20:35 <aphirst> Good Evening everyone

20:36 <aphirst> i have some queries about the output of the `bcmstat.sh` tool included with libreelec, which I presume is responsible for some of the system monitoring on rpi boards

20:37 <aphirst> the 3 columns i'm most interested in are "ARM", "Core" and "H264"

20:37 <aphirst> the first and last are pretty self-explanatory - "ARM" seems to report the CPU frequency which tracks nicely with CPU load, and "H264" tracks with the h264 hardware decoding

20:38 <aphirst> but what does "Core" refer to, and how is it being governed? i notice that it peaks at 500Mhz (color-coded in red) during some activity but tends to drop to about 333Mhz and ultimately idle at 250MHz a lot of the time

20:39 <aphirst> i ask this because on a similar rpi4 board i got the same bcmstat.sh tool working but was surprised that this "Core" value stuck at 500Mhz

20:39 <aphirst> I would like to know what power management settings libreelec is using for this specific aspect and set them up on my other boards

20:40 <aphirst> it seems to be this tool: nproc | xargs seq | xargs -n1 -P4 md5sum /dev/zero

20:40 <aphirst> whoops, wrong copypaste

20:40 <aphirst> https://github.com/MilhouseVH/bcmstat

20:50 <aphirst> ah ok, i think this is the frequency of the video core

20:50 <aphirst> something in libreelec sets this up to allow this to scale down whereas on my other setup this hasn't been done

20:51 <aphirst> now i just have to work out what exactly in libreelec is setting this

22:49 <lrusak> are you using the ondemand governor?

23:49 <aphirst> lrusak, hi there!

23:50 <aphirst> i believe ondemand is used by default on the other setup i want to reproduce the behaviour on

23:52 <aphirst> ahh i see what you're getting at

23:52 <aphirst> libreelec is set to powersave

23:52 <aphirst> at least, my idle libreelec rpi4 is

23:53 <aphirst> how is that being set at boot though

23:54 <aphirst> argh, no, hang on

23:54 <aphirst> wrong terminal

23:54 <aphirst> you can tell it's getting late in the day

23:54 <aphirst> my libreelec rpi4 is using ondemand as is the archlinux-arm rpi4 i want to reproduce libreelec's low "Core" clock
