Subject: [PATCH v2 4/7] hw/arm/smmu-common: Fix smmu_iotlb_inv_iova when asid is not set
Date: Thu, 25 Feb 2021 10:14:32 +0100 [thread overview]
Message-ID: <20210225091435.644762-5-eric.auger@redhat.com> (raw)
In-Reply-To: <20210225091435.644762-1-eric.auger@redhat.com>
If the asid is not set, do not attempt to locate the key directly
as all inserted keys have a valid asid.
Use g_hash_table_foreach_remove instead.
