The latest intel-igc-{core,opencl} cannot coexist with legacy packages

[nyanmisaka]

The legacy ICD requires (intel-igc-opencl = 1.0.17537.20), therefore, it is not possible to install both new and legacy compute-runtime in the same environment.

Thus, if our software is to support both platforms, we will have to stay on version 24.35.30872.22. This will cause problems when new platforms are introduced in the future, so please release a new version to resolve this version conflict.

Thanks @nyanmisaka
We are working with IGC team to resolve the issue.

[nyanmisaka]

@JablonskiMateusz One more question, Rocket Lake (UHD7xx) has the same Gen12 Gfx as Tiger Lake but is excluded from the latest supported list. Is it a typo?

Yes, that's a typo
@kmachnik FYI

[kmachnik]

Typo corrected. Rocket Lake again present in the supported platforms table.
Thank you for catching that!

To get legacy packages from 24.35 working together with 24.45 release, follow the steps below:

• start with a clean install of 24.35
• install driver 24.45 on top of it
• to resolve any inconsistencies, use:

apt-get install --fix-broken

@kmachnik
Thanks for the update! I can confirm that 24.45.31740.9 and 24.35.30872.22(legacy) can coexist on Ubuntu 24.04.

But I want to let you know that a new issue has appeared, that the prebuilt libigc2 packages no longer support Ubuntu 22.04, while the IGC README says that both 22.04 and 24.04 are supported.

The following packages have unmet dependencies:
 intel-igc-core-2 : Depends: libc6 (>= 2.38) but 2.35-0ubuntu3.8 is to be installed
 intel-igc-opencl-2 : Depends: libc6 (>= 2.38) but 2.35-0ubuntu3.8 is to be installed

This is because the packages built on 24.04 require a higher glibc version, which makes them incompatible with backwards. Is there any chance to fix this as well? Many users are still on 22.04 LTS.

@GermanAizek The packages provided in this repo replace the ones provided by Debian/Ubuntu, they will not be compatible with each other. So please don't hijack this thread as they are different things.

@nyanmisaka,
yes, I deleted all APT intel-opencl* and depends Debian packages as well as from ppa:intel and manually installed them from Github Releases. And it helped.
