New Thermal Library & Temperature Capture Tool Readied For Linux 5.19
Back in February I wrote about the new thermal library and "thermometer" tool being worked on by Linaro's Daniel Lezcano. The library relies on Netlink notifications amd all the work combined is designed to improve user-space's dealings with the Linux kernel's thermal framework.
The in-tree thermometer tool allows for capturing temperatures from thermal zones defined in a configuration file, is low-overhead, and can be easily fed into other tooling like GNU Plot. The new thermal daemon is intended as a reference/example for writing new daemons around the Linux thermal library.
The new library, thermometer tool, and daemon are all part of the thermal subsystem's "linux-next" branch ahead of the Linux 5.19 merge window.
