Odroid Go Advance (OGA) CPU overclocking

[maxromanovsky]

Hello!
Newbie question.
First of all, thank you for an amazing distro!

Second, the question
How can I overclock the Odroid Go Advance (OGA) (i.e. increase CPU frequency)?
I've followed the official Odroid guide: https://wiki.odroid.com/odroid_go_advance/application_note/overclock

I've updated SD card file boot.ini on partition recalbox with the following:

odroidgo2-uboot-config

########################################################################
# Changes made to this are overwritten every time there's a new upgrade
########################################################################        

[...]

# Boot Arguments
setenv bootargs "label=RECALBOX rootwait net.ifnames=0 fbcon=rotate:3 console=/dev/ttyFIQ0 quiet vt.global_cursor_default=0 consoleblank=0 ${joystick_config} mitigations=off"
setenv bootargs ${bootargs} max_cpufreq=1416

[...]

Then, I've booted up and checked via SSH that the changes are indeed in /boot/boot.ini, however they didn't seem to have any effect:

# uname -a
Linux RECALBOX 4.4.189 #1 SMP Sat Jan 29 21:27:11 CET 2022 aarch64 GNU/Linux

# cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies
1008000 1200000 1248000 1296000

And dmesg didn't shot that it was added to the line.

I've also tried putting it all into a single line like this:

setenv bootargs "label=RECALBOX rootwait net.ifnames=0 fbcon=rotate:3 console=/dev/ttyFIQ0 quiet vt.global_cursor_default=0 consoleblank=0 ${joystick_config} mitigations=off max_cpufreq=1416"

After that it appear on dmesg, but no actual change of frequency happened (available frequencie list was the same as before):

# dmesg | grep freq

Thanks in advance for your help

@maxromanovsky Isn't there an overclocking option in the menu like there is on the Raspberry Pi?
