💅 msm_disp_snapshot_state_sync — the kernel API manual, bestie edition 🎀

okay so before we even start — hi, this is from the Kernel API Manual, and it's about msm_disp_snapshot_state_sync. yes the function name is a whole mouthful, we're gonna get through it together, i promise 🫶

---

✨ NAME ✨

msm_disp_snapshot_state_sync — grab a snapshot of the display state, synchronously. like, you wait for it. no "i'll text you later" energy, we're doing this now 💅

---

🌸 SYNOPSIS 🌸

struct msm_disp_state * msm_disp_snapshot_state_sync (struct msm_kms
*kms );

it hands you back a struct msm_disp_state * and it takes exactly one thing. so iconic, so simple 🌟

---

🦋 ARGUMENTS 🦋

• kms — the kms object. that's it. that's the whole list. she's low maintenance 💖

---

⭐ RETURN ⭐

returns state — or an error. so like, either you get your little snapshot struct, or you get a "nope" 😭 that's the whole vibe check.

---

🧚 CONTEXT 🧚

okay this part is so important, do not skip it, i'm serious:

must be called with kms->dump_mutex held 🔒

like literally do not call this without holding that mutex, that's the rule, that's the assignment, periodt 👑
