Expand description

EL0 プロセスとカーネル側 UserApp が共有するウィンドウ状態

Fields§

§width: u32§height: u32§pixels: Vec<u32>

提出済みピクセル (ARGB8888, width*height)。EL0 から SYS_WIN_BLIT でコピーされる

§events: VecDeque<u64>

UserApp が積み、EL0 が SYS_WIN_POLL で取り出す入力イベント

§open: bool

ウィンドウがまだ開いているか（false = ユーザが閉じた / プロセスが閉じた）

§fresh: bool

新しいピクセルが提出されたか
