STRUCT MODE_SELECTION(9)

🌈 struct mode_selection — Kernel API Manual 💅

okay so bestie, welcome to the iconic little struct that manages the selection and state of Alternate Modes ✨. yes, that's its whole job. it's giving "I keep the Alt Modes in line" main character energy, and honestly? it ate.

✨ NAME ✨

struct mode_selection — Manages the selection and state of Alternate Modes 🦋

🎀 SYNOPSIS 🎀

struct mode_selection {
    struct list_head mode_list;
    struct mutex lock;
    struct delayed_work work;

    u16 active_svid;
    unsigned int timeout;
    unsigned int delay;
 };

like, that's the whole thing. seven members. no cap. 🌸

💖 Members 💖

okay so here's the member-by-member breakdown, and yes I'm gonna hype each one because they all matter fr fr:

• mode_list — Prioritized list of available Alternate Modes 👑 the order here is literally the priority, so don't be messy with it.
• lock — Mutex to protect mode_list 🔒 yes bestie, protect it. concurrent access is not the vibe.
• work — Work structure ⚙️
• partner — Handle to the Type-C partner device 🫶
• active_svid — svid of currently active mode 🏷️
• timeout — Timeout for a mode entry attempt, ms ⏳ (milliseconds, so like, don't blink)
• delay — Delay between mode entry/exit attempts, ms 🕐 (also milliseconds — pacing is everything, periodt)

like, go read those too, iykyk 💅

lowkey reminder bestie: this is kernel API territory — read the actual source before you go poking mode_list without holding lock, okay? 🙈
