AMD Open-Source GPU Kernel Driver Above 5M Lines, Entire Linux Kernel at 34.8M
AMD Open-Source GPU Kernel Driver Above 5M Lines, Entire Linux Kernel at 34.8M
There is a discussion on Hacker News, but feel free to comment here as well.
This is the best summary I could come up with:
With the in-development Linux 6.6 kernel adding support for more upcoming Radeon graphics processors, that means more auto-generated header files for the new IP blocks...
In particular, the drivers/gpu/drm/amd/ area that contains the modern code around the AMDGPU DRM driver with AMDKFD compute, display code, common header files, etc (but not counting the older "Radeon" driver in drivers/gpu/drm/radeon/).
This open-source AMD Linux kernel graphics driver amounts to more than 5 million lines: 2173 text files.
These verbose header files has been AMD's alternative to creating exhaustive public documentation on their GPUs that they were once known for.
Or the Intel i915 DRM kernel graphics driver is around 381k lines via the same cloc judgment.
The entire Linux kernel source tree as of this morning comes in at around 34.8 million lines, including the documentation, various in-tree utilities/tools, other helpers, etc.
