Hi there,
I'd like to know when you add support for an ati radeon HD 7790, I've got a some of them but can't use it with "Linux zerg 4.4.0-87-generic #110~14.04.1-Ubuntu SMP Tue Jul 18 14:51:32 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux " Here is hashcat reply
"""

Can not find an OpenCL ICD loader library
You're probably missing the OpenCL runtime and driver installation
* AMD users on Linux require "AMDGPU-Pro Driver" (16.40 or later)
* Intel CPU users require "OpenCL Runtime for Intel Core and Intel Xeon Processors" (16.1.1 or later)
* Intel GPU on Linux users require "OpenCL 2.0 GPU Driver Package for Linux" (2.0 or later)
* NVidia users require "NVIDIA Driver" (367.x or later)
