In any event it's x86-only and hence would rather belong ... I decided so because the patch series [1] seems to be fully merged.

Yes, it should be moved to x86. Based on the which files were changed during this patch series I decided that it should be in hypervisor changes, but now I checked which changes specifically done and for Arm it was added basically only stubs in libxl_arm.c. ~ Oleksii

I've spoken with Jiqian from AMD and the QEMU side is still pending to be merged, so I'm not sure I would list it here yet. Also AFAICT the current work just enables passthrough from a PVH dom0 to an HVM domU, but not to PV domUs. This would need to be clarified. Thanks, Roger.

Yes, I only added pci passthrough for HVM domUs when dom0 is PVH. And the qemu patch isn't merged yet. https://lore.kernel.org/xen-devel/BL1PR12MB58491271C360CE4345A915AFE7C02@BL1PR12MB5849.namprd12.prod.outlook.com/ I think we need to wait qemu patch merged and then you can add an entry like: - On x86: - Support pci passthrough for HVM domUs when dom0 is PVH. > > Thanks, Roger. >

Thanks for clarifying. I will drop that for now. Best regards, Oleksii
