<Hammdist>
hello fellow armbianites. I would like to build armbian for renegade with rt patches. can anyone point me how to start in this endeavor?
<Hammdist>
assume I have read this: https://docs.armbian.com/Developer-Guide_Build-Preparation/ . I need to know: how to find out what kernel version is being attempted to be built by armbian (so I can try to locate a matching patch), where to place the patch and any settings needed to make sure it is picked up
<archetech>
did ya try a pre-built img?
<Hammdist>
are there pre-built with rt? let me check again ...
<Hammdist>
none of the pre-built mention rt, so I assume it is not supported there ...
<DC-IRC>
<lanefu> Correct non of the prebuilt have full rt
<DC-IRC>
<lanefu> Which kernel version do the rt patches need
<Hammdist>
they are generally based on lts versions if I am reading it right
<Hammdist>
so `uname -r` on stock kernel reports 6.1.30-rockchip64
<Hammdist>
there is corresponding patch 6.1-rt
<Hammdist>
I guess the first step would be to try to get hold of the exact kernel sources armbian is using and try to manually apply the patch on them to see if it applies cleanly

<Hammdist>
so armbian build tool has this directory: build/patch/kernel/rockchip64-current ... it seems to be populated with a bunch of existing patches. would be nice if I could add a patch here but I'm not sure how to get it included
<Hammdist>
does it just grab everything in that directory?

<steev_> yes
<DC-IRC>
<steev_> but, 6.5 complete changes the way audio works, and breaks it for 6.5, i haven't yet gone through to backport the changes to 6.4 (and upstream has no plans to)
<DC-IRC>
<steev_> but, 6.4 complete changes the way audio works, and breaks it for 6.5, i haven't yet gone through to backport the changes to 6.4 (and upstream has no plans to)

<steev_> but, 6.5 5complete changes the way audio works, and breaks it for 6.4 i haven't yet gone through to backport the changes to 6.4 (and upstream has no plans to)
<Hammdist>
does that impact me? I'm sticking with 6.1 for now ...
<DC-IRC>
<steev_> sorry, that was meant as a reply to questions about the x13s
<Hammdist>
ah sorry I'm probably not seeing that convo from libera .. my bad
<DC-IRC>
<steev_> your question re: patches, user patches should go in the userpatches directory, i believe (it has been a long while since i've looked at the build system, sorry)
<Hammdist>
well putting it in the patch/ directory directly seems to work also. but trouble is now, that the patch does not apply cleanly. it mostly goes through but there is a failed hunk. will see if anything can be done about it
<DC-IRC>
<steev_> fix it 🙂
<DC-IRC>
<Tonymac32> yeah that's the cycle pretty much, compile, check, fix. I would assume one of our other patches is overlapping
<DC-IRC>
<c0rnelius77> I seriously doubt Armbian patches are effecting RT patches. RT patches generally depend on the revision of the kernel they are being applied too. If he could specify the exact rev of the kernel he wanted to use, I'm sure the patch would apply.
<Hammdist>
yeah it is a slight version mismatch `HEAD is now at d2a6dc4ea Linux 6.1.42` vs patch intended for 6.1.38
<Hammdist>
compile.sh doesn't take kernel version in any shape or form does it?
archetech has quit [Quit: Konversation terminated!]
<DC-IRC>
<steev_> you could tell it to use a specific kernel checkout, i think, or could at one point
<DC-IRC>
<steev_> okay for x13s stuff -i just pushed out a breaking 6.4 kernel - breaking in that, if you don't have the corresponding userspace changes, you'll get "dummy output" for audio
<DC-IRC>
<steev_> copying from the irc channel because i'm too lazy to type it up myself

<DC-IRC>
<steev_> ``` Dependencies:
<DC-IRC>
<steev_> - latest topology file installed in new location:
<DC-IRC>
<steev_> - Make sure to turn down volume before testing as not updating all components in lock step could lead to volume levels that can potentially damage ears and speakers!```
<Hammdist>
ah I managed to get it to pull 6.1.38 and the patch applied. it's now compiling the kernel, on `nproc` cores, too which is nice
<Hammdist>
for anyone who might be interested, I made this edit to get it to pull a specific kernel version: config/sources/families/include/rockchip64_common.inc:135:KERNELBRANCH="tag:v6.1.38"
<Hammdist>
kernel compiled but there is a subsequent problem with the naming of the image file
<Hammdist>
I think I have a handle on it

well I booted into rt kernel "successfully" but I can't work the cyclictest program to see how realtime it even is. I get "Probably missing capabilities, either run as root or increase RLIMIT_RTPRIO limits." ... but I am running as root of course
<DC-IRC>
<jkent.net> Do you need to enable some kernel configuration switches?
<DC-IRC>
<jkent.net> I've never used RT, so i'm not sure
<Hammdist>
I did enable a few knobs in the kernel config. could be that I missed something
<DC-IRC>
<Tonymac32> CONFIG_PREEMPT_RT_FULL needs to be set it looks like
<Hammdist>
I think that's just PREEMPT_RT=y which is set

<foutkassir> Hello everyone, hope you are doing great!
<DC-IRC>
<foutkassir> just one qq question I started to use armbian on my orange pi 3 lts and I did discover that sysstat is filling my var/log which is 47Mb size
<DC-IRC>
<foutkassir> `42M ./sysstat`
<DC-IRC>
<foutkassir> tried to login as su and clean it, after a reboot I can see that it's back with 98% usage and seems rm didn't help much. Moreover I did ensure that service is disabled and stopped.
<DC-IRC>
<foutkassir> any further suggestions?
<DC-IRC>
<foutkassir> normally shouldn't it do rotation out of the box? or there is a particular settings I need to look at
<DC-IRC>
<lanefu> @foutkassir `/usr/lib/armbian/armbian-truncate-logs` is the script that does the housekeeping
<DC-IRC>
<foutkassir> thanks for your quick response @lanefu , looking into it `working only when armbian-ramlog is enabled` this would mean that in my case armbian-ramlog isn't enabled ?
<DC-IRC>
<foutkassir> I don't have it installed
<DC-IRC>
<foutkassir> which mean the var/log is getting saturated and not truncate
<DC-IRC>
<lanefu> i'd suggest lookiung at `/etc/sysstat/sysstat`
<DC-IRC>
<lanefu> i'd suggest looking at `/etc/sysstat/sysstat`
<DC-IRC>
<foutkassir> well I guess enabling armbian-ramlog would better help then messing with sysstat. do you have any idea on how to get it ?
<DC-IRC>
<lanefu> go look at the config file before drawing conclusions
<DC-IRC>
<foutkassir> sure thanks
<DC-IRC>
<foutkassir> I don't see anything that would do rotation. the issue is that I do have the service for sysstat disabled and I keep on seeing the storage saturated
<DC-IRC>
<foutkassir> ```
<DC-IRC>
<foutkassir> ○ sysstat.service - Resets System Activity Logs
<DC-IRC>
<foutkassir> I do have sysstat already disabled do you feel it's comming from armbian-ramlog?
<DC-IRC>
<foutkassir> I do have sysstat already disabled do you feel it's coming from armbian-ramlog?
<DC-IRC>
<foutkassir> now by just rm -rf /var/log/sysslog it would empty it right?
<DC-IRC>
<tenkawa42> @lanefu isn't there /etc/default settings to change armbian-ramlog sizes/etc?

is ~55C too high a temp for a renegade (should I add heatsink?) or is it fine?
<Herc>
55°C sounds ok for me
<Hammdist>
the datasheet only lists maximum ambient temperature ...
<Herc>
be alarmed if >80°C maybe
<Hammdist>
seems like a misprint in the datasheet they probably just mean operating temperature and the limit is 80C
<Hammdist>
does anyone know what the units are for cyclictest --smp -p98 -m? I'm getting values of few hundred for a short while then eventually it jumps to ~30,000
<Hammdist>
ah they are us apparently
<Hammdist>
so 30ms. that's useless ...
<DC-IRC>
<jason123santa> I recommend getting a heatsink just to be safe
<Herc>
a heatsink wont help at all (if not combined with a fan)
<Herc>
AND what is so bad @ 55°C?
<Herc>
silicon chips will feel healthy
zeemate has quit [Ping timeout: 264 seconds]
<DC-IRC>
<jason123santa> the thing you want to prevent is it getting so hot when its at more usage
<DC-IRC>
<c0rnelius77> The renegade is like all other 3328's. if they get to hot they stall. I would atleast put a heatsink on it.
