int
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.
This field is a member of oneof_ _dma_entry_limit.
