π i3c_device_free_ibi(9) β or, "how to clean up your IBI situation"
okay so this is a page from the Kernel API Manual (yes, the real one, section 9, kernel-space legends only π«Ά) and it's about the function i3c_device_free_ibi. Bestie, it's a cleanup function. It's the "take out the trash after the party" of I3C. Let's get into it β¨
πΈ NAME πΈ
i3c_device_free_ibi β frees, like, all the resources you need for IBI handling. every last one. no leftovers, no crumbs π
π¦ SYNOPSIS π¦
void i3c_device_free_ibi (struct i3c_device *dev );
that's it. one argument, returns nothing (void, she gives nothing back and that's iconic π).
π ARGUMENTS π
devβ the device on which you want to release the IBI resources. like, which device are we un-IBI-ing here. that one π
β¨ DESCRIPTION β¨
so, what does she actually do? this function is responsible for de-allocating resources previously allocated by i3c_device_request_ibi. think of i3c_device_request_ibi as the friend who books the venue, and i3c_device_free_ibi as the friend who actually cancels the booking afterwards (we love a responsible queen π).
β οΈ important vibe check: it should be called after disabling IBIs with i3c_device_disable_ibi. do not skip that step, bestie, the order matters fr fr π
so the whole flow is: request β enable β (do your thing) β disable β free. main character energy requires a proper ending π§
π SEE ALSO π
kernel file ./drivers/i3c/device.c, plus the whole friend group:

it's giving "found family of I3C helpers" and honestly? obsessed π
and that's the whole page!! this one came straight out of ./drivers/i3c, dated October 2026, from the Kernel API Manual β so go free those IBI resources, slay, and remember: disable before you free, always π«Άπ
