drm_client_dev_hotplug(9)

💅 drm_client_dev_hotplug(9)

okay so welcome to the Kernel API Manual bestie, this one's a little function with big main-character energy — it's the one that goes "hey everyone, something changed, look at the screen again" 🖥️✨

---

🌸 NAME 🌸

drm_client_dev_hotplug — send a hotplug event to clients, fr fr that's the whole vibe

---

✨ SYNOPSIS ✨

void drm_client_dev_hotplug (struct drm_device *dev );

---

🎀 ARGUMENTS 🎀

• dev — the DRM device 👑 (that's the DRM device, bestie, literally it)

---

💖 DESCRIPTION 💖

so what this does: it calls the drm_client_funcs.hotplug callback on all the clients that are attached. that's it, that's the function. it's giving "group chat announcement" 📣🦋

and here's the part where you can chill: drm_kms_helper_hotplug_event calls this function for you, so if your driver uses drm_kms_helper_hotplug_event, you don't need to call this one yourself. no cap, you're covered 🫶

🔥 SEE ALSO 🔥

• kernel file ./drivers/gpu/drm/drm_client_event.c 👀
• drm_client_dev_unregister(9)

ok that's the whole page, go touch grass (after you check your callbacks) 🌈🌱

later, bestie 💜 — this cutie came out of ./drivers/gpu/drm, dated October 2026, slay ✨🎀
