Add threshold value scanning logic into cpusensor Threshold values of a CPU sensor can be changed at runtime by BIOS based on the thermal policy changes of the host machine. So this commit adds runtime scanning logic for reading threshold values from hwmon subsystem attributes. Tested: Check threshold properties in xyz.openbmc_projects.CPUSensor. All threshold vaues should reflect peci hwmon values dynamically. Change-Id: Ib5b0ce72f567437e69879a7e655d6f34f156013e Signed-off-by: Jae Hyun Yoo <jae.hyun.yoo@linux.intel.com>
dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.
runtime re-configurable from d-bus (entity-manager or the like)
isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible
async single-threaded: uses sdbusplus/asio bindings
multiple data inputs: hwmon, d-bus, direct driver access
