intel_psr_dc5_dc6_wa_init(9)

💅 intel_psr_dc5_dc6_wa_init 💅

okay bestie, welcome to the intel_psr_dc5_dc6_wa_init(9) page from the Kernel API Manual — yes that's the whole title, no cap, we're doing this ✨

---

🌸 NAME 🌸

intel_psr_dc5_dc6_wa_init — literally the "init work for underrun on idle PSR HW bug wa" situation 🫶

---

✨ SYNOPSIS ✨

void intel_psr_dc5_dc6_wa_init (struct intel_display *display );

That's it. That's the whole vibe. One function, one argument, zero drama (well, some drama, it's a hardware workaround 💀).

---

🎀 ARGUMENTS 🎀

• display — the intel atomic state 👑 (yes, that's exactly what the page says, so that's what you get, iykyk)

---

🦋 DESCRIPTION 🦋

So like. This one is targeted for the underrun on idle PSR HW bug — and it's got an official name, bestie: Wa_16025596647 🫠 iconic in the worst way.

What it does is init psr_dc5_dc6_wa_work, and that work is what actually applies the workaround. So this function is the setup girlie, not the one doing the labor. She just makes sure the work exists so it can get done ✨ periodt.
