💅 mipi_dsi_dc...htness_large(9) ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — yes that's the manual name, and yes this page is a whole vibe. It's all about mipi_dsi_dcs_set_display_brightness_large, which (spoiler) sets the 16-bit brightness value of the display. big screen energy ✨

---

🌸 NAME 🌸

mipi_dsi_dcs_set_display_brightness_large — sets the 16-bit brightness value of the display 💡

---

🦋 SYNOPSIS 🦋

int mipi_dsi_dcs_set_display_brightness_large (struct mipi_dsi_device
       *dsi , u16 brightness );

---

🎀 ARGUMENTS 🎀

• dsi — the DSI peripheral device 🫶 like, the screen's whole identity tbh
• brightness — the brightness value ✨ the actual number, the moment

---

💖 RETURN 💖

You get 0 on success 🥳 or a negative error code on failure 😭 (not me getting a negative error code 💀).

ngl if it returns negative, something lowkey went wrong. no cap.

and that's the whole page bestie, you ate that 🍓💜

sign-off era: this lil icon lives in ./drivers/gpu/drm, dated October 2026, in the Kernel API Manual 💫 iykyk — go forth and set that 16-bit brightness like the main character you are 👑🌈
