Currently, SYCL 6.0+ is missing in the repository:

[...]
-- Could NOT find SYCL (missing: SYCL_LIBRARY SYCL_INCLUDE_DIR) 
-- Found LevelZero: /usr/lib64/libze_loader.so  
-- oneAPI not found, disabling WITH_CYCLES_DEVICE_ONEAPI
-- SYCL 6.0+ or Level Zero not found, disabling WITH_CYCLES_DEVICE_ONEAPI
[...]

One of Intel contributor is working on bring such support at this time of writing.

Is SYCL really a runtime dependency for Blender with oneAPI support? Because I can run Blender's own builds from their website (compiled with oneAPI support) just fine with only intel-compute-runtime and oneapi-level-zero installed from Fedora's repos.

It seems like SYCL is only required for compilation. But I guess Fedora's packaging guidelines require all build dependencies to also be available in the repository?

According to version.cmake (https://projects.blender.org/blender/blender/src/branch/main/build_files/build_environment/cmake/versions.cmake) file from Blender source, minimal version 20220919 of dpcpp (Intel SYCL currently as nightly release) is needed for compilation.

Logically, upstream Blender build uses compiler which is currently unavailable in Fedora repository.

Has any progress been made bringing sycl/dpcpp to Fedora yet or is there any way such progress can be followed somewhere?

I hope this doesn't come across as overly naggy, but is there any update on the state of this? Apparently there was already some work in progress to bring sycl to Fedora, but I suppose those plans haven't really materialized?

Not yet so far.

It would be a first step to see if one can make a dedicated build using this content:
https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html?operatingsystem=linux&distributions=dnf

For some reason, I was not able to install the toolkit on fedora-38...

Also maybe it worth to coordinate with frantisekz as he already has some components packaged as part of the intel-media-driver-free effort.
(https://copr.fedorainfracloud.org/coprs/frantisekz/intel-media-driver-free/packages/)

Lets add aekoroglu.com  who is also interested to maintain the oneAPI stack and @frantisekzfrantisekz to possibly package oneAPI-dpcpp.

Hello, I've started to work on oneAPI-dpcpp so this issue and the rest of the oneAPI-rendering-toolkit is in my OKRs to complete in Q3.

Thanks Ali. Changing the title to reflect the progress.

Any update for packaging oneAPI-dpcpp?

I've briefly looked into it, and as of now, if I am not missing anything, it's impossible to package this to Fedora. I wasn't able to find any sources for the dpcpp and its dependencies from the suite. eg. Archlinux packages just unpack the .deb files. It also comes with a bundled llvm (17, it seems) that may have some non-upstream patches.

The first step would be to have a source of this, then it may be possible to package it into Fedora (depending on the license, the arch package currently states "custom" which is a problem). Ali, do you have any idea/inside ways what to do with it?

Hello everyone,
We already started to discuss about this DPC++ issue with Red Hat and,
I will be preparing the compiler package for Fedora from https://github.com/intel/llvm "SYCL branch", which is a derivative of DPC++.

The compiler requires a minimum TBB version of 2021 but Fedora has shipped with version 2020.3
On the other hand, Fedora 40 will include TBB 2021.8 (https://fedoraproject.org/wiki/Changes/F40ModernizeTBB)
So, we should wait until TBB 2021.8 is successfully implemented in F40.

Thanks everyone for the updates and your work on this. That is great news with F40 around the corner. Seems like things slowly start to fall into place with all of Intel's oneapi stuff on Fedora. Hope this will be ready and in a usable state for F41 maybe.

Hello,
with Fedora 40 now officially released and TBB 2021.11 available in the repos, is there any progress update on your efforts to bring the necessary compiler package to Fedora?
