. this is correct.

i2cset 0 0x2f 0x00 0x02 &&
 i2cset 0 0x2f 0x01 0x00 &&
 i2cset 0 0x2f 0x02 0x00 &&
 i2cset 0 0x2f 0x06 0x00

Is this still an issue with recent kernels?
Comment 5 kundarsa@gmail.com 2018-06-26 00:19:42 UTC
i no longer have a computer with this hwmon chip.

i suggest to close the issue and reopen if another user can confirm issue still exists.
