how and where is int_bottom invoked?

[john_12]

Hello,

I am following along a tutorial on operating systems and do not understand where in the code the "int_bottom" routine is invoked (it is written in interrupstubs.s).
Can someone tell me how/where it is invoked? Thanks!

this is the tutorial, the code is written first in commit number 5:
Files for part 5, https://www.youtube.com/watch?v=AgeX-U4dKSs * AlgorithMan-de/wyoos@01557ac * GitHub

you can go to commit number 5 by cloning this repository and executing
git checkout 01557ac3b68bc7f9e39e76d4b4bf2fdbe627ce3d to reset to commit number 5.
