Properties

DmaEntryLimit

public int DmaEntryLimit { get; set; }

Optional. Specifies the maximum number of DMA entries (pages) that can be mapped by the VFIO IOMMU type 1 driver for a container. This limit affects the total amount of host memory that can be pinned for direct device access, which is often critical for high-performance devices like TPUs and GPUs. This setting corresponds to the kernel parameter at: /sys/module/vfio_iommu_type1/parameters/dma_entry_limit. The default value in the kernel is 65535. Higher values may be needed for workloads mapping large memory regions. Supported values are integers between 65535 and 4194304.
