While working on the Linux SMMUv3 driver, I noticed a few cases where the QEMU SMMUv3 behavior relating to stream tables was inconsistent with our hardware.
Also, when debugging those differences, I found that the errors reported through the QEMU SMMUv3 event queue contained the address fields in an incorrect position. These patches correct the QEMU SMMUv3 behavior to match the specification (and the behavior that I observed in our hardware). Linux guests normally will not notice these issues, but other SMMUv3 driver implementations might.
