TachSensor: Accept PowerState from configuration Accept the PowerState configuration parameter, similar to other sensors. This allows it to optionally be set to "Always", while still preserving the default of "On". Some systems have their chassis fans not tied to host power, so they can continue working, even when host powered off, and "Always" allows the BMC to continue to monitor them. Tested: Without this patch, or set to "On", the tachometers show RPM of 0, even though the fans are still running correctly, when host is powered off (but BMC and chassis fans still have power). After this patch, and setting "Always", the tachometers once again indicate proper RPM. Signed-off-by: Josh Lehan <krellan@google.com> Change-Id: I1774f0bec180f52e18d37500fcdd87d32620d519
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
