      Fun fact: of the 1.2GB of Linux kernel source, a whole 200MB and all of the largest files are register bit definitions for AMD Radeon cards. This is because they are auto-generated, and contain bit definitions for every *instance* of every hardware unit, across many generations.pic.twitter.com/M3Vvp6m3iU

      What is the source material used to generate the 200MB ?

      Ask AMD :) But really I *hope* they have some kind of high-level description written in a macro language of some sort at least. If they really are maintaining a database of registers with 8 copies of each thing...

          I find it interesting how this whole GPU stack goes unnoticed by most kernel developers, yet they scream their lungs out about any potential neural net inferencing. They'd love to have all the input data, yet they don't care about 200 MB of unmaintainable nonsense right in there.

          This whole old gatekeeper-based development model has been at its limits for a while... The question is, what will it take for things to change. If they at least were consistent, but that they aren't and it depends on with whom you get drunk enough for them to like ya...
