Hi,

Changes from v4:
 https://lore.kernel.org/qemu-devel/20260204190008.20070-1-skolothumtho@nvidia.com/
 
 -Addressed feedback and picked up tags. Thanks!
 -Fixed missing !accel check in smmuv3_accel_alloc_veventq(patch #3)

I think this is now ready for inclusion. Please take a look and let me know.

Thanks,
Shameer

Background(From v2):

When accel=on is enabled for an SMMUv3 instance, the host hardware SMMUv3
may generate Stage-1 (S1) event notifications that are intended for the
vIOMMU instance in userspace.

This series adds QEMU support for receiving such host events through the
vEVENTQ interface and propagating them to the guest. The implementation
uses the vEVENTQ support provided by the IOMMUFD subsystem in the kernel.

I have tested this on a Grace platform using some hacks to generate
events. Further testing and feedback are welcome.
