Merged for the Linux 6.15 kernel last week was the big set of hardware monitoring “HWMON” subsystem updates with new hardware support as well as a few new sensor drivers.
The new HWMON drivers this cycle included the HTU31, Congatec Board Controller, and TI INA233. The HTU31 is a temperature and humidity sensor. Should you have an HTU31 IC in any of your industrial equipment or custom electronic designs, Linux 6.15 is now able to read the sensor information on the mainline kernel. The Congatec Board Controller is for the company’s micro-controller that takes care of embedded/EC features on their systems. This HWMON driver gets various current and voltage information exposed along with multiple temperature sensors and other information exposed under Linux. The TI INA233 current/power monitor IC is designed for servers, telecom infrastructure, HPC environments, battery chargers, and more.
When it comes to new hardware support tacked onto existing HWMOn drivers, there is now support for sensor monitoring on the ASUS X670E-PRO WIFI motherboard, support for temperature monitoring with the AMD Cyan Skillfish APU found within the Sony Playstation, and also sensor monitoring for the AMD BC-250 Bitcoin/crypto mining card.
There’s been a fair amount of work recently adapting the AMD BC-250 to new uses under Linux including experimental Vulkan support.
The LM90 driver has also tacked on support for the NCT7716, NCT7717 and NCT7718 ICs. The Dell SMM driver is also compatible with reading more fan speeds than was otherwise previously able to expose.
