About this tag
The hwmon tag on WindowsForum.com covers the Linux kernel's hardware monitoring subsystem, which exposes sensors like temperatures, fan speeds, and PWM controls to user-space. Content includes discussions of driver-specific fixes, such as a TOCTOU race condition in the ftsteutates driver that could cause crashes or incorrect readings. While the tag is Linux-focused, it may be relevant to Windows users running Linux in virtual machines or dual-boot setups. Topics include kernel patches, driver stability, and sensor accuracy.
