Struct FramebufferResource 

pub struct FramebufferResource {
    pub source_device_id: usize,
    pub logical_name: String,
    pub config: FramebufferConfig,
    pub physical_addr: usize,
    pub size: usize,
    pub created_char_device_id: RwLock<Option<usize>>,
}

Framebuffer resource extracted from graphics devices

Fields

source_device_id: usize

DeviceManager’s device id

logical_name: String

Logical name for user access (e.g., “fb0”)

config: FramebufferConfig

Framebuffer configuration (resolution, format, etc.)

physical_addr: usize

Physical memory address of the framebuffer

size: usize

Size of the allocated framebuffer memory in bytes (page-aligned). This is the actual allocated size, which may be larger than the logical framebuffer size (config.size()) due to page alignment requirements. Use this size for memory mapping operations. For the logical pixel data size, use config.size() instead.

created_char_device_id: RwLock<Option<usize>>

ID of the created /dev/fbX character device (if any)

Implementations

impl FramebufferResource

pub fn new( source_device_id: usize, logical_name: String, config: FramebufferConfig, physical_addr: usize, size: usize, ) -> Self

Create a new framebuffer resource

Trait Implementations

impl Debug for FramebufferResource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
