For context, I’ve been leading the work on this cluster client-side (not the engineer that discovered the IOMMU fix) with Clyso.

There was no significant difference when testing between the latest HWE on Ubuntu 20.04 and kernel 6.2 on Ubuntu 22.04. In both cases we ran into the same IOMMU behaviour. Our tooling is all very much catered around Ubuntu so testing newer kernels with other distros just wasn’t feasible in the timescale we had to get this built. The plan was < 2 months from initial design to completion.

Awesome to see this on HN, we’re a pretty under-the-radar operation so there’s not much more I can say but proud to have worked on this!

Hey, thanks for the response! There have been a lot of across the board improvements in the kernel in the last four years so I'm surprised there's not a noticeable performance improvements in 6.2 (although I also consider 6.2 old at this point).
