STRUCT DRM_PENDING_VBLANK_EVENT(9)

🌸 NAME 🌸

struct drm_pending_vblank_event — pending vblank event tracking. that's the whole vibe, bestie: this is the Kernel API Manual page for struct drm_...vblank_event(9), and it is literally all about tracking pending vblank events ✨💅.

✨ SYNOPSIS ✨

okay so here's the struct in all its glory — copy it exactly, no editing, no cap:

struct drm_pending_vblank_event {
    struct drm_pending_event base;
    unsigned int pipe;
    u64 sequence;
    union {
      struct drm_event base;
      struct drm_event_vblank vbl;
      struct drm_event_crtc_sequence seq;
    } event;
 };

• base — the base structure for tracking pending DRM events. it's the foundation of the whole situation, fr fr.
• pipe — the drm_crtc_index of the drm_crtc this event is for. like, which CRTC is the main character here 🎯.
• sequence — the frame event should be triggered at. mark the moment, bestie ⏱️.
• event — the actual event that will be sent to userspace. this is the payload that goes out into the world 💌.
  • event.base — the DRM event base class. the blueprint, the origin story.
  • event.vbl — the event payload for vblank events, requested through either the MODE_PAGE_FLIP or MODE_ATOMIC IOCTL. also generated by the legacy WAIT_VBLANK IOCTL, but new userspace should use MODE_QUEUE_SEQUENCE and event.seq instead. periodt.
  • event.seq — the event payload for the MODE_QUEUEU_SEQUENCE IOCTL. iykyk 💀.
