If the framebuffer tag was requested through the framebuffer tag header and its supported by the stivale bootloader, this tag is returned to the kernel. This tag provides an interface to the framebuffer.

Fields

header: StivaleTagHeader

framebuffer_addr: u64

The address of the framebuffer.

framebuffer_width: u16

The total width of the framebuffer in pixels.

framebuffer_height: u16

The total height of the framebuffer in pixels.

framebuffer_pitch: u16

The pitch of the framebuffer in bytes.

framebuffer_bpp: u16

The amount of bytes-per pixel.

memory_model: u8

Memory model of the framebuffer. If set to one, its RGB and all other values are undefined.

red_mask_size: u8

Size of the red mask in RGB.

red_mask_shift: u8

Shift of the red mask in RGB.

green_mask_size: u8

Size of the green mask in RGB.

green_mask_shift: u8

Shift of the green mask in RGB.

blue_mask_size: u8

Size of the blue mask in RGB.

blue_mask_shift: u8

Shift of the blue mask in RGB.

Implementations
