xe_vm_add_fault_entry_pf(9)

✨ xe_vm_add_fault_entry_pf(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's a lil function from the xe driver crew, and she's honestly serving quiet-helper energy. let's get into it 🫶

---

💖 NAME 💖

xe_vm_add_fault_entry_pf — literally just "add pagefault to vm fault list", that's the whole vibe 💫

---

🌸 SYNOPSIS 🌸

void xe_vm_add_fault_entry_pf (struct xe_vm *vm , struct xe_pagefault
*pf );

no return value, no drama, she's a void girlie 😌

---

🎀 ARGUMENTS 🎀

• vm — the VM. yes. THE VM. the whole entire vibe container 🫶
• pf — the pagefault. the lil guy we're moving into the list ✨

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: this function takes the data from the pagefault pf and saves it to vm->faults.list. that's it, that's the job, and she does it flawlessly 💅

but bestie, there are two little caveats and you gotta know them, no cap ⚠️

• if the list is full, the function exits silently. like, no warning, no note, just poof 🫥 gone. she doesn't make a scene.
• if the pagefault could not be saved to the list, she reports a warning. so at least you get some signal if things went sideways 😭

fr fr, the "silent exit when full" thing is the icon we need to remember — it's lowkey giving "no thoughts, head empty" and you will NOT get a complaint from the kernel about it 💀
