💅 amdgpu_dm_mod_power_setup_streams(9) — the glow-up

okay so bestie, welcome to the Kernel API Manual ✨ this one's a function page from the kernel docs, and honestly? she's short but she matters. Let's get into it 🫶

---

✨ NAME ✨

amdgpu_dm_mod_power_setup_streams — the girl who sets up the mod_power stream state after the modeset is done 💅 like, post-modeset cleanup era, no cap.

---

🌸 SYNOPSIS 🌸

void amdgpu_dm_mod_power_setup_streams (struct drm_atomic_commit *state
, struct amdgpu_display_manager *dm );

that's it. that's the whole signature. she takes two things and gives you nothing back (void, iconic, unbothered 👑).

---

🎀 ARGUMENTS 🎀

• state — the drm atomic state 🦋 like, the whole commit vibe you're working with.
• dm — the display manager you're updating mod_power on 💖 this is the main character she's operating on.

---

💜 DESCRIPTION 💜

so what she does is notify mod_power of mode_change. simple. but here's the tea ☕ — the timing matters, fr fr:

this needs to be done after the dc_stream updates have been committed, and after the VRR parameters have been updated. do it out of order and it's giving chaos 😭

so like: commit the streams → update VRR → then call this. order is everything, iykyk 🌈
