[Qemu-arm] [PATCH v2 0/6] ARM SMMUv3: Fix spurious notification errors and stall with vfio-pci |

This series fixes the guest stall observed when attempting to run
a guest exposed with a SMMUv3 and a VFIO-PCI device. As a reminder
SMMUv3 is not yet integrated with VFIO (the device will not work
properly) but this shouldn't prevent the guest from booting.
It also silences some spurious translation configuration decoding
errors (STE out of span or invalid STE) that may happen on guest IOVA
invalidation notifications.
Best Regards
Eric
History:
v1 -> v2:
- Added "memory: Remove unused memory_region_iommu_replay_all()" &
"hw/arm/smmuv3: Log a guest error when decoding an invalid STE"
- do not attempt to implement replay Cb but rather remove the call
in case it is not needed
- explain why we do not remove other log messages on config decoding
Eric Auger (6):
memory: Remove unused memory_region_iommu_replay_all()
memory: Add IOMMU_ATTR_VFIO_NESTED IOMMU memory region attribute
hw/vfio/common: Do not replay IOMMU mappings in nested case
hw/arm/smmuv3: Advertise VFIO_NESTED
hw/arm/smmuv3: Log a guest error when decoding an invalid STE
hw/arm/smmuv3: Remove spurious error messages on IOVA invalidations
