is the adress mapped virtual Address or phisical Address?

Hi Nvidia:
Function NvBuffer::NvBuffer( enum v4l2_buf_type buf_type, enum v4l2_memory memory_type, uint32_t n_planes,
NvBufferPlaneFormat * fmt, uint32_t index )
constructor a NvBuffer, assume the NvBuffer parameter is nvBuf,
question: nvBuf.planes[0].data is the mapped virtual Address or phisical Address of NvBuffer plane[0]?

Thanks! Expected your reply soon!

hello feng.baoying,

please refer to the [L4T MMAPI] from the documentation,
int NvBufferCreate () is allocate HW buffers, and int NvBufferMemMap () for getting mem mapped virtual address of the plane.
