+Subject: [PATCH] hw/arm/smmuv3: Support 16K translation granule
+
+The driver can query some bits in SMMUv3 IDR5 to learn which
+translation granules are supported. Arm recommends that SMMUv3
+implementations support at least 4K and 64K granules. But in
+the vSMMUv3, there seems to be no reason not to support 16K
+translation granule. In addition, if 16K is not supported,
+vSVA will failed to be enabled in the future for 16K guest
+kernel. So it'd better to support it.
