Methods

getDmaEntryLimit()

public abstract int getDmaEntryLimit()

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];

Returns
Type Description
int

The dmaEntryLimit.
