mipi_dsi_compression_mode(9)

🌸 mipi_dsi_compression_mode(9) 🌸

okay so bestie, we're in the Kernel API Manual today and this one is literally about flipping Display Stream Compression on and off on a DSI peripheral. it's giving "one job, does it well" energy and honestly? we love a focused icon. 💅

---

✨ SYNOPSIS ✨

int mipi_dsi_compression_mode (struct mipi_dsi_device *dsi , bool enable
);

like, that's the whole vibe. two args, one return, no drama. 🎀

---

🦋 ARGUMENTS 🦋

• dsi — the DSI peripheral device in question, your main character of the moment 💖
• enable — a bool that says whether you're turning the DSC on or off. yes or no. slay or not slay. 🫶

---

👑 DESCRIPTION 👑

So here's the tea: this function enables or disables Display Stream Compression on the peripheral. 🎀

and the way it does it — no cap — is with the default Picture Parameter Set and the VESA DSC 1.1 algorithm. that's it, that's the whole bit. you don't get to pick a fancy custom parameter set here, bestie; that's what the defaults are for. 🌈

---

⭐ RETURN ⭐

• 0 on success 💯 (iconic, flawless, no notes)
• a negative error code on failure 😭 (the vibe check failed, go read your errno)

🧚 SEE ALSO 🧚

okay this list is long long, but every single one of these is part of the family so we're listing them all, periodt. 🔥

quick reminder bestie: this is kernel API territory, so always check that return value. a negative number is not a cute aesthetic, it's an error. 🙈

and that's the page!! it lives over in ./drivers/gpu/drm, dated October 2026, and it's filed under mipi_dsi_compression_mode(9) in your Kernel API Manual. go be gorgeous with your compression settings, mwah 💋🌸✨
