Has anyone successfully turned on iommu on rk3588?

I apologize in advance, my device is nanopc-t6 rk3588, using pve installed on armbian, I can't use pci passthrough, I would like to ask if anyone has succeeded in pci passthrough!

I would greet any improvement in the IOMMU situation, as my main aim with this board is to develop a proxmox server. ATM with broken IOMMU it is quite a PITA.

Fantastic Stephen! It's the first evidence something is moving, since months! Thank you for this excellent tip!

Did you ever figure this out. Been messing around for a while and not getting anywhere. Any help would be much appreciated.

Hello Scott, no unfortunately I didn't even start implementing what Stephen suggested.
But in the meantime something is moving, I think.

At this link I see on 2nd December someone is applying a patch to show the pci segment of rk3588. Dunno what it means for us in practice. Surely @Joshua-Riek knows better where to start in order to adopt this future kernel improvement.
