xen passthrough devices for imx8quadmax mek

My target is imx8 quadmax mek. I would like to run xen on it and on top of that 2 or 3 (android/linux) guests need to be run.

Regarding device assignments to each of the domain I do have some points to clear. Please help me to get it clarified. I know target resources can be passthrough to the guest if the resource is only used by that guest. I would like to know which all resources are possible to passthrough to the guests and which all are limited to use only via the dom0. Do you have any documents to share regarding resource sharing /assignment of imx8quadmax mek?

Thank you for your reply.

I have already gone through the mentioned link. It just gives an example.

I would like to have a quite overview regarding all the resources capability to passthrough.

what do you mean "a quite overview"? You could passthrough any resources that have iomem capability. But only if you need DMA capability, SMMU is a must for the device.

You could check Android auto on xen release published recently. Check the dom0 dts for 8QM.
