    The Open-Source AMD GPU Linux Kernel Graphics Driver Nears 5.8 Million Lines

    Phoronix: The Open-Source AMD GPU Linux Kernel Graphics Driver Nears 5.8 Million Lines

    Last August I wrote an article about the open-source AMD GPU kernel driver crossing 5 million lines of code -- including their overzealous header files -- and following the recent Linux 6.11 merge window curiosity got the best of me with how much larger the kernel driver is now that the initial RDNA4 support is merged... Well, it's about to cross 5.8 million lines, or about a 16% increase just over the past year...

      It's not really, though. It's extensive register documentation. They're open-sourcing the ABI for their chips.

        Would you rather it all be "closed source" instead? Thought so.

        It might be a mess now but you can always contribute effort to a future code clean-up campaign. Linux development is always looking for more contributors.

          they should document it elsewhere. useless defines that are in most cases not used by any code and defined over and over for each revision of the hardware.

            They need one more blank assembly line.

              What a bunch of slackers, only 800k lines in a year!

              What have these people been doing all this time?

                Ok this may seem silly but by what standardisation in a "line" measured too?

                To me it's like saying how longs a piece of string !

                  It's the easiest metric we have, and more informative than the number of files. You could measure cyclomatic complexity, but that's harder.
