Re: [RFC PATCH 0/5] hw/arm/virt: Add support for user-creatable nested SMMUv3

Hi Shameer,

Could you share the branch/version of the boot firmware file 
"QEMU_EFI.fd" from your example, and where you retrieved it from? I've 
been encountering PCI host bridge resource conflicts whenever assigning 
more than one passthrough device to a multi-vSMMU VM, booting with the 
boot firmware provided by qemu-efi-aarch64 version 2024.02-2. This 
prevents the VM from booting, eventually dropping into the UEFI shell 
with an error message indicating DMA mapping failed for the passthrough 
devices.

Thanks,
Nathan
