Hi Team,

  1. Does NVCSI/VI5 driver support DMA buffer?
  2. Is it possible to implement a DMA buffer in NVCSI/VI driver to use DMA for data capturing?

Thanks,
Ajith.

Current NVCSI/VI driver did support DMA buffer capture.

Hi @ShaneCCC

Do I need to do some configurations to invoke the DMA buffer or it is already using the DMA buffer for capture?

Thanks,
Ajith.

It’s already using v4l2 DMA buffer already.
