How to enable RusticCL with darktable 4.6? (opencl fails to init)

Software darktable
21

Going back and forth with Rusticl → Rocm → Opencl-Amd drivers resulted in system freezes, crashes and eventually I just gave up with OpenCL on DT.

Rusticl - Works great, no freezes, but Filmic module (and some other ones on TIF files) produces black screen. That’s not acceptable so I had it uninstalled.

Rocm - Same as Opencl-AMD, upon starting, DT can freeze the entire system with hardware reset being the only way.

OpenCL-AMD - same as Rocm, though it appears to have less freezes. But now, DT doesn’t always detect OpenCL drivers upon start. Also, sometimes DT won’t actually open the image(s). The moment I try, it enters the loop - the never ending “Loading xyz.cr3 file” message. I cannot seem to kill the app or the process.

I have a new AMD 6650XT card that should be supported by all drivers.
DT is the only app that I use that can freeze and crash the system.

22

You also run dt under wayland, which is explicitly not supported.

And you were asked to provide a raw file and its sidecar which show the “black screen with filmic”.
Until that’s done, I don’t think devs can do very much to help (provided they are interested, no idea how the situation wrt. to wayland is: “not supported” doesn’t imply they’re not working to get dt running under wayland)

23

It’s hard to send something when it happens with every file I imported.

It happens with CR3 RAWs, Tiffs, JPGs.
Filmic RGB produces black screen when working with Rusticl.

Also noticed the same with Color Balance RGB - another black image.

Tested all other modules, all ok.
So both Filmic and Color balance RGB make the image screen go black.
This happens on X11 and Wayland both.

Well, rustcl has not been concidered as stable so far. You might start darktable with ‘-d opencl -d verbose’ and share the log.

25

Today is the day of testing I guess.

To be honest, I’ve got so tired of seeing my PC freeze upon starting DT or DT being so unresponsive that even Linux couldn’t kill it at the shutdown for 4 minutes, that I have switched to X11.

On X11 both Opencl-Amd and Rocm opencl drivers work in DT blazingly fast. No crashes, no freezes.

I tested some other apps I use, that were always stable, but now they fly on X11 (Krita, Siril). Subjectively, much more responsive.

I will probably continue to stay away from Wayland until it gets features, speed, stability and support done. It was adopted way too early to be used for production, imo.

My OpenCL driver of choice for now is Rocm.

26

Well, rustcl has not been concidered as stable so far. You might start darktable with ‘-d opencl -d verbose’ and share the log.

Nothing’s really there I think.

However, when I fiddle with Filmic and Color balance RGB modules that are causing image blackouts under Rusticl, there’s no output in the console. As noted previously, Rusticl has the same problem both in in X11 and Wayland.

27

Since the latest MESA 23.3.4 update, Rusticl works nicely with Filmic & color balance modules - no more black screen.

Fingers crossed it’s stable as before for me. I’m back on using OpenCL again with DT on Wayland.

28

There have been quite a number of color maths problems in dt fixed in the last couple of weeks, could certainly have been the real culprit :slight_smile:

29

Yeah, but I’m still using 4.6. So far this version has been very stable for me.

I am still struggeling, too, with RustiCL and darktable. am trying to get my AMDGPU running with the RustiCL drivers on my Ubuntu 22.04 system. Probably one of the experts here can give me a hint … :wink:
When I am calling clinfo on my system, I am getting the following output, which looks fine to me:
