Instance Attribute Details

#dma_entry_limit ⇒ Fixnum

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. Corresponds to the JSON property dmaEntryLimit

Returns:

  • (Fixnum)
