      tools/thermal: Introduce tmon, a tool for thermal subsystem · 94f69966
      Jacob Pan 提交于
      Increasingly, Linux is running on thermally constrained devices. The simple
      thermal relationship between processor and fan has become past for modern
      computers.
      
      As hardware vendors cope with the thermal constraints on their products,
      more sensors are added, new cooling capabilities are introduced. The
      complexity of the thermal relationship can grow exponentially among cooling
      devices, zones, sensors, and trip points. They can also change dynamically.
      
      To expose such relationship to the userspace, Linux generic thermal layer
      introduced sysfs entry at /sys/class/thermal with a matrix of symbolic
      links, trip point bindings, and device instances. To traverse such
      matrix by hand is not a trivial task. Testing is also difficult in that
      thermal conditions are often exception cases that hard to reach in
      normal operations.
      
      TMON is conceived as a tool to help visualize, tune, and test the
      complex thermal subsystem.
