drm_kms_helper_poll_enable(9)

hiii bestie 💖 welcome to the drm_kms_helper_poll_enable(9) page from the Kernel API Manual — this is the little helper that wakes output polling back up after its nap, and honestly it's giving responsible-main-character energy ✨

---

🌸 NAME 🌸

drm_kms_helper_poll_enable — re-enable output polling. periodt 💅

---

🦋 SYNOPSIS 🦋

okay so the whole signature is literally this, no cap:

void drm_kms_helper_poll_enable (struct drm_device *dev );

---

🎀 ARGUMENTS 🎀

• dev — a drm_device. that's the whole argument list, bestie, we love a minimalist icon 🫶

---

💅 DESCRIPTION 💅

okay so this function re-enables the output polling work after it's been temporarily disabled using drm_kms_helper_poll_disable — think suspend/resume era, the little polling nap moment 😴✨

drivers can call this helper from their device resume implementation. and it is not an error to call this even when output polling isn't enabled — so like, no stress there, fr fr 💖

⚠️ but listen: if device polling was never initialized before, this call will trigger a warning and return. so don't come at it before init, iykyk 🙈

also note that calls to enable and disable polling must be strictly ordered — and that's automatically the case when they're only called from suspend/resume callbacks. keep it tidy, bestie, the vibes stay immaculate when the order stays immaculate 🌈
