bsherman is there a differnce between

@bsherman is there a differnce between kmod for v4l2loopback and our kmods? mainly asking would using kmods directly from rpmfusion circumvent these issues you are trying to solve

bsherman•9/25/23, 7:30 PM

not 100% sure what you mean...

our akmodsakmods repo just pre-builds the akmods from rpmfusion for the specific kernel on the image version we are deploying and stages them so we can later install

BigpodOP•9/25/23, 7:31 PM

hmm, so why could i layer v4l2loopback in past even tho out akmods were already applied

BigpodOP•9/25/23, 7:31 PM

but you are saying that after we make an image users cant apply new ones

bsherman•9/25/23, 7:32 PM

v4l2loopback was the very first kmod added to main images, so I'm not sure when you could have done so

BigpodOP•9/25/23, 7:33 PM

nvidia was the first one ever

BigpodOP•9/25/23, 7:33 PM

i had it in an nvidia image

bsherman•9/25/23, 7:33 PM

true, i was just referring to main, not nvidia

bsherman•9/25/23, 7:33 PM

interesting question.

bsherman•9/25/23, 7:34 PM

I'd have to sift through commits... another side of the problem is the inclusion of kernel-devel packages, i'm not sure if they were part of nvidia way back then

bsherman•9/25/23, 7:35 PM

but, regardless, the problem trying to solve has more to do with simplifiying the overall build process and incidentally makes the main images simpler/better for layering akmods

BigpodOP•9/25/23, 7:36 PM

ok looked at when i had added v4l2 akmod to my image it was mid april so i layered it before that as i was testing if that is enought to enable obs virtual cam(and it was)

bsherman•9/25/23, 7:36 PM

that was not coming across well in the chat discussion

BBigpod ok looked at when i had added v4l2 akmod to my image it was mid april so i layer...

bsherman•9/25/23, 7:36 PM

ok, i'm going to look at nvidia from that time frame, interesting

BigpodOP•9/25/23, 7:36 PM

what does it simplify?

BigpodOP•9/25/23, 7:36 PM

just curious

bsherman•9/25/23, 7:37 PM

did you read my proposal?

akdev•9/25/23, 7:37 PM

the problem with the local layering seems to be that basically we freeze the dev dependencies at the build time and when a user tries to do rpm-ostree install some-akmodrpm-ostree install some-akmod then the kernel version it tries to pull in will be whatever is available in the repos and not what we set at build time

akdev•9/25/23, 7:37 PM

Hence dep conflict

bsherman•9/25/23, 7:38 PM

from proposal

- Reduce complexity of builds and number of images maintained
- Provide a single foundational image for all downstream Universal Blue images/users
- Prevent artificial restrictions on downstream usage

the single foundational image is confused today because of both nokmods and main existing

BigpodOP•9/25/23, 7:39 PM

i didnt even know nokmods image existed so

bsherman•9/25/23, 7:40 PM

yeah, it's getting confusing as we try to make workarounds

bsherman•9/25/23, 7:40 PM

that's part of what i'm trying to address before it gets worse

Aakdev the problem with the local layering seems to be that basically we freeze the dev...

BigpodOP•9/25/23, 7:40 PM

that doesnt seem to be a problem if you update the image daily

bsherman•9/25/23, 7:41 PM

but main with kmods can't be the base for all of ublue today we had to hack a workaround

BBigpod that doesnt seem to be a problem if you update the image daily

akdev•9/25/23, 7:41 PM

It may be a problem depending on which mirrors are hit, time frame of the kernel release and which mirrors have which versions

akdev•9/25/23, 7:41 PM

Basically the same problem we were having of Rpmfusion being out of sync

bsherman•9/25/23, 7:42 PM

eh, it's different, becasue by adding a kmod to main it prevents downstreams from changing kernels

akdev•9/25/23, 7:42 PM

I mean the root cause of why the kmods get that dependency conflict

bsherman•9/25/23, 7:42 PM

Bbsherman eh, it's different, becasue by adding a kmod to main it prevents downstreams fro...

BigpodOP•9/25/23, 7:42 PM

it shouldnt

bsherman•9/25/23, 7:44 PM

i mean

there's a lot of things i think shouldn't work a certain way... i agree with you it should work better but RJ Kyle and I were all certainly stuck on this

Bbsherman i mean 🙂 there's a lot of things i think shouldn't work a certain way... i agre...

BigpodOP•9/25/23, 7:44 PM

better question would have been why

BigpodOP•9/25/23, 7:45 PM

so im asking why now

BigpodOP•9/25/23, 7:46 PM

because i dont see a reason why it wouldnt work

bsherman•9/25/23, 7:47 PM

I am happy for you to find the answer and share. I would appreciate it.

BigpodOP•9/25/23, 7:48 PM

first i would like to know why you think it doesnt work

BigpodOP•9/25/23, 7:48 PM

or point me to discussion of why it doesnt work

akdev•9/25/23, 7:50 PM

It’s linked in the proposal I think

akdev•9/25/23, 7:50 PM

At least in the original ticket it was

Aakdev https://github.com/ublue-os/main/issues/85

BigpodOP•9/25/23, 7:52 PM

i think this was for the original question where i said that i could install akmods in past even if there were akmods present, now we are talking about adding kmod prevents downstream from changing kernel which seems not how it should work if you remove all kmods and kernel you should be able to add new kernel

bsherman•9/25/23, 7:53 PM

I feel like you're asking me to document months of intermittent effort here... not all done by me.

akdev•9/25/23, 7:54 PM

Yeah I think the problem with that is that you need to know what to remove, I think bazzite did that before nokmods existed - you can check their issue tracker

Bbsherman I feel like you're asking me to document months of intermittent effort here... n...

BigpodOP•9/25/23, 7:55 PM

yes becuase you are essentially saying trust me bro, i have a hard time making such a decision without being properly informed

bsherman•9/25/23, 7:55 PM

wow

akdev•9/25/23, 7:55 PM

Asking for such level of documentation seems completely unwarranted - that takes a lot of time to do… Possibly more than making the changes themselves

EyeCantCU•9/25/23, 7:56 PM

@Bigpod it doesn't work. I've confirmed it as well

bsherman•9/25/23, 7:56 PM

I suppose I'm more saying I trust @EyeCantCU and @KyleGospo ... maybe that's an appeal to authority, but they were the ones blocked on asus/surface support and this is related to how we resolved that issue.

Kyle Gospo•9/25/23, 7:59 PM

You can't install akmods on OCI, I tested this with the upstream fedora images

Kyle Gospo•9/25/23, 7:59 PM

It's a limitation

bsherman is there a differnce between
