Issues running on Fedora 36 #6

System: Fedora Workstation Edition 36 Device: Surface Pro 7+

Is there a guide for building ithc-linux on Fedora 36? I tried to build but got these error messages:

[pairman@fedora ithc-linux]$ sudo make && sudo make install
[sudo] password for pairman: 
mkdir -p build

Thanks in advance.

This was an issue with the Fedora Surface kernel. It's been fixed now, so it should work once a kernel update is published at: https://github.com/linux-surface/linux-surface/releases

You could also use the normal non-Surface kernel to test ithc.

I cloned again and build failed with the same output.

I'm using the latest build artifact of kernel-surface in github actions of https://github.com/linux-surface/linux-surface. I think it has changed according to the issue you mentioned. But still failed.

Pairman commented 2 years ago

Build succeeded on official linux kernel. But it seems the driver isn't working after rebooting even if I added the intremap=nosid parameter. I'm using Surface Pro 7+.

does secure boot enabled? maybe that is related to the problem

quo commented 2 years ago

Key was rejected by service

Yeah, that looks like a Secure Boot problem. Please remove the module (sudo rm /lib/modules/*/extra/ithc.ko; sudo depmod -a) and try the DKMS installation instead. You can also try to disable Secure Boot. Otherwise, you may have better luck asking on the Fedora support forums.

Thanks for help. I tried dkms method and still get the same output. I can use this module with secureboot disabled. I'm now asking on the fedora forum.

Update: This kernel module is successfully signed and loaded using the method in these two articles.

https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/kernel-module-driver-configuration/Working_with_Kernel_Modules/#sect-signing-kernel-modules-for-secure-boot

Now all issues related to this is solved. Thanks again for you guys' help.
