[PATCH 0/5] hw/arm/smmuv3: Correct stream ID and event address handling

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

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.

Simon Veith (5):
  hw/arm/smmuv3: Apply address mask to linear strtab base address
  hw/arm/smmuv3: Check stream IDs against actual table LOG2SIZE
  hw/arm/smmuv3: Align stream table base address to table size
  hw/arm/smmuv3: Use correct bit positions in EVT_SET_ADDR2 macro
  hw/arm/smmuv3: Report F_STE_FETCH fault address in correct word
