thanks for doing so. The patchset needs the interface introduced in patch 9 and 10 to build the sensor nodes in the device tree and to generate shutdown events which is important for the machine. > 9 I've left for now, since Corey has comments. It's patch 10 in fact which is about the SET_SENSOR_READING command. I think this is the most complex command in the IPMI specs ... It's not a strong requirement for the firmware but as I have started it I am trying to reach a minimal and correct implementation ... It really is giving me headaches tough. I am glad that Corey is giving some support.
