✨ NAME ✨

oaktrail_restore_display_registers — the little function that puts your registers back after they ghosted you during suspend/resume 💅

okay so real talk, this is from the Kernel API Manual (yes we're reading kernel docs for fun now, that's the era we're in 👑) and honestly? she's short, she's sweet, she's doing one job and doing it well. no cap.

🌸 SYNOPSIS 🌸

int oaktrail_restore_display_registers (struct drm_device *dev );

that's it. that's the whole vibe. one function, one argument, returns an int 🎀

---

🦋 ARGUMENTS 🦋

• dev — our DRM device 💖 like, ours. the one we're working with. she's the main character here, everything happens to her.

---

🧚 DESCRIPTION 🧚

so picture this: your register state gets lost during suspend and resume 😭 tragic, I know. this function's whole purpose in life is to restore that lost register state. that's it, that's the job. she shows up, she puts the registers back where they belong, she leaves. iconic behaviour honestly 🌈

no extra lore here bestie — the manpage says "restore register state that was lost during suspend and resume" and we are NOT inventing details. periodt 💀
