Is there anything how you determine in software that the machine turns too hot because of insufficient cooling and for that reason reduces its performance?<span class=""><br>

There’s always the possibility that Raspbian uses a custom driver which isn’t yet upstreamed. I was never interested in these two numbers, so I can’t help, sorry.<br>

Hello,<br>
<br>
can you please help with magic lines to learn about the<br>
temperature of the RPi3 and at what frequency the CPU is operating?<br>
<br>
This is apparently different from what Raspbian makes us expect. I<br>
am running your 20180108 buster image, i.e.<br>
CONFIG_THERMAL=y<br>
CONFIG_HWMON=y<br>
CONFIG_THERMAL_HWMON=y<br>

# find /sys -maxdepth 11 -name \*_input -o -name temp<br>

# cat /sys/devices/virtual/thermal/t<wbr>hermal_zone0/temp<br>
cat: /sys/devices/virtual/thermal/t<wbr>hermal_zone0/temp: Invalid argument<br>
# ls /sys/devices/virtual/thermal/t<wbr>hermal_zone0/<br>
