amdgpu_dm_mo...date_streams(9)

✨ amdgpu_dm_mod_power_update_streams(9) ✨

okay bestie, welcome to the Kernel API Manual — this one's a little function with a big job, and yes the page title got chopped by the terminal (amdgpu_dm_mo...date_streams(9), iconic truncation energy 💅) but we move.

---

🌸 NAME 🌸

amdgpu_dm_mod_power_update_streams — updates the mod_power stream state whenever a modeset happens 🎀

---

🦋 SYNOPSIS 🦋

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

like. that's the whole signature. no return value, she just does things 💫

---

💖 ARGUMENTS 💖

• state — the drm atomic state, aka the whole current vibe of what's being committed ✨
• dm — the display manager that we're updating mod_power on 🫶

---

👑 DESCRIPTION 👑

so here's the tea ☕ — this function notifies mod_power about stream changes on modeset events, and it also disables PSR/Replay to get everything prepped for hardware programming. think of it as clearing the runway before the plane lands, no cap 🔥

and if you wanna see the after party, check out amdgpu_dm_mod_power_setup_streams — that's the post-modeset mod_power setup, the sequel to this main character moment 🌈

fr fr, this is the "before hardware programming" step — remember it disables PSR/Replay, so don't be surprised when that happens 👀
