devices/system/cpu/cpufreq/ is empty on 4.19.73-ti-rt-r29

[rvega]

I'm using this repo to compile the kernel version mentioned in the title for a beaglebone green.

I suspect that the cpu frequency is set to a low value because my app is consuming a lot more cpu than before, when I was running 4.4.x-bone-rt.

The directory /sys/devices/system/cpu/cpufreq is empty so I don't know how to verify or set the cpu frequency.

Below are the relevant options from kernel defconfig.

Perhaps I am missing some kernel configs?

dmesg does not show any message regarding cpufreq.

Please help. How can I make sure my cpu is running at full freq?

@rvega the kernel default support that.. figure out what you changed..

debian@test-bbb-5:~$ uname -r
4.19.79-ti-rt-r30
debian@test-bbb-5:~$ sudo cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq

Thanks for checking.
