--- Comment #19 from [email protected] --- (In reply to Marek Olšák from comment #18) > A fast GPU + slow GPU is also a bad idea. There is the risk of improper load > balancing resulting in the performance being the same or slightly above the > slow GPU. Or if it's done badly, it can be well below the slow GPU. So why mixing a ᴄᴘᴜ and a fast ɢᴘᴜ isn’t a problem in OpenCl ? > You are also completely missing the main use case for llvmpipe: to have > desktop compositing if an OpenGL driver isn't installed or doesn't exist. > Nobody cares about supercomputers. 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. -- You are receiving this mail because: You are the QA Contact for the bug.
