xe_svm_handle_pagefault(9)

🌸 NAME 🌸

xe_svm_handle_pagefault — SVM handle page fault. Okay bestie, welcome to the xe_svm_handle_pagefault(9) page from the Kernel API Manual 💅✨

---

✨ SYNOPSIS ✨

Here's the signature, keep it cute and keep it exact 🫶

int xe_svm_handle_pagefault (struct xe_vm *vm , struct xe_vma *vma ,
struct xe_gt *gt , u64 fault_addr , bool atomic );

---

💅 ARGUMENTS 💅

• vm — the VM, bestie.
• vma — the CPU address mirror VMA.
• gt — the gt where the fault occurred.
• fault_addr — the GPU fault address.
• atomic — the fault atomic access bit.

---

🦋 DESCRIPTION 🦋

So what's the vibe? It creates GPU bindings for an SVM page fault. Optionally, it migrates to device memory. That's the whole little mission, no cap 💖

---

🎀 RETURN 🎀

Returns 0 on success, and a negative error code on error. No in-between, periodt 💀✨
