mipi_dsi_dcs..._display_off(9)

💅 mipi_dsi_dcs..._display_off(9) — from the Kernel API Manual, bestie ✨

okay so bestie, gather round, because we're reading a kernel manpage together and honestly? it's giving ✨niche display-driver lore✨. welcome to the Kernel API Manual, section 9, and the page is mipi_dsi_dcs..._display_off(9) — yes the title has an ellipsis in it, no that's not me being dramatic, that's literally how it's printed. 🎀

---

🦋 NAME 🦋

mipi_dsi_dcs_set_display_off — the function that stops the display device from showing the image data. like, it tells the screen "bestie, stop displaying, we're done here" 💅

---

🌸 SYNOPSIS 🌸

int mipi_dsi_dcs_set_display_off (struct mipi_dsi_device *dsi );

literally one argument, one int coming back. clean. minimal. iconic. ✨

---

🎀 ARGUMENTS 🎀

• dsi — the DSI peripheral device. that's the screen you're talking to, your main character display 🫶

---

🔥 DESCRIPTION 🔥

so here's the tea 😭 — this function is deprecated. like, not "kinda old", not "legacy-ish", deprecated deprecated. the manpage says it flat out.

instead, you use mipi_dsi_dcs_set_display_off_multi — that's the glow-up version, the one you're actually supposed to be calling. no cap. 🧚

🩷 so yeah, if you're writing new code and you reach for mipi_dsi_dcs_set_display_off, put it down gently and go find the _multi one instead. the kernel said what it said.

---

⭐ RETURN ⭐

• 0 on success — yay, slayed, display off achievement unlocked 👑
• a negative error code on failure — nope, didn't work, the vibe check failed 😭
