saw ref. to this from Phoronix forums.. ===copy== XanMod is a general-purpose Linux kernel distribution with custom settings and new features. Built to provide a stable, responsive and smooth desktop experience. The real-time version is recommended for critical runtime applications such as Linux gaming eSports, streaming, live productions and ultra-low latency enthusiasts. Supports all recent x86_64 versions of Ubuntu / Debian-based systems. Note: The current proprietary NVIDIA, VirtualBox, VMware Workstation / Player and some other dkms modules builds do not officially support Clang'ed (EDGE) and RT kernels. ===copy end== site https://xanmod.org/ I wonder how it may interact with Cinelerra(s) - because there we use threads and some internal scheduling tricks....
