✨ mipi_dsi_dcs_set_tear_on(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a little function that turns on the display module's Tearing Effect output signal on the TE signal line. yes, that's a lot of capital letters, we'll get through it together 🫶

---

🌸 NAME 🌸

mipi_dsi_dcs_set_tear_on — turn on the display module's Tearing Effect output signal on the TE signal line. that's the whole vibe ✨

---

🎀 SYNOPSIS 🎀

int mipi_dsi_dcs_set_tear_on (struct mipi_dsi_device *dsi , enum
mipi_dsi_dcs_tear_mode mode );

like, it takes two things and gives you back an int, slay 💅

---

🦋 ARGUMENTS 🦋

• dsi — the DSI peripheral device. that's your main character right there 👑
• mode — the Tearing Effect Output Line mode. yep, that's the whole description, ngl it's giving minimal 🌈

---

💜 DESCRIPTION 💜

okay so this is the part where i have to be the bearer of bad news 😭 this function is deprecated. not "deprecated but i'll still use it" deprecated — like, actually deprecated. please use mipi_dsi_dcs_set_tear_on_multi instead, bestie, i'm literally begging 🥺 the newer one ate and left no crumbs.

fr fr, don't build anything new on this one. it's giving legacy support energy 💀

---

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code on failure 😭

that's it, that's the whole return value situation. no cap.

and that's the page!! mwah 💖 this one lives in ./drivers/gpu/drm, and the manual's dated October 2026, brought to you by the mipi_dsi_dcs_set_tear_on(9) page itself. go forth and use the _multi version, bestie — i believe in you 🫶✨🎀
