Subject: [PATCH v4 02/19] vfio/container: Introduce TYPE_HOST_IOMMU_DEVICE_LEGACY_VFIO device
Date: Tue,  7 May 2024 17:20:26 +0800	[thread overview]
Message-ID: <20240507092043.1172717-3-zhenzhong.duan@intel.com> (raw)
In-Reply-To: <20240507092043.1172717-1-zhenzhong.duan@intel.com>

TYPE_HOST_IOMMU_DEVICE_LEGACY_VFIO represents a host IOMMU device under
VFIO legacy container backend.

It will have its own realize implementation.
