All of them are single GPU ones, but historically we have systems with: AMD RS780 NVIDIA (ION1, ION2 and some third one, for our workload, Nouveau is enough) AMD Kabini AMD Kaveri Intel D525 Most recently Intel J1900 The same OS must run on all of them, so it does make sense to build different drivers into Mesa but it was also a necessity to save space where we can. Hence the symlink solution. Custom made OS based on Yocto. Even if the hardlinks are used, bitbake in Yocto has a separate packaging stage after "make install" that copies files instead of moving them so even a single subpackage containing all drivers would end up with broken hardlinks, thus requiring multiples of what is needed solely for the gallium_dri.so and mesa_dri_drivers.so megadrivers. Maybe the megadrivers idea is the elephant in the room. I know it was created for a miniscule performance gain.
