mipi_dsi_dcs_set_display_on(9)

💖 mipi_dsi_dcs_set_display_on(9) 💖

okay bestie, so this is a page from the Kernel API Manual, and it's all about mipi_dsi_dcs_set_display_on — the li'l function that tells your display to actually, y'know, start showing the image data. iconic behavior honestly.

✨ NAME ✨

mipi_dsi_dcs_set_display_on — start displaying the image data on the display device 🖼️✨

🎀 SYNOPSIS 🎀

int mipi_dsi_dcs_set_display_on (struct mipi_dsi_device *dsi );

💅 ARGUMENTS 💅

• dsi — the DSI peripheral device. that's your main character right there 💜

🦋 DESCRIPTION 🦋

okay so listen. this function is deprecated 😭 — like, it still exists, but it's giving "we don't really use this anymore." instead, use mipi_dsi_dcs_set_display_on_multi instead. no cap, just switch over, it's the glow-up version 🔥

ngl deprecated stuff still works but pls don't build new things on it, bestie 🫶

🌸 RETURN 🌸

0 on success, or a negative error code on failure. that's it, that's the whole mood 💀
