STRUCT DRM_VBLANK_CRTC_CONFIG(9)

💅 NAME 💅

struct drm_vblank_crtc_config — the vblank configuration situation for a CRTC, bestie ✨

Oh and real quick, this whole thing lives in the Kernel API Manual and the page is literally called struct drm_..._crtc_config(9), iykyk 🫶

---

🌸 SYNOPSIS 🌸

struct drm_vblank_crtc_config {
    int offdelay_ms;
    bool disable_immediate;
 };

---

🎀 Members 🎀

• offdelay_ms — the vblank off delay, in ms 🕐 This is the icon that decides how long drm_vblank_crtc.disable_timer waits before it disables. Like it's literally standing there counting down 💀

It defaults to the value of drm_vblank_offdelay in drm_crtc_vblank_on.

• disable_immediate — go read drm_device.vblank_disable_immediate for the exact semantics of immediate vblank disabling, no cap 👑

Also — and this is the important part — this tracks the disable immediate value per crtc, just in case it needs to differ from the default value for a given device. So every CRTC gets its own little main character moment 🌈

It defaults to the value of drm_device.vblank_disable_immediate in drm_crtc_vblank_on.
