Subject: [PATCH 3/3] iommu/virtio: Enable x86 support
Date: Tue, 16 Mar 2021 20:16:54 +0100
Message-ID: <20210316191652.3401335-4-jean-philippe@linaro.org> (raw)
In-Reply-To: <20210316191652.3401335-1-jean-philippe@linaro.org>

With the VIOT support in place, x86 platforms can now use the
virtio-iommu.

The arm64 Kconfig selects IOMMU_DMA, while x86 IOMMU drivers select it
themselves.
