Struct DmaBufPlane 

pub struct DmaBufPlane {
    pub resource_id: u32,
    pub offset: u32,
    pub stride: u32,
    pub modifier_hi: u32,
    pub modifier_lo: u32,
}

Single plane of a DMA-BUF.

Multi-planar formats (e.g., NV12) have one plane per component. Most RGB formats use a single plane.

Fields

resource_id: u32

Virtio-GPU resource ID (VeridianOS DMA-BUF handle).

On Linux this would be a file descriptor; on VeridianOS we use the virtio-gpu resource ID directly.

offset: u32

Byte offset into the resource where this plane starts

stride: u32

Byte stride (distance between rows) for this plane

modifier_hi: u32

Upper 32 bits of the 64-bit format modifier

modifier_lo: u32

Lower 32 bits of the 64-bit format modifier

Implementations

impl DmaBufPlane

pub fn modifier(&self) -> u64
