mipi_dsi_dcs_get_power_mode(9)

💅 mipi_dsi_dcs_get_power_mode(9) — from the Kernel API Manual, bestie

okay so first of all, yes, this is a real function in the Kernel API Manual, and it's lowkey one of the cutest little helpers because all it does is ask the display how it's doing. 🫶

✨ NAME ✨

mipi_dsi_dcs_get_power_mode — query the display module's current power mode. that's it, that's the whole vibe: we're checking what power state the display is in rn. 💅

---

🌸 SYNOPSIS 🌸

int mipi_dsi_dcs_get_power_mode (struct mipi_dsi_device *dsi , u8 *mode );

like, you hand it a device, you hand it somewhere to stash the answer, and it goes and gets the tea. ☕

---

🎀 ARGUMENTS 🎀

• dsi — the DSI peripheral device. this is the display bestie we're interrogating, main character of the whole call. 👑
• mode — return location for the current power mode. it's a u8 *, and it's where the answer gets dropped off — so yeah, that pointer needs to be somewhere valid to write to, mmkay? 🍓

---

⭐ RETURN ⭐

0 on success — slay, it worked, the mode is chilling in *mode now. ✨

Or a negative error code on failure — so like, anything less than zero means something went sideways and no, you can't just ignore it. 😭
