💅 drm_crtc_vblank_put(9)

okay so bestie, we're in the Kernel API Manual today and this one is a whole mood — it's the function that says "k, I'm done with the vblank events, someone else can have them" 🎀

✨ NAME ✨

drm_crtc_vblank_put — give up ownership of vblank events

like, literally hand the keys back. no cap. 🔑

🌸 SYNOPSIS 🌸

void drm_crtc_vblank_put (struct drm_crtc *crtc );

🦋 ARGUMENTS 🦋

  • crtc — which counter to give up 🫶 (yes bestie, which one — you gotta tell it)

💖 DESCRIPTION 💖

Okay so here's the tea ☕ — this one releases ownership of a given vblank counter, and it turns off interrupts if possible. Iconic behaviour, honestly.

And the timing? It disables interrupts after drm_vblank_crtc_config.offdelay_ms milliseconds. Not before, not whenever, after exactly that many milliseconds. the way that's so specific 💅
