Installing drivers with a read-only file system

I'm trying to install a driver for my wifi dongle, but when using the method I saw online I'm getting a read-only file system error. I understand why the system is read-only, but is there a way I could modify this command to get the driver working within the limitation of a read-only file system? The command is question is: sudo make dkms_install and here's where I'm getting the tips on how to install the driver (I'm obviously swapping all instances of apt with rpm-ostree) https://community.tp-link.com/en/home/forum/topic/184118

try just use-broadcom-wl

resulted in a gray screen on boot

Please don't enable Broadcom WL as this isn't even a Broadcom device whatsoever. You have a Realtek 8812au. To get it working someone would have to put together a kmod for it

llakalaOP•13mo ago

I found a kmod on GitHub, what's the proper commands to compile it into an rpm file? when I tried I got some vague error messages

dnkmmr•13mo ago

thank ostree for giving us rollbacks

EyeCantCU•13mo ago

Can you link me to the repo? I wasn't able to find anything packaged for Fedora specifically yesterday

readme was in Russian and a few years old but seems to say fedora

EyeCantCU•13mo ago

Oh wow. From over 6 years ago. Almost guarantee its incompatible with the current kernel

llakalaOP•13mo ago

damn gotcha

llakalaOP•13mo ago

https://github.com/aircrack-ng/rtl8812au there's this one, but it's not as a kmod

https://openwrt.org/packages/pkgdata/kmod-rtl8812au-ct and this seems newer with a kmod

package: kmod-rtl8812au-ct

but might not be for Fedora

Is it ok to continue this conversation? I am having the same issue. I built an RPM and installed it with rpm-ostree successfully, but It didn't autoload for the device. I'm guessing I'm missing a udev rule or installing it to the wrong location. Manually inserting the kernel module (from the rpm installed location) does get the wifi adapter going. I am using an rtl8814au, but there is a similar repo for the rtl8812au that I think could be packaged in the same way. It isn't the cleanest rpm spec file, I've got some hard-coded versions in the %files for example that would need updated if it were to become part of a build process.

If you can PR it to ublue-os/akmods it can easily be included

tulip•11mo ago

That would be pretty awesome! Please consider doing that @zerochill

zerochill•11mo ago

I'm up for this. I took a look at the akmods repo in github, but couldn't follow how the source code for each repo is actually getting pulled down. I know the way I was doing it by cloning during the prep step isn't used frequently. I followed the ublue-os/akmods repo over to the copr repo and looked for the assets for build-kmod-wl.sh, but didn't see where those rpms would be coming from, so I looked at the gasket kmod in the copr build and found that is is built from https://github.com/KyleGospo/gasket-dkms.git, but I still don't understand what pulls that in? I'm not that familiar with copr or packaging for fedora, so sorry about my ignorance here.

Kyle Gospo•11mo ago

That one is built in my repo, in your case maybe PR your spec to ublue-os/packages I'll build it in our akmods copr repo and then you can use it in a PR to ublue-os/akmods

zerochill•11mo ago

Ok great, I'll do that and put in a PR on both of those repos. Thanks! I finally got some time to work on this again. I got an akmods packages building in a personal copr and was able to install it into a container using the akmods command. I have to step away again, but I'll figure out installing it to my host system and make sure it works and then get a PR up for the repos. I'll package up the RTL8812 drivers after I make sure the RTL8814au is working, since I can't test the RTL8812 myself.

zerochill•11mo ago

Ok, I'm pretty sure that this is working so I made a PR, but I'm pretty new to akmods, so definitely give me a shout if something looks off. https://github.com/ublue-os/packages/pull/9

It’s ok to bring this back? How can I make this work on my machine?
