I've been trying to work out how to do this through dynamic sysfs
attributes, but I have not found a way to create arbitrary attributes
like this. It's not hard to define them at kernel compile time, but
selecting the right number of sensors to compile in seems arbitrary. My
Inspiron 9200 has 4 sensors, and who knows how many next year's model
will have. It just doesn't seem like the Linux Kernel way of doing
things to arbitrarily limit it like this.
I've looked into several ways of creating sysfs attributes, but haven't
found anything that works right/well. One of the most interesting was
in this past LKML thread - http://lkml.org/lkml/2004/8/20/287 If I
could replace the sysfs_attr_show() with my own, I believe that might
work (the attribute is passed into the function, so the name should be
available).
It's odd that it's so easy to compile sysfs attributes into the kernel,
but nobody seems to know how to generate them dynamically.
Thoughts? Suggestions?
Thanks,
Frank
