Darktable opencl rusticl

junakreiter · 2025-08-29 13:37:42

Hi There,
A year ago i could rusticl get working with darktable.
A few weeks ago rusticl had been integrated into opencl-mesa. (if i am not wrong)
A few days ago, again, opencl stopped workig with darktable.
Can somebody help me with what the problem is ?
cheers !

A few weeks ago rusticl had been integrated into opencl-mesa. (if i am not wrong)

long ago mesa had one opencl implementation , clover .
When rusticl was started the name openl-mesa was taken by clover, so rusticl got another pkgname .

Recently clover was completely removed from mesa code and the opencl-mesa pkgname was free and now used for rusticl.

Darktable was updated to 2:5.2.1-2 on 2025-08-28 , is that the version you are using ?

I am using the version you mentioned.
I have to downgrade opencl-mesa to get it working again.

The world goes crazy.

Gitlab login wants me to install an app on my phone for proving my identitiy.

So i am technically not able to file that bug, im sorry.

If you're in the UK use TOR browser to avoid the recent legislation in respect of "adult" websites. Reddit also requires verification in the UK now.

No need for an app on a smartphone, the text is misleading.

Once you get login details from accountsupport@archlinux.org by email , all you need is something that supports OATH TOTP.
Several passwordmanagers do support that, there's a pam module for it etc.

See https://wiki.archlinux.org/title/Initia … entication

Thanks Lone_Wolf

My Son found a workaround for a darktable problem:
Open darktable like this:

OPENCL_VENDOR_PATH=/etc/OpenCL/vendors/rusticl.icd darktable

That environment value is documented on https://man.archlinux.org/man/libOpenCL.7 .
Maybe it could be added to the gpgpu wiki page.

Please use code tags for log output to make things a lot more readable .(Edit your post to add the tags) .

glenjo · 2025-10-11 05:33:26

I had the same problem. I switched to using ROCm from RustiCL in darktable (in preferences->processing->OpenCL drivers). This allowed OpenCL GPU acceleration to be activated.

Hi!

I investigated the crash on my dads pc and this is how I solved it.

opencl-mesa darktable crash on AMD Radeon Pro W6400

local/ocl-icd 2.3.3-1
    OpenCL ICD Bindings
local/opencl-mesa 1:25.2.4-1
    Open-source OpenCL drivers
local/darktable 2:5.2.1-3
    Utility to organize and develop raw images

--> CRASH

fix ocl-icd crash

Updated PKGBUILD for ocl-icd to use the 2.3.4 tag which fixes some memory corruption in the _sort_platforms.

Try out mesa-git -> FIXED

TLDR:
- ocl-icd 2.3.4 was already released and fixes the startup problem. It has not arrived in the arch repos yet though.
- mesa-git fixes the second crash so it should fix itself in the next release cylce probably.

CHEERS, Max.
