Nitrux uses the Liquorix kernel, described as “an enthusiast Linux kernel designed for uncompromised responsiveness in interactive systems, enabling low latency in A/V production, and reduced frame time deviations in games.”
It also uses OpenRC instead of systemd. New in this release is kboot, a utility to switch kernels on-the-fly without needing a reboot, and VMetal, which allows users to run Windows in parallel to Nitrux to provide users of access to Windows software.
Not sure what firmware limiters you’re talking about? I’m using a cheap ASUS board (B450i-gaming), a Zen 2 CPU and a 6600 XT, and single GPU passthru works just fine for me on Arch using this guide. (I haven’t tried VMetal or this new release of Nitrux yet). Yes, some manufactures are iffy about IOMMU support, mostly Intel-CPU and Intel-based boards in my experience, but if you’re using AMD you should be fine.
There is something called an ACS override patch, but that’s a kernel patch not a GPU firmware patch, and from my understanding, that’s for dual-GPU users. Regardless, it doesn’t modify your firmware in any way.
The same limitation mentioned it the guide you shared:
Also thanks for sharing it. I will try it some other time. 🙂
Only 10xx is affected or older cards are too ?? 😑
