>If you're not intimately familiar with GPU drivers and what goes on this gives you a very quick, back-of-the-envelope of the size and complexity of the work involved. 1/7th the size and complexity of the kernel for this one driver.
ehh, no.
almost all of this are header files
>Meanwhile the open-source NVIDIA "Nouveau" driver is around 201k (21.7k blank lines, 24.3k lines of comments, and 155k lines of code). Or the Intel i915 DRM kernel graphics driver is around 381k lines via the same cloc judgment.
so it seems like GPU driver is around 1% of kernel's code
and you start thinking why actually kernel has this much code if GPU (out of all software) needs just around 1%.
