🌟 vpif_output_to_subdev(9) 🌟

okay so welcome to the vpif_output_to_subdev(9) page from the Kernel API Manual, bestie. this is the little function that maps an output to a sub device, and we're gonna get into all of it. no cap.

---

🌸 NAME 🌸

vpif_output_to_subdev — Maps output to sub device. that's the whole vibe: it maps an output to a sub device. periodt.

---

✨ SYNOPSIS ✨

int vpif_output_to_subdev (struct vpif_display_config *vpif_cfg , struct
       vpif_display_chan_config *chan_cfg , int index );

it returns an int, and it takes the config pointers plus an index. iconic signature behavior.

---

🎀 ARGUMENTS 🎀

• vpif_cfg — global config ptr. literally the global config pointer, aka the big-picture config situation.
• chan_cfg — channel config ptr. the channel config pointer, right there for the channel.
• index — Given output index from application. the output index the application handed over, exactly like it sounds.

---

💅 DESCRIPTION 💅

okay so here's the tea: this does a lookup of the sub device information for a given output index. we report all the output to application. the output table also has the sub device name for the each output. that's the whole flow, bestie — lookup, report, and the table carries the sub device name for the each output. no extra lore, no invented behavior, just the facts with a little sparkle. 💖
