From dcda883cd21125c699419a3fc0fe182ea989d9c4 Mon Sep 17 00:00:00 2001 From: Zenghui Yu Date: Sat, 30 Jan 2021 12:32:20 +0800 Subject: hw/arm/smmuv3: Fix addr_mask for range-based invalidation When handling guest range-based IOTLB invalidation, we should decode the TG field into the corresponding translation granule size so that we can pass the correct invalidation range to backend. Set @granule to (tg * 2 + 10) to properly emulate the architecture.
