intel_psr_init(9)

💅 intel_psr_init(9) — Kernel API Manual, bestie edition 🎀

okay so this is from the intel_psr_init(9) page in the Kernel API Manual and it's literally all about getting your PSR basics set up before anything cute can happen. let's get into it ✨

---

✨ NAME ✨

intel_psr_init — init the basic PSR work and the mutex, and yes that's the whole vibe 🫶

---

🌸 SYNOPSIS 🌸

void intel_psr_init (struct intel_dp *intel_dp );

no return value, it just does the thing, periodt 💅

---

🦋 ARGUMENTS 🦋

• intel_dp — the Intel DP. that's it, that's the argument (Intel DP, iconic, no notes) 💖

---

⭐ DESCRIPTION ⭐

so here's the tea: this function gets called after the initializing connector. and real quick, in case you were wondering what that connector-initializing situation is doing — it's treating the handling of connector capabilities. iykyk 🧚

and then, for each DP Encoder, it initializes the basic PSR stuff. that's the whole job. it's giving setup energy, it's giving behind-the-scenes main character, and honestly? we love that for it 🌈

lowkey important: this page ships out of ./drivers/gpu/drm/i915/display, dated October 2026, and it's intel_psr_init(9) all day every day 💜

okay that's the page, mwah, go init some PSR 💅✨🦋
