    • hasDmaEntryLimit

      public boolean hasDmaEntryLimit()
       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`.
      optional int32 dma_entry_limit = 1 [(.google.api.field_behavior) = OPTIONAL];
      Specified by:
      hasDmaEntryLimit in interface LinuxNodeConfig.NodeVfioConfigOrBuilder
      Returns:
      Whether the dmaEntryLimit field is set.

    • getDmaEntryLimit

      public int getDmaEntryLimit()
       Optional. Specifies the maximum number of DMA entries (pages) that can be

      getDmaEntryLimit in interface LinuxNodeConfig.NodeVfioConfigOrBuilder
      Returns:
      The dmaEntryLimit.
