No, it should always be in mainline.
I didn't see anything obviously wrong in your setup. A simplest QEMU cmdline
to boot a guest with vIOMMU should be:
$QEMU -machine q35,kernel-irqchip=split,accel=kvm -smp 4 -m 2G \
-device intel-iommu ~/images/default.qcow2
May worth try this directly. Also feel free to compile the latest QEMU. The
default configuration should work.
