DRM_CRTC_HEL...VBLANK_FUNCS(9)

💅 DRM_CRTC_HEL...VBLANK_FUNCS(9) — like, the Kernel API Manual page you didn't know you needed

okay so bestie, welcome to the Kernel API Manual ✨ this one's a short little baddie but she's important, and yes the title is truncated with ... in the middle — that's not a typo, that's just how man do 🎀

🌸 NAME 🌸

DRM_CRTC_HELPER_VBLANK_FUNCS — the default implementation for VBLANK helpers, no cap 💅

⭐ SYNOPSIS ⭐

DRM_CRTC_HELPER_VBLANK_FUNCS

that's it. that's the whole synopsis. she's a macro, she doesn't need a whole paragraph 🦋

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this macro initializes struct drm_crtc_helper_funcs to the default helpers for VBLANK handling ✨

literally that's her whole job. she sets up your struct drm_crtc_helper_funcs with the default VBLANK handling helpers so you don't have to hand-wire them yourself. main character energy, minimal effort, iconic behavior 👑

ngl, if you're looking for options or flags — there aren't any 💀 this is a macro, not a command. no arguments, no environment variables, no exit statuses, nothing. just vibes and a struct getting initialized 🫶

🎀 SEE ALSO 🎀

• ./include/drm/drm_vblank_helper.h — the kernel file where this lives, go read it iykyk 📖
• DRM_CRTC_VBLANK_TIMER_FUNCS(9) — her sister page, the timer-based version of the same energy 🧚

and that's the whole page bestie!! 🌈💖

sign-off time 🫶 this little gem comes to you from the source path ./include/drm, dated October 2026, and she's part of the Kernel API Manual ✨ mwah, go initialize some structs 💋🎀
