Subject: [PATCH v3 16/19] vfio: enable IOMMU_TYPE1 for RISC-V
Date: Fri, 7 Aug 2026 20:17:10 +0200 [thread overview]
Message-ID: <20260807181713.228535-17-andrew.jones@oss.qualcomm.com> (raw)
In-Reply-To: <20260807181713.228535-1-andrew.jones@oss.qualcomm.com>
From: Tomasz Jeznach <tjeznach@rivosinc.com>
Enable VFIO support on RISC-V architecture, now that the RISC-V IOMMU
driver reports the IOMMU_CAP_CACHE_COHERENCY capability VFIO_TYPE1 and
iommufd both require before allowing a device to be bound.
