💅 dprc_remove_devices(9) — like, the Kernel API Manual one 🎀

okay so bestie, welcome to page dprc_remove_devices(9) of the Kernel API Manual ✨ this is the whole vibe, let's go 🦋

🌸 NAME 🌸

dprc_remove_devices — removes devices for objects that got yeeted out of a DPRC 💀✨

---

⭐ SYNOPSIS ⭐

void dprc_remove_devices (struct fsl_mc_device *mc_bus_dev , struct
fsl_mc_obj_desc *obj_desc_array , int num_child_objects_in_mc );

(no cap, that weird space before the commas is literally how it's written, we do not touch it 🙈)

---

🧚 ARGUMENTS 🧚

• mc_bus_dev — a pointer to the fsl-mc device that represents a DPRC object 🫶 like, this is the main character of the call.
• obj_desc_array — the array of object descriptors for the child objects that are currently present in the DPRC in the MC 👑
• num_child_objects_in_mc — the number of entries in obj_desc_array, i.e. how many of the above you're actually handing over 🍓

---

💖 DESCRIPTION 💖

So here's the tea ☕: this function synchronizes the state of the Linux bus driver with the actual state of the MC 💅 it does that by removing the devices that represent MC objects which have been dynamically removed in the physical DPRC.

tl;dr — the MC was like "these objects? gone." and this function is what makes the Linux side agree ✨ lowkey iconic behaviour, ngl 😭
