h3consumption recover 4 cores on opi0 not working bullet-proof

[peter12]

Hi there, 

I have problem with recovering "sudo h3consumption -m 1200 -c 4" on Orange Pi Zero, where it activates just 2 cores. No idea why. When I used "sudo h3consumption -m 900 -c 1" it worked fine, but now, when I am trying to recover all 4 cores it activates just 2 cores.
Which files h3consumption changes? (so I will be able to backup them with clean install and the restore them once needed to recover settings for all 4 cores).

 

And I found out, that with "sudo armbianmonitor -m" it shows CPU changes 900Mhz, 1018Mhz (dont remember exact values) but now it just shows 480

 

P.S. I made backups of these files:
sudo cp /etc/backup_2017_05_21_rc.local /etc/rc.local
sudo cp /boot/backup_2017_05_21_bin_orangepizero.bin /boot/bin/orangepizero.bin
sudo cp /boot/backup_2017_05_21_bin_orangepizero.bin /boot/script.bin

 

UPDATE: after few restarts and combination of 

echo 1 >/sys/devices/system/cpu/cpu2/online;
echo 1 >/sys/devices/system/cpu/cpu3/online; in rc.local now 4 cores work again. Strange behaviour.

Hi Peter12,

 

I have a NanopiNeo and experienced the same problem.

 

I changed the h3consumption script.

Somwhere in the script in states:

 

Old:

        # Active CPU cores
        case ${CPUCores} in
                ""|4)
                        # enable corekeeper
                        sed -i -e 's/^corekeeper_enabled\ =\ 0/corekeeper_enabled = 1/g' "${FexSettings}"
                        ;;
                3)
                        # disable corekeeper and 1 core in /etc/rc.local
                        sed -i -e 's/^corekeeper_enabled\ =\ 1/corekeeper_enabled = 0/g' "${FexSettings}"
                        echo "echo 0 >/sys/devices/system/cpu/cpu\3/online" >>"${RCLocalContents}"
                        ;;
                2)
                        # disable corekeeper and 2 cores in /etc/rc.local
                        sed -i -e 's/^corekeeper_enabled\ =\ 1/corekeeper_enabled = 0/g' "${FexSettings}"
                        echo "for i in 3 2; do echo 0 >/sys/devices/system/cpu/cpu\${i}/online; done" >>"${RCLocalContents}"
                        ;;
                1)
                        # disable corekeeper and 3 cores in /etc/rc.local
                        sed -i -e 's/^corekeeper_enabled\ =\ 1/corekeeper_enabled = 0/g' "${FexSettings}"
                        echo "for i in 3 2 1; do echo 0 >/sys/devices/system/cpu/cpu\${i}/online; done" >>"${RCLocalContents}"
                        ;;
                *)

 

 

I added the line:
                        echo "" >>"${RCLocalContents}"

and now it looks like this:
New:

        # Active CPU cores
        case ${CPUCores} in
                ""|4)
                        # enable corekeeper
                        sed -i -e 's/^corekeeper_enabled\ =\ 0/corekeeper_enabled = 1/g' "${FexSettings}"
                        echo "" >>"${RCLocalContents}"
                        ;;
                3)
                        # disable corekeeper and 1 core in /etc/rc.local
                        sed -i -e 's/^corekeeper_enabled\ =\ 1/corekeeper_enabled = 0/g' "${FexSettings}"
                        echo "echo 0 >/sys/devices/system/cpu/cpu\3/online" >>"${RCLocalContents}"
                        ;;
                2)
                        # disable corekeeper and 2 cores in /etc/rc.local
                        sed -i -e 's/^corekeeper_enabled\ =\ 1/corekeeper_enabled = 0/g' "${FexSettings}"
                        echo "for i in 3 2; do echo 0 >/sys/devices/system/cpu/cpu\${i}/online; done" >>"${RCLocalContents}"
                        ;;
                1)
                        # disable corekeeper and 3 cores in /etc/rc.local
                        sed -i -e 's/^corekeeper_enabled\ =\ 1/corekeeper_enabled = 0/g' "${FexSettings}"
                        echo "for i in 3 2 1; do echo 0 >/sys/devices/system/cpu/cpu\${i}/online; done" >>"${RCLocalContents}"
                        ;;
                *)

 

Now it works just fine.

Hi Peter12

 

When using armbianmonitor -m the first value is the cpu under load. After that it shows the actual cpu speed.

 

On my NanopiNeo it looks like this:

 

root@nanopineo:/boot# armbianmonitor -m
Stop monitoring using [ctrl]-[c]
Time        CPU    load %cpu %sys %usr %nice %io %irq   CPU
23:47:14:  912MHz  0.00   0%   0%   0%   0%   0%   0%   38°C
23:47:19:  240MHz  0.00   0%   0%   0%   0%   0%   0%   38°C

 

The 912MHz is the max CPU speed for my Pi

The 240MHz is the CPU speed in idle.

 

When the CPU load is increased the CPU speed is automaticly increased.
