STRUCT VBLANK_CONTROL_WORK(9)

🦋 struct vblank_control_work(9) 🦋

okay so bestie, welcome to the Kernel API Manual ✨ — this is the whole vibe on struct vblank_control_work, and no cap, it's giving "small struct, big job." Let's get into it 💅

---

🌸 NAME 🌸

struct vblank_control_work — literally the work data for vblank control. that's it, that's the whole name, and she ate 🎀

---

⭐ SYNOPSIS ⭐

here's the struct in all her main-character glory, copied exactly so you don't have to squint at the source, iykyk:

struct vblank_control_work {
    struct work_struct work;
    struct amdgpu_display_manager *dm;
    struct amdgpu_crtc *acrtc;
    struct dc_stream_state *stream;
    bool enable;
 };

like, five fields, zero notes 💀

---

👑 Members 👑

these are the members, one by one, and yes we're doing all of them 🫶

• work — the kernel work data for the work event. this is the little engine that gets the whole thing scheduled ✨
• dm — the amdgpu display manager device. hi bestie, she's kind of a big deal 💖
• acrtc — the amdgpu CRTC instance for which the event has occurred. yes, that CRTC, the one the event happened on 🔥
• stream — the DC stream for which the event has occurred. the stream that said "not me being the one this event fired for" 😭
• enable — true if enabling vblank. like, that's the whole bool. true = we're turning it on, periodt 👑
