So why mixing a ᴄᴘᴜ and a fast ɢᴘᴜ isn’t a problem in OpenCl ?

llvmpipe is essentially an opersource driver itself (the difference is only not
requiring in‑kernel part). So generally when a modern Linux distro ship
llvmpipe, it also makes sure Opensource drivers (with their kernel modules) for
Nvidia ; Intel ; ᴀᴍᴅ are also installed and loaded.

Hence the LIBGL_ALWAYS_SOFTWARE=1 so widely used on phoronix.com for
benchmarking llvmpipe.
