drm_self_re..._alter_state(9)

✨ NAME ✨

drm_self_refresh_helper_alter_state — bestie, this one alters the atomic state for SR exit 💅

(also yes, the manual is named drm_self_re..._alter_state(9) because the full name simply would not fit and the kernel is dramatic like that)

---

🌸 SYNOPSIS 🌸

void drm_self_refresh_helper_alter_state (struct drm_atomic_commit
*state );

---

🎀 ARGUMENTS 🎀

• state — the state currently being checked 👀 like, the atomic commit state we're looking at right now, that's the one

---

🦋 DESCRIPTION 🦋

okay so picture this: this function gets called at the end of atomic check. It goes through the state, looks for flags that are incompatible with self refresh exit, and changes them. That's the whole vibe check right there.

And yeah, ngl, it's a bit disingenuous 😭 — like, userspace is expecting one thing and we're giving it another. Kinda shady! But the reason is legit: to keep self refresh entirely hidden from userspace, this is required. No cap, it's literally mandatory. Periodt.

Then at the end, we queue up the self refresh entry work so we can enter PSR after the desired delay ✨ (PSR = panel self refresh, iykyk, and it enters after the delay you wanted, not before, we're not animals)

💀 friendly reminder from the manpage: this function will change your flags. That's not a bug, that's the assignment. It's giving "trust me bestie" energy.
