Add support for Radeon Instinct MI25 MxGPU

[ashbuilds]

I have tried running nanominer in Ubuntu 18.04 with AMD Vega 10 Radeon Instinct MI25 MxGPU but it shows 0 devices.

I wonder if there is a possibility to run nanominer with this device?

[Grumpy-Dwarf]

It is supported. Do you have amdgpu-pro installed? What does clinfo command says about available AMD platform OpenCL devices?

Hi, Yes below I have attached the screenshot of info:

What does clinfo | grep "Device Name" say?

ASIC name is gfx900 just like Vega 56/64 has. Should work theoretically but miner even doesn't see the device, this is odd. What files do you have in /etc/OpenCL/vendors/ folder? It contains files with paths to OpenCL library implementations.

Looks like the problem is not with Radeon Instinct MI25 itself but with OpenCL setup.

Hi @Grumpy-Dwarf, There are two files:
