Re: Blender doesn't detect Intel Arc GPU using intel-oneapi-common

Same boat: Blender doesn't detect my Intel Arc B580 external GPU: "No compatible GPUs found for Cycles." I got intel-compute-runtime and level-zero-loader installed, as well as CYCLES_ONEAPI_ALL_DEVICES=1, as per the instructions here. Blender version is the latest provided by Arch (4.5.2).

Am I missing anything?

Re: Blender doesn't detect Intel Arc GPU using intel-oneapi-common

Does it work w/ https://archlinux.org/packages/extra/x8 … i-basekit/ ?
OP was trying to figure which libraries are the critical difference, no idea whether he made any progress on that - see the previous posts.

No it does not. Just to recap, I got intel-compute-runtime, level-zero-loader, and intel-oneapi-basekit installed, and CYCLES_ONEAPI_ALL_DEVICES set to 1.

@CVI2, have you made any progress in this regard? Did you manage to make Blender see your Arc graphics card?

Re: Blender doesn't detect Intel Arc GPU using intel-oneapi-common

I'm having the same issue: Blender can't detect my Ultra 5 225h integrated graphics. I've installed Intel Compute Runtime and level-zero-loader, and also tried the other methods mentioned above, but still no luck. I'm wondering if there are any latest updates on this problem?

Re: Blender doesn't detect Intel Arc GPU using intel-oneapi-common

'key - brute force: what if you just keep all the listed libraries from baskit?
Also

grep wait_tree_vertex_interface /opt/intel/oneapi/compiler/2025.0/lib/libimf.so /opt/intel/oneapi/compiler/2025.0/lib/libintlc.so.5 /opt/intel/oneapi/compiler/2025.0/lib/libiomp5.so /opt/intel/oneapi/compiler/2025.0/lib/libirng.so /opt/intel/oneapi/compiler/2025.0/lib/libOpenCL.so.1 /opt/intel/oneapi/compiler/2025.0/lib/libsvml.so /opt/intel/oneapi/compiler/2025.0/lib/libsycl.so.8 /opt/intel/oneapi/compiler/2025.0/lib/libur_adapter_level_zero.so.0 /opt/intel/oneapi/compiler/2025.0/lib/libur_loader.so.0 /opt/intel/oneapi/compiler/2025.0/lib/sycl.conf /opt/intel/oneapi/debugger/2025.0/opt/debugger/lib/libyaml-cpp.so.0.8 /opt/intel/oneapi/tcm/1.2/lib/libhwloc.so.15 /opt/intel/oneapi/tcm/1.2/lib/libtcm.so.1 /opt/intel/oneapi/umf/0.9/lib/libumf.so.0

How exactly do you mean?
And sorry it took this long. I had some exams I had to take care of and I honestly forgot this thread exists.

This list:
https://bbs.archlinux.org/viewtopic.php … 3#p2253133

The idea was to keep all the baskit libraries (also not replace them), see whether that works and then what you can get away w/ removing/replacing to ultimately let the packager know where the problem is.

Re: Blender doesn't detect Intel Arc GPU using intel-oneapi-common

This is how I fixed the issue:
So step by step:

1. install intel-oneapi-basekit
2. copy  /opt/intel/oneapi/umf directory from basekit elsewhere
3. removed intel-oneapi-basekit
4. reinstalled blender along its dependencies
5. copied the umf directory I copied earlier to /opt/intel/oneapi
6. deleted the /opt/intel/oneapi/tbb directory and uninstalled intel-oneapi-tbb
7. sourced /opt/intel/oneapi/setvars.sh from shell and then opened blender in the same shell
8. profit

Re: Blender doesn't detect Intel Arc GPU using intel-oneapi-common

I'm in the same boat, the default blender package doesn't detect mu Arc A750.

Can confirm some CVI2 findings, specifically that installing the full intel-oneapi-basekit and running blender (previously sourcing `setvars.sh`) correctly detects the GPU. Setting `CYCLES_ONEAPI_ALL_DEVICES=1` isn't necessary.

Didn't try to isolate the libumf solution, but i can try to if it's useful.

Re: Blender doesn't detect Intel Arc GPU using intel-oneapi-common

iow there needs to be some intel-oneapi-umf split package?!
opt/intel/oneapi/umf/ looks ridiculously small comapared to the basekit - has anyone filed a bug against the package?

Re: Blender doesn't detect Intel Arc GPU using intel-oneapi-common

I've just ran into this issue and haven't found a fix (currently just on blenders binary builds). I've looked in the arch package issues, haven't seen a bug filed there. I don't think that I understand the issue good enough to file the report, but wanted to call that out.
