How to properly configure OpenCL runtime with old AMD gpu?

I'm trying to get my old AMD HD7850 (Pitcairn / S. Islands) graphics card to work with hashcat, but I've having trouble properly configuring the OpenCL backend.

Since it's a 10+ year old device, none of the ROCm AMD runtime binaries work, so I'm left with the implementations provided by mesa; clover seems to work (detected with clinfo), but hashcat complains

* Device #1: Unstable OpenCL driver detected!

No devices found/left.

I can pass the --force to ignore the error and continue, but the computer will eventually crash.
Alternatively, with opencl-rusticl-mesa,  clinfo does not identify any compatible device, although it is should (allegedly):

even when calling export RUSTICL_ENABLE=amdgpu beforehand.

Anyone with a similar setup/experience that can provide some feedback here? Thanks in advance.

Re: How to properly configure OpenCL runtime with old AMD gpu?

rusticl expects to be given the mesa driver it should use, not the kernel module.
https://docs.mesa3d.org/envvars.html#ru … -variables for details.

I'm not sure if your card will work with rusticl, but we can verify that.

Please post output of

$ RUSTICL_ENABLE=radeonsi clinfo --list

clean chroot building not flexible enough ?

Indeed that was the issue. For some reason I misread that argument as radeon and though it was referring to the driver in use.
clinfo is now able to identify the GPU, and hashcat no longer complains.

Platform #0: rusticl
 `-- Device #0: AMD Radeon HD 7800 Series (pitcairn, LLVM 16.0.6, DRM 3.54, 6.6.1-arch1-1)

Great, please prepend [Solved] to the thread ttitle.
(edit first post, you may need to shorten the title ).
