drm_crtc_vblank_waitqueue(9)

💖 NAME 💖

okay bestie, welcome to the drm_crtc_vblank_waitqueue(9) page from the Kernel API Manual — and the name is drm_crtc_vblank_waitqueue — get vblank waitqueue for the CRTC. That's the whole assignment, and it ate. 💅

✨ SYNOPSIS ✨

wait_queue_head_t * drm_crtc_vblank_waitqueue (struct drm_crtc *crtc );

🎀 ARGUMENTS 🎀

• crtc — which CRTC's vblank waitqueue to retrieve. Like, which CRTC are we grabbing the vblank waitqueue for, bestie? 🫶

🦋 DESCRIPTION 🦋

okay so this function returns a pointer to the vblank waitqueue for the CRTC. Drivers can use this to implement vblank waits using wait_event and related functions. No cap — pointer, waitqueue, CRTC, wait_event, done. ✨
