Hi all,
I have two compute nodes on a machine that are both running embedded Linux. The nodes are connected to each other over Ethernet.
The both have an i2c bus. Node A has a thermal sensor. Node B has three fans.
Right now I have a user space application running on node B that uses ssh to read from node A's thermal sensor and then adjust the fan speeds accordingly. I am wondering if there's away instead to have a hwmon driver running on Node B for the thermal monitor running on node A. This way I could get rid of the user space application and replace it with something a little bit more standard like thermald.
Is this something that people have done? Maybe if not this specifically, how about a driver for a device over the network?
The "standard" way of doing something like this seems to be to have a daemon on node A, which forwards data to a daemon on node B, which pretends to be a bus on node B. Look at the fuse user space file system for an example of this. -- All Rights Reversed.
