    amdgpu-pro DRM (DKMS modules) driver internal questions for debug purpose

    krjdev

      Hello,

       

      First about:

      I'm an electronic engineer who currently interested in software programming, especially openCL.

      The open-source driver unfortunately doesn't support openCL, so I need the proprietary. But I have

      a problem with the proprietary driver under my system what I like to fix this by myself. I have posted

      the issue in the AMD Support forum. But I haven't get any answer yet.

       

      To figure out the problem, I need a little help please. So I have a couple of questions:

       

      Is there a short overview from the source code of the DKMS modules?

      How works the  memory management?

      Can I get the address of a specific DRM framebuffer, plane or overlay in the

      Video-Memory and verify/manipulate (with modification in the DKMS modules for

      debug purpose) it?

       

      Thanks in advance!

      As a precaution, if this post will declined again:

      DRM: I mean the Direct Rendering Manager, not the Digital Rights Management stuff.
