void ConvertToGeometry(cupva::mem::SurfaceAttributes const &attr, int32_t const bpp, PlanarGeometry &geom)

Convert the surface attributes to planar geometry.

void Free(void *const devicePtr)

Free the allocated memory.

void * GetHostPointer(void *const devicePtr)

Get the host CPU mapped pointer for the given PVA pointer.

void * GetL2BaseAddress()

Request a device pointer to the L2SRAM (Orin Only).

void GetPointerAttributes(const void *const devicePtr, PointerAttributes &attr)

Query the pointer attributes for the given PVA pointer.

void GetSurfaceAttributes(const void *const devicePtr, SurfaceAttributes &attr)
