dprc_remove(9)

💅 dprc_remove(9) — like, the DPRC unbind callback, bestie

okay so this is a page from the Kernel API Manual (yes, the kernel has lore too) and it's about dprc_remove — the callback that gets invoked when a DPRC is being unbound from this driver ✨

🌸 NAME 🌸

dprc_remove — callback invoked when a DPRC is being unbound from this driver

like literally it's the "you're leaving?? okay bye, let me tidy up" function 🫶

---

🎀 SYNOPSIS 🎀

void dprc_remove (struct fsl_mc_device *mc_dev );

that's it. that's the whole signature. no cap 💅

---

🦋 ARGUMENTS 🦋

• mc_dev — Pointer to fsl_mc_device representing the DPRC. it's giving "the whole device, in one pointer" 👑

---

🔥 DESCRIPTION 🔥

so when this gets called, here's the whole cleanup arc, main character energy only:

• It removes the DPRC's child objects from Linux — not from the MC, important distinction, don't mix that up 🙈
• It closes the DPRC device in the MC.
• It tears down the interrupts that were configured for the DPRC device ⚡
• It destroys the interrupt pool associated with this MC bus.

it's a full teardown, like when the group chat goes quiet and everyone logs off. iconic, honestly 💀✨
