Is hashcat working in linux with amd gpu?

[darkside]

I want to buy 6900xt GPU
I use arch linux.

I tried to find useful information, but I'm out of luck.

It seems that there are problems with OpenCL support for rdna2
I've found something abut rocm, but no really useful info.

There is post on the forum with supported hardware.
I checked ROCm docs and there is only one supported GPU from RDNA and it is AMD Radeon™ Pro W6800

On the forum, there are benchmark results from Windows. Is it working on Windows and not on Linux?

Currently, pretty much every GPU related topic is about gaming.

Amd works with Opencl and HIP , use of arch may cause issues with rocm, only certain linux kernels are compatible with rocm out of the box. I am using ubuntu 20.04 with 5.13.0 . And yes information about supported models / operating systems from AMD is severely lacking

Had the same problem with my rx590 on Arch. Remove hashcat and install hashcat-git from aur.
Also remove the current opencl driver and install opencl-amd from aur.

If you want gpu just for hash cracking, you should go with nvidia.

I think that to use OpenCL on your 6900xt GPU, you need to install the appropriate drivers and libraries for your system.
You can install the latest Pro Radeon drivers (version 21.10) using the command:

./amdgpu-pro-install -y --opencl=pal,legacy

This will install the AMDGPU-PRO driver and the OpenCL runtime for both legacy and PAL (Platform Abstraction Layer) devices. The 6900xt GPU belongs to the RDNA 2 architecture, which is supported by the PAL runtime.
