Subject: [PATCH v2 3/3] iommu/virtio: Enable x86 support
Date: Fri, 28 Feb 2020 18:25:38 +0100	[thread overview]
Message-ID: <20200228172537.377327-4-jean-philippe@linaro.org> (raw)
In-Reply-To: <20200228172537.377327-1-jean-philippe@linaro.org>

With the built-in topology description in place, x86 platforms can now
use the virtio-iommu.

Architectures that use the generic iommu_dma_ops should normally select
CONFIG_IOMMU_DMA themselves (from arch/*/Kconfig). Since not all x86
drivers have been converted yet, it's currently up to the IOMMU Kconfig
to select it.
