The kernel module is failing to build on the latest mainline kernel (6.6-rc5). Below is the output from executing make:

The same output is produced if using dkms to build the module. I have uninstalled and reinstalled both the linux-mainline and linux-mainline-headers packages; however, the result is always the same.
This module was building and working fine on mainline kernel 6.3. After upgrading to mainline kernel 6.4 the module has failed to build.
I am currently using the kernel module for kernel 6.5.6 without issues.
It also fails on 6.6-rc1

Kernel 6.6 was release and will arrive in Fedora in about 2 weeks and probably earlier in Arch. Any update on this?
I'm just here waiting for the response from the DisplayLink maintainers saying that Arch/Nix/Fedora is not a supported distribution.
@cedricroijakkers i do not believe that beeing passive agressive will convince the team to change the supported distribution(s). And within the last two years using it they were fast in adapt to new kernels long before they're used in Ubuntu, some versions never were.

Besides that doesnt even matter as this is the kernel module that wont compile on ubuntu as well.

It appears the header file doesnt expose it anymore
No diea what I broke with this but my journal does not get flushed and all 3 screens are working fine again.

Tried applying this patch. The module builds with the patch, but no displays are detected.
This PR https://github.com/DisplayLink/evdi/pull/436 has fixed the issue for me. It's now working on Arch Linux using DisplayLink 5.8, the devel branch of this repo i.e the evdi-git package, and kernel 6.6.1. The maintainers only need to create a new release, or you can build the module straight from git.

Sorry I'm late to respond. The metnioned PR is basically exactly the same implementation. It just added some compiler flags to allow backwards compatibility.
I tested it on about 20 devices running either EOS, Fedora or Ubuntu. I had some issues with upgrading from 1.12.0 in the past maybe that one happened here again.
You can try applying the patch of the PR as well. If you're on Fedora 37/38/39 I can provide you a rpm package if you want to

At this point I'm kind of puzzled what DocMAX and I did wrong yesterday. The latest devel branch does also build but actually functions correctly.
@Kevinjil I did have some funkyness too, a restart of the displaylink service or a reboot did the trick however.
Once loaded, evdi will stay in the kernel until a reboot. Just a hunch, but if you've had an earlier version of evdi loaded, the displaylink driver will detect the discrepancy and refuse serving the displays.
i deleted the dkms evdi folder and recompiled the module with no errors. but doesn't work with 6.6. worked on 6.5 though. with "modprobe udl" and restarting displaylink.service the screens have been detected now. so i will put udl to my /etc/modules-load.d folder.
hmm, no, that wasn't the solution. no idea why the displays are detected randomly. with this log no displays in xfce:

The moment it worked there was:
evdi: [I] Evdi platform_device create
But no idea how i did it.
I also get the following error on 6.6.1-arch1-1 when doing dkms install --no-depmod evdi/1.14.1 -k 6.6.1-arch1-1 --verbose. Did anybody resolve this issue?

@mrscottie or one of the maintainers @displaylink-emajewsk @displaylink-dkurek @displaylink-mlukaszek: This issue can be closed, it has been resolved. Building from the git repo works now, possibly you need to create a new release to finalise it.

Just wanted to chime in - I'm on Fedora 38 with kernel 6.6.2-101.fc38.x86_64 - the current released version upstream for the displaylink-rpm stopped working for me but this RPM from the fork fixed the issue

Great to hear. It's exactly as this ticket mentions, a more recent evdi is required. ( https://github.com/SimonSchwendele/displaylink-rpm/blob/master/evdiFix660.diff )
The patch shouldn't be needed anymore but evdi didn't create a new tag yet ( which in return will be used in the next release of displaylink-rpm )
Hi @Crashdummyy, I am on fedora 39 (Linux 6.6.2-201.fc39.x86_64) and having the same issue as everybody here, and when I tried running your patched rpm, it displayed an error saying it was conflicting with the previous packages. I understand I need to remove the previous packages, but I am not exactly versed in how I can achieve that... any chance you could help me out and tell me how I can remove/clean the previous installation so I can install your version?
Thank you very much!

sudo dnf autoremove displaylink
Maybe thats not enough because the uninstaller might not work that great.
So you could check which versions are installed and kill them in dkms manually.
sudo dkms remove evdi/<version> -a
Afterwards you can remove the loaded ones just to be safe:
sudo rm -rf /var/lib/dkms/evdi
That way youre pretty much clean again. Now you can just reinstall the new version using the provided rpm.
I'm currently on 6.7-RC4 where it still works so I guess you'll be fine

Finally I got it back on Fedora 39! Thank you @Crashdummyy.
A step-by-step list of what I did, in case it is useful for somebody:
sudo dnf install fedora-packager rpmdevtools
sudo dnf install libdrm-devel glibc-devel.i686
git clone https://github.com/SimonSchwendele/displaylink-rpm
cd displaylink-rpm
make
sudo dnf autoremove displaylink
sudo dkms remove evdi/<version> -a
sudo rm -rf /var/lib/dkms/evdi
sudo dnf install x86_64/displaylink-1.14.1-*.rpm
After the last command my external displays immediately came back to life.
