Use the clinfo package to check support.

This is from my system with a Vega 8 iGPU:

And this is from Blender:

To get that working I had to set this variable:

Code: Select all

# /etc/environment.d/00opencl.conf
CYCLES_OPENCL_SPLIT_KERNEL_TEST=1
We don't need no stinkin' AMDGPU-PRO... :mrgreen:

You forgot to tell us which packages you installed for OpenCL support.

Sorry. I forgot that I uninstalled mesa-opencl before doing clinfo.
I have 18.3.6 and no update was available after enabling backports.
OpenCL is still unavailable in Blender.

Here's my clinfo now :

I guess I need a newer mesa-opencl-icd version but I tried v20.0.4 for Debian sid and it told me that

Code: Select all

installing libc6:amd64 would break locales, and deconfiguration is not permitted
If this requires risky system modifications, I can wait until buster-backports have a newer version. And if they never do I can probably wait for the next Debian release if it's under or around a year of waiting. There's no rush for me. I have a dual boot with manjaro. Maybe I'll try to migrate all my work and pipeline there in the mean time.

Did you set the environmental variable I mentioned at the end of my last post before starting Blender?

Adding sid to a stable system is unwise unless you really know what you're doing. And if the package needs a newer glibc version then it won't be backported.

Yes I added that env. variable. The 00opencl.conf file didn't exist btw so I created it.

Again, those mesa open ICD packages are built as part of Mesa, and Debian hasn't backported them yet. AFAIK, MX 19 has the only Buster-based backports, and they also required some other updates in order to build. The most notable one is the llvm-9.0 toolchain, which takes me hours and hours to build on even a fairly powerful gaming laptop. Mesa 19.3.3 takes only a few minutes in comparison.

Our backported Mesas don't require a newer gcc or libc6--that's the beauty of backporting things the right way.
