CPU governor and core work CM13

[sergiopoverony]

I now test my device under cpu-z
All core work AllTime. May be is governor problem?

[cmorlok]

This is the default behavior in Android. There are several custom governors which disable cores, but there isn't an official one.

@cmorlok default minfreq is 800mhz - meybe downlow to 200? this is save battery

[sergiopoverony]

@cmorlok @Kra1o5 @eloimuns maybe compile kernel wich use hotplug governor - this is for multicore devices - more good? Need for powersave and good work device/
Please from here/ as example https://android.googlesource.com/kernel/mediatek/+/android-mediatek-sprout-3.4-kitkat-mr2/drivers/cpufreq/cpufreq_hotplug.c

Hi @sergiopoverony ,

Not much sense since we have perfd & core_ctl options.

[sergiopoverony]

i see in other cm fw cpu tune settings. we can see it?

[Kra1o5]

This option dissapear some time ago in cm.

[sergiopoverony]

It's sad that you can not control the frequencies and governors

[sergiopoverony]

@cmorlok @Kra1o5 @eloimuns Please check is it
I check on Stoсk FW and CM 13.
In Stoсk kernel work is fine. i see stopped cores = save my battery. In CM13 not see it.

[cmorlok]

We have activeated core_ctl for testing purposes. It doesn't hurt, but it doesn't improve battery life either. It will be included in one of the upcoming nightlies.

@cmorlok Good news. i ready and prepare )))

Can you try again with the 20161020 nightly? The changes have been merged.

[sergiopoverony]

@stucki i check tomorrow. now deep night in Russia )

[sergiopoverony]

@stucki cant donwload FW/... ~99% and no more. I reboot device. Clean memory and etc. No more. Not Download!

[stucki]

Hmm, download works fine for me. You may try to download it via https://get.cm/ manually. Also make sure to check the sha1 checksum.

[sergiopoverony]

@sticki got it. Is fine. Ctl work. Now need 2-3 days for test.

[sergiopoverony]

@sticki Good work. uptime ~+35%
