I am running some performance tests on the HiKey board and thus I wanted to disable the frequency scaling mechanism; I set the scaling governor to “userspace”, and then set the CPU cores clock to 1.2GHz.
I discovered that when the thermal sensors detect a temperature over 50 Celsius degrees the frequency is automatically reset to the lowest.
Using a fan seems not to be enough for sustained computation at the maximum frequency.
Is it safe / possible to increase the 50 degree threshold?
Which is the maximum operating temperature for the SoC?
Thanks and Best Regards,
