ExtMemPointer

Defined in cupva_types.h

struct ExtMemPointer

Structure to hold information about buffers not stored in VMEM.

Typedef provided for compatibility.

This object may be populated prior to VPU kernel launch from a device pointer by the host API using Parameter APIs (see cupva::Parameter::operator=). It may also be filled explicitly with cupvaGetL2ExtMemPointer().

• Maturity: GA

  Deprecated:

  VPUSymbolPointerData is deprecated, use ExtMemPointer instead

The type VPUSymbolPointerData has been renamed to ExtMemPointer to better reflect its purpose. This typedef is provided for compatibility reasons, and will be removed in a future release.

uint64_t base

Base IOVA. PVA only uses the lower 40-bit of base for storing IOVA and the most significant byte is reserved for storing memory type.

uint64_t offset

Offset in bytes. User-side pointer corresponds to location specified by base+offset sum

uint64_t size

Total mapped region size in bytes. Any location between [base, base+size) is legal to access
