Struct SramConfig 

pub struct SramConfig {
    pub ctrl_base: usize,
    pub ctrl_offset: usize,
    pub owner_mask: u32,
    pub de2_owner: u32,
}

Configuration of the Allwinner SRAM controller (SRAMC) region that the Display Engine 2 must own to operate.

The exact register layout differs across sunxi SoC generations; platform code (board support / DeviceTree) supplies it explicitly : mirroring the sunxi_sram_claim() DT-driven flow in Linux (drivers/soc/sunxi/sunxi_sram.c).

Fields

ctrl_base: usize

Physical base address of the SRAM controller register block (A64: 0x01C0_0000).

ctrl_offset: usize

Offset of the control register owning the DE2 SRAM region.

owner_mask: u32

Mask of the ownership field inside the control register.

de2_owner: u32

Value within the field selecting the display engine as owner.

Implementations

impl SramConfig

fn apply_field(current: u32, cfg: &Self) -> u32

Applies de2_owner into the masked field of current.
