Still needed in 21.02? (R7800 scaling settings)

Installing and Using OpenWrt
1

When I first installed OpenWrt on my 2 R7800 they weren't stable. They crashed/rebooted within a week or so.
I found several posts discussing similar behavior and found a solution by adding the lines below in the local startup script.

> # Ondemand Governor Tweaks
> echo ondemand > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
> echo ondemand > /sys/devices/system/cpu/cpufreq/policy1/scaling_governor
> echo 800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
> echo 800000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq
> echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
> echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
> echo 1000000 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate

21.02 is around the corner (I secretly installed it). Are these lines still necessary in 21.02?

TIA

The most important ones of those have been backported to 21.02 (already in May) into /etc/init.d/cpufreq

See

I think there were some fixes made in the code, but you should probably check in Ipq806x NSS build (Netgear R7800 / TP-Link C2600 / Linksys EA8500)

I only ever used the scaling_min_freq on my C2600s (running as APs) and they've been rock stable,
uptimes over 100 days, the longest passing 300 days, but it's running 07.3 which didn't have the issue the params are addressing.

OK, I going to delete the lines and see what happens.
