Subject: [PATCH v5 16/17] riscv: defconfig: Enable IOMMUFD and VFIO
Date: Mon, 31 Aug 2026 16:59:42 +0200 [thread overview]
Message-ID: <20260831145943.313726-17-andrew.jones@oss.qualcomm.com> (raw)
In-Reply-To: <20260831145943.313726-1-andrew.jones@oss.qualcomm.com>
Enable iommufd and VFIO in the default configuration now that the
RISC-V IOMMU provides the DMA and MSI remapping needed for userspace
device access, including assignment to virtual machines.
