Subject: [PATCH v3 6/6] iommu/virtio: Enable x86 support
Date: Fri, 21 Aug 2020 15:15:40 +0200	[thread overview]
Message-ID: <20200821131540.2801801-7-jean-philippe@linaro.org> (raw)
In-Reply-To: <20200821131540.2801801-1-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.
