From forum: https://dietpi.com/phpbb/viewtopic.php?f=11&t=5580
Derived from Ayufan script: https://github.com/ayufan-rock64/linux-package/blob/master/root/usr/local/sbin/rock64_fix_performance.sh
Throws some errors on new ARMbian (much newer kernel version) based image but seems to significantly increase certain performance aspects.
Requires someone with Rock64 (or as well test on RockPro64) board an willingness to test each step, in case find the new/correct kernel API file, and run performance tests.

ARMbian offers a script to enable full GPU acceleration on Rock64: https://forum.armbian.com/topic/9310-rk3328-media-script-rock64-renegade/
Do we use this as well, or should we?
Also interesting to know: http://opensource.rock-chips.com/wiki_Status_Matrix

I have a rock64 4Gb. Do you want help to test anything on this hardware ?

If you find time, the following would be interesting to get a picture of the default values that are affected by Ayufans performance script:
- Current GPU DevFreq governors:
ls -l /sys/class/devfreq/
cat /sys/class/devfreq/ff9a0000.gpu/governor # should return error as ROCKPro64 only
cat /sys/class/devfreq/ff300000.gpu/governor
cat /sys/class/devfreq/dmc/governor
- Current SMP affinities:
cat /proc/interrupts
while read -r irq cpu0 cpu1 cpu2 cpu3
do
[[ $icq =~ ahci|echi|ohci|xchi|eth|'0000:01:' ]] && echo -n "$icq = " && cat /proc/irq/${irq%:}/smp_affinity
done < /proc/interrupts
- Onboard Ethernet RPS:
cat /sys/class/net/eth0/queues/rx-0/rps_cpus
cat /proc/sys/net/core/rps_sock_flow_entries
cat /sys/class/net/eth0/queues/rx-0/rps_flow_cnt
- I take out CPU governor since we already cover this with
dietpi-config/dietpi-set_cpu.

I take out CPU governor since we already cover this with dietpi-config/dietpi-set_cpu.
@MichaIng anything else needed? Do you need DietPi test runs? I need to find a spare SD/USB card so not sure when I could do this but in preparation for that do you have an image/steps that need to be tested?
I suspect @Pain-Patate will get same results with the 4Gb model but be good to get that confirmed.

Many thanks for sharing this info.
What I get from it is that /sys/class/devfreq/ seems to exist only on legacy kernel (4.4) images, so nothing to do our end on mainline kernel.
Ethernet RPS is disabled by default but manually set on Ayufan and OMV images. Actually interesting one, I have to read a bid into it to find out in which cases it is really a network performance benefit: https://www.suse.com/support/kb/doc/?id=000018430
Probably we can build up a simple test scenario and invite users to test it with different devices, e.g. by copying a large file (or large amount of small files) via NFS and/or SFTP/SCP, then measuring CPU usage on all cores and the time required.
For SMP affinities we could follow a certain logic to separate e.g. local drive I/O, GPU tasks, audio and network interfaces, although e.g. in case of audio and drives they may both be on USB and hence difficult to identify/differentiate on a generic basis. By default SMP affinities seem to allow all CPUs for all IRQs which results (at least on non-x86 systems without SMP balancer) in CPU0 being used for all of them. But first we'd need to check if setting the affinity is actually possible. E.g. I tested on my 4-core RPi where all interrupts are handled by CPU0 but it is not possible to change the affinities:
2020-06-11 23:32:40 root@micha:~# l /proc/irq/56/smp_affinity
-rw-r--r-- 1 root root 0 Jun 11 23:32 /proc/irq/56/smp_affinity
2020-06-11 23:32:49 root@micha:~# printf 2 > /proc/irq/56/smp_affinity
bash: printf: write error: Input/output error
I was searching the web a bid and indeed this does not seem to be uncommon based on kernel I guess.
Do you need DietPi test runs?
Yes basically the output on a board with Armbian 5.X mainline kernel would be great, either our current ROCK64 beta image or: https://www.armbian.com/rock64/
MichaIng
on 11 Jun 2020
Sorry, i'm a noob.
You want tests on Armbian buster with this script installed ?
Pain-Patate
on 13 Jun 2020
Either Armbian Buster with Linux 5.X kernel or simply our own image. The media script does not play a role since it deals with GPU acceleration only, which is not part of this issue or Ayufans performance script.
GPU acceleration for ROCK64 is discussed here: #1794
The Armbian community media script does not work well with Debian Buster AFAIK due to X11 version incompatibilities, however it could be tested as well. So to get this running we'd need to compile/create an own aarch64 build of libMali.so for ROCK64 since there is none available from any source (I found) compatible with Debian Buster aarch64.
