[lm-sensors] [PATCH 0/3] First shot at a hwmon device name mapper

[Jean Delvare]

Hi all,

As discussed lately on this list, here is a first shot at a helper
binary that resolves libsensors chip names to kernel device names and
back.

This is really a proof of concept at this point. Everything can still
be discussed and changed, just speak up if you see any problem or to
ask for improvements. Specifically I have no preference for the tool's
name or its command line interface, so if you can think of anything
better, just let me know.

I tried with udev, but that doesn't work - if I understand corretly,
device rename support needs explicit kernel support per subsystem.
The networking subsystem does it with dev_change_name(). Other than that
there is device_rename(), which is hardly used.

So I guess we have no other choice than something like this, unless we go
radical and start using per-driver names (coretemp0 instead of hwmonX).
But I think even that would not be reboot-safe, for example on a system
with multiple sensors of the same type connected to different i2c busses.
Anyway, not sure if that would be a good idea to start with.
