nvme devices report temperature information in the controller information (for limits) and in the smart log. Currently, the only means to retrieve this information is the nvme command line interface, which requires super-user privileges. At the same time, it would be desirable to be able to use NVMe temperature information for thermal control. This patch adds support to read NVMe temperatures from the kernel using the hwmon API and adds temperature zones for NVMe drives. The thermal subsystem can use this information to set thermal policies, and userspace can access it using libsensors and/or the "sensors" command. Example output from the "sensors" command: nvme0-pci-0100 Adapter: PCI adapter Composite: +39.0°C (high = +85.0°C, crit = +85.0°C) Sensor 1: +39.0°C Sensor 2: +41.0°C Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Keith Busch <kbusch@kernel.org>
