Cannot install amdgpu drivers on Ubuntu 20.04.1 (5.4.0-56-generic)

To install 5.4.0-54 do next:

sudo apt install linux-image-5.4.0-54-generic linux-headers-5.4.0-54-generic linux-modules-extra-5.4.0-54-generic

then reboot to 5.4.0-54

then

sudo apt remove linux-image-5.4.0-56-generic linux-image-unsigned-5.4.0-56-generic

(unsigned mentioned here because it tryed to install it for me by some reason.. it just helped)

then do

sudo apt autoremove

then go to /usr/src and remove linux-headers-5.4.0-56-generic and linux-headers-5.4.0-56 (if any of them are there)

now you can do

sudo ./amdgpu-install -y

OpenCL-OpenGL interoperation

Refer to Nvidia SDK named oclSimpleGL

Remeber to used correct OpenCL context.

IIRC, use

cl_context_properties props[] = 
    {
        CL_GL_CONTEXT_KHR, (cl_context_properties)glXGetCurrentContext(), 
        CL_GLX_DISPLAY_KHR, (cl_context_properties)glXGetCurrentDisplay(), 
        CL_CONTEXT_PLATFORM, (cl_context_properties)cpPlatform, 
        0
    };
