dc_get_det_...e_from_state(9)

🎀 dc_get_det_...e_from_state(9) 🎀

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're fancy now 💅 — and this page is all about one tiny little function that's honestly serving quiet-luxury main character energy. It doesn't do a lot, but what it does it does flawlessly. Let's get into it 💖

---

✨ NAME ✨

dc_get_det_buffer_size_from_state — the function that extracts the detile buffer size from dc state. That's it. That's the whole job. Iconic unproblematic behavior honestly 🧚

---

🌸 SYNOPSIS 🌸

unsigned int dc_get_det_buffer_size_from_state (const struct dc_state
*context );

that's the whole signature, and yes it's unsigned int that comes back at you, no cap.

---

🦋 ARGUMENTS 🦋

• context — a pointer to the dc_state from which the detile buffer size is extracted. like, it hands you a state and you're grabbing the detile buffer size out of it. that's the vibe check. 🫶

---

💜 DESCRIPTION 💜

so the way that this works is: this function is called to log the detile buffer size from the dc_state. literally that's the description, it's giving "she's a logger" and we respect it 😭✨

no hidden lore, no twist, no side quests. she logs. she slays. periodt.

---

🔥 RETURN 🔥

she returns the size of the detile buffer 💖 — or 0 if it's not available. like if there's no info, you get a 0, and honestly super fair of her, respecting boundaries fr fr.

okay bestie that's the whole page!! 💖 one last thing for the receipts: this beauty lives in ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — mark your calendars, she's a libra (probably) 🎀✨🦋 love u, go log ur buffers responsibly 🫶👑
