Detailed Description

Structure holding DMA planes data for an SRMBuffer.

Use this structure to create SRM buffers from DMA planes data using the srmBufferCreateFromDMA() function.

Note

It's important to clarify that DMA planes are distinct from DRM planes (SRMPlane). Be cautious not to conflate these concepts.

Field Documentation
