I have updated our Yocto build for the Colibri T30 to use kernel version 6.1… it took quite a bit of work to do that based on your BSP v 2.8.8 (mostly because some of classes didn’t want to compile the newer kernel versions) but we wanted long term support of existing T30 devices.
Upon loading the OS, we get a few errors from the cpufreq driver
[ 3.045827] tegra20-cpufreq tegra20-cpufreq: operating points not found
[ 3.052705] tegra20-cpufreq tegra20-cpufreq: please update your device tree
do you know what exactly the operating points in this case would be? Do we get dynamic scaling of the
[ 18.409506] tegra30-tsensor 70014000.tsensor: calibration: 12323 10245 90 24 ATE ver: 40 SoC rev: 3
[ 18.567999] tegra30-tsensor 70014000.tsensor: ch0: PMC emergency shutdown trip set to 90C
I am kind of confused on what the situation with cpufreq is in the new kernel. Can I just update the device tree with the OPPs and get dynamic frequency scaling? Or do I need to apply these patches
@marcel.tx can you help us out here? What do I need to do to get the dynamic frequency scaling goodness?
