i3c_device_enable_ibi(9)

🌸 i3c_device_enable_ibi — NAME ✨

okay so bestie, this page is from the Kernel API Manual and it's about i3c_device_enable_ibi — the function that enables IBIs coming from a specific device. that's the whole vibe. 💅

---

🦋 SYNOPSIS

int i3c_device_enable_ibi (struct i3c_device *dev );

---

🎀 ARGUMENTS

• dev — the device on which IBIs should be enabled. that's it, that's the one argument, she's lowkey simple like that 🫶

---

💖 DESCRIPTION

so what this function does is, like, enable IBIs coming from a specific device, and then it waits for all pending IBIs to be processed. no cap, it actually waits. main character energy: it does not return until the pending stuff is handled. ✨

highkey important: you should call this on a device where i3c_device_request_ibi has succeeded. like, don't just roll up on a random device, it's giving "read the prerequisites first" 🙈

⚠️ also heads up: IBIs from this device might be received before this function returns to its caller. so don't be shook if that happens — the page said so, i'm just the messenger. 😭

---

🌈 RETURN

0 in case of success, a negative error core otherwise. (yes, "core" — that's literally what the page says, i'm not fixing it, i'm just quoting the icon 💀)
