drm_dsc_flatness_det_thresh(9)

💅 drm_dsc_flatness_det_thresh(9) — from the Kernel API Manual, bestie

okay so bestie, listen — this one lives in the Kernel API Manual and it's honestly such a little icon. It's a kernel function that computes one specific number for you and then dips. Lowkey slay. ✨

🎀 NAME 🎀

drm_dsc_flatness_det_thresh — literally just calculates the flatness_det_thresh for the given DSC config. That's the whole gig. She's focused, she's main character energy, she does one thing. 🫶

---

🌸 SYNOPSIS 🌸

u32 drm_dsc_flatness_det_thresh (const struct drm_dsc_config *dsc );

That's it. That's the signature. Copy it exactly, no cap — u32 out, const struct drm_dsc_config * in. 🦋

---

✨ ARGUMENTS ✨

• dsc — pointer to the DRM DSC config struct. Yes bestie, a pointer, and it's const, so like… hands off, don't touch, we're just reading. 🙈

---

💖 RETURN 💖

It returns the calculated flatness det thresh value. That's the value. That's the vibe check result. 🔥

ngl the doc doesn't say anything else about it, so I'm not gonna sit here and invent lore. What it says is what you get. 💅
