ENUM GPIO_V2_LINE_EVENT_ID(9)

💅 enum gpio_v2_line_event_id(9) — Kernel API Manual

okay so bestie, welcome to the manual page for enum gpio_v2_line_event_id. This is the kernel API manual, and this little guy is literally just the list of allowed values for &struct gpio_v2_line_event.id 🎀. That's it. That's the whole vibe. No cap.

---

✨ NAME ✨

enum gpio_v2_line_event_id — the values that go in &struct gpio_v2_line_event.id 🦋

---

🌸 SYNOPSIS 🌸

enum gpio_v2_line_event_id {
    GPIO_V2_LINE_EVENT_RISING_EDGE ,
    GPIO_V2_LINE_EVENT_FALLING_EDGE

};

look at her. two members. zero drama. iconic 💅

---

👑 Constants 👑

so there's exactly two of them and they're both about edges, which honestly makes sense for a GPIO line event, iykyk:

• GPIO_V2_LINE_EVENT_RISING_EDGE — this is the "event triggered by a rising edge" one 🔥 like the signal went up and the kernel is like "noted, bestie."
• GPIO_V2_LINE_EVENT_FALLING_EDGE — and this one is the "event triggered by a falling edge" one 🌈 signal goes down, event fires, we move.

that's the whole enum. two constants, both edge-coded, both slaying in their own lane ✨

🫶 SEE ALSO 🫶

okay this is the part where the kernel is like "and here's everyone else at the party" — the kernel file is ./include/uapi/linux/gpio.h, and it wants you to go hang out with:

• struct gpiochip_info(9)
• enum gpio_v2_line_flag(9)
• struct gpio_v2_line_values(9)
• enum gpio_v2_line_attr_id(9)
• struct gpio_v2_line_attribute(9)
• struct gpio_v2_line_config_attribute(9)
• struct gpio_v2_line_config(9)
• struct gpio_v2_line_request(9)
• struct gpio_v2_line_info(9)
• enum gpio_v2_line_changed_type(9)
• struct gpio_v2_line_info_changed(9)
• struct gpio_v2_line_event(9)
• struct gpioline_info(9)
• struct gpioline_info_changed(9)
• struct gpiohandle_request(9)
• struct gpiohandle_config(9)
• struct gpiohandle_data(9)
• struct gpioevent_request(9)
• struct gpioevent_data(9)

that's a whole group chat right there 😭 go read them all, fr fr. main character energy is struct gpio_v2_line_event(9) obviously but don't tell the others 💀

ngl if you're here just to find out which edge fired an event: it's one of the two constants above. rising or falling. that's the post 🧚

and that's a wrap, bestie!! this page came from ./include/uapi/linux, dated October 2026, and it's filed under enum gpio_v2_line_event_id(9). go forth and read your edges 💖✨🍓
