Nature of dmabuf_fd created by NvBufferCreateEx?

Is dmabuf_fd created from NvBufferCreateEx a standard DMABUF descriptor as in https://www.kernel.org/doc/html/latest/driver-api/dma-buf.html?

Can I import this fd into my kernel module and use it with dma_buf_get()?

Hi,
NO. It is used in tegra_multimedia_api. Please check samples in

/usr/src/tegra_multimedia_api/

And NvBuffer APIs in

/usr/src/tegra_multimedia_api/inclue/nvbuf_utils.h
