<tlwoerner>
wow, i hope not. i've got about a dozen of these guys deployed, some in awkward places
<dsimic>
tlwoerner: it depends on the CPU workload they're handling
<dsimic>
e.g. bursty CPU load might go just fine even with no thermal configuration in place
<dsimic>
but it's too risky anyway
<tlwoerner>
agreed. mine are mostly monitoring sensors, ssh connections, getting updates, nothing too strenuous
<dsimic>
anyway, it would be much better to have the thermal configuration implemented, tested, and upstreamed
<tlwoerner>
perhaps that is something i could take a look at, do you recommend an example i could follow?
<dsimic>
pretty much any Rockchip board is a good example
<dsimic>
however, I could ask Radxa to send me a ROCK Pi S0, and I'd be willing to get that implemented and tested
<Kwiboo>
dsimic, tlwoerner: I do not think there is that big of a thermal issue for rk3308b, the soc is rated for up to 1.3 ghz and max opp in dtsi is 1 ghz, and the soc does not seem to get that hot, however there is also a rk3308bs variant that has different voltage and cpu rate limits
<tlwoerner>
in any case it would be nice to have the infrastructure in place to be able to monitor its temperature
<tlwoerner>
(as i can with the others)
<dsimic>
hmm, the user manual says it goes up to 1.0 GHz, whish the DT confirms?
<dsimic>
s/whish/which/
<dsimic>
while the vendor kernel goes up to 1.3 Ghz
<dsimic>
the BS variant goes up to 1.1 GHz :)
<dsimic>
anyway, it's much better to get it done right
<tlwoerner>
none of my cpus seem to currently ever use the slowest speed
<dsimic>
hmm, that's a bit strange
<dsimic>
alright, I'll ask Radxa for the S0 and some more hardware for another nice upstream endeavor :)
<tlwoerner>
nice
<dsimic>
just keep an eye on rockchip-linux
<dsimic>
I hope you'll be willing to test the patches :)
<tlwoerner>
absolutely! please ping me when you post them
<dsimic>
let me paste a few lines here, for future reference... pastebins can go away...

it's really suspicious that the lowest CPU OPP isn't used at all

actually, can you give me your full name and email address, and I'll include your Reported-by tag?
<tlwoerner>
coincidentally i updated my fleet last night, so the uptime is only about 12 hours
<tlwoerner>
thanks for the tag! (i appreciate it)
<dsimic>
still, 12 hours is fairly long
<dsimic>
sure
<dsimic>
thank you for reporting this issue :)
<tlwoerner>
so far i have about a dozen rockchip-based devices around the farm (and many more planned!) monitoring bunches of sensors
<tlwoerner>
everything built with yocto master, upstream kernels and bootloaders
<tlwoerner>
full A/B updates with rauc
<tlwoerner>
i'm starting to implement the sensor monitoring and dashboard phase
<tlwoerner>
starting with mqtt, but will be moving to kafka
<tlwoerner>
i was only recording the actual sensors so far, but then noticed that most are also reporing cpu/gpu/soc temperatures and thought: why not?
<tlwoerner>
then noticed my rk3308
<tlwoerner>
my server is a rock-pi-4a running the penta sata hat
<dsimic>
very nice!
<tlwoerner>
i've been lucky enough to have radxa send me some free hardware too, my backup server is a rock-5a they sent me
<tlwoerner>
but i don't have a penta sata hat on that one (yet)
<dsimic>
that's some rather serious operation you're running :)
<tlwoerner>
i also have a board farm (as opposed to... and actual farm) with one of everything i'm using in there
<tlwoerner>
so if you've got stuff to test... :-)
<tlwoerner>
i'm all setup for easy patching, building, deploying, testing

I've been disconnected for the last 10 minutes or so, have I lost some messages?
<tlwoerner>
i can read my spi, i2c, and w1 sensors, so it works for me

i replied with my tag about an hour ago

<dsimic>
thanks for replying :)
<tlwoerner>
interesting, i'm not seeing it on lore either
<tlwoerner>
i'll resend tomorrow if it doesn't show up
<tlwoerner>
np
<dsimic>
I think it should appear rather soon
<dsimic>
but sometimes delivery takes multiple hours

dsimic: I have been running stress with performance gov for ~2h on a rk3308b rock-pi-s board and soc temp seem to top out at ~50 deg c with ambient temp ~21 deg, vendor kernel use 115 deg as critical temp, similar to px30, so probably not that big of a risk of damage with current opps ;-)
