Detailed Description

Buffer information for the IPA interface.

The IPABuffer structure associates buffer memory with a unique ID. It is used to map buffers to the IPA with IPAInterface::mapBuffers(), after which buffers will be identified by their ID in the IPA interface.

Member Data Documentation

id

libcamera::IPABuffer::id

The buffer unique ID.

Buffers mapped to the IPA are identified by numerical unique IDs. The IDs are chosen by the pipeline handler to fulfil the following constraints:

• IDs shall be positive integers different than zero
• IDs shall be unique among all mapped buffers

When buffers are unmapped with IPAInterface::unmapBuffers() their IDs are freed and may be reused for new buffer mappings.

planes

libcamera::IPABuffer::planes

The buffer planes description.

Stores the dmabuf handle and length for each plane of the buffer.
