Off course !
Concerning the auto fan mode, I think that the interface:
auto_temp_off
auto_temp_min
auto_temp_max
is clear, so I'm going to implement that.
Concerning the channel configuration, as
adm1030 can select:
- ext temp for regulation
- max of the 2 channels
adm1031 can select:
- ext temp1 for fan1, ext temp2 for fan2
- ext temp1 for fan1 and fan2
- ext temp2 for fan1 and fan2
- max of 3 channels for fan1 and fan2
it is pretty hard to create a standard interface, so what I suggest, is
to create a file fan_auto_temp_select that would verbosely print the
values it can hold. Example for adm1030:
# cat fan_auto_temp_select
* 0 => manual mode
1 => temp2 controls fan1 temp3 controls fan2
2 => temp2 controls fan1 and fan2
3 => temp3 controls fan1 and fan2
4 => max controls fan1 and fan2
The star shows the current config.
Do you like this approach ? Is it possible to write as many bytes in the
buffer given to the show() interface ? Or do you have another idea ?
