Hello, trying to install ARC310 driver on Ubuntu Server 22.04 with 6.5 kernel and I get this error.

I am using

apt install -y intel-i915-dkms

Any suggestions, please?

I have the same issue with 5.15 kernel, the one actually recommended by the install guide.

Any solutions to try, please?

[FCM]

The guide at https://dgpu-docs.intel.com/driver/client/overview.html is not working, I can't build the module locally for either kernel 5.15 or 6.5 hwe.

Can some Intel Linux chad look at this please and give some pointers?

Should I post in a different area of the forums?

Root cause:

linux-hwe-6.5-headers-6.5.0-18/include/drm/display/drm_dp_mst_helper.h:835:int drm_dp_calc_pbn_mode(int clock, int bpp, bool dsc);
linux-hwe-6.5-headers-6.5.0-41/include/drm/display/drm_dp_mst_helper.h:835:int drm_dp_calc_pbn_mode(int clock, int bpp);

drm_dp_calc_pbn_mode() prototype has changed in 6.5.0-41, leading to mismatch with i915-dkms.

Possible solution:

After installing Ubuntu 22.04 (say 22.04.4), don't apt upgrade, especially don't install & upgrade linux-image-generic-hwe-22.04.

To turn off Ubuntu Unattended-Upgrades:

sudo systemctl disable --now unattended-upgrades

sudo nano /etc/apt/apt.conf.d/20auto-upgrades, setting Unattended-Upgrade as "0".

But this happens when I revert to the mainline non hwe kernel 5.15.

See attached crash log for details.
