okay bestie, welcome to the Kernel API Manual page for dce_v8_0_hpd_init — it's the hpd setup callback, and yes it's giving "small function, important job" energy. 🫶

✨ NAME ✨

🌸 SYNOPSIS 🌸

void dce_v8_0_hpd_init (struct amdgpu_device *adev );

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. That's the one and only argument, bestie. 💅

So this function sets up the hpd pins used by the card (evergreen+). Iconic. It enables the pin, sets the polarity, and enables the hpd interrupts. That's the whole vibe — pin on, polarity set, hpd interrupts enabled. ✨
