mmhub_v1_8_...able_default(9)

💅 mmhub_v1_8_...able_default(9) — Kernel API Manual, section 9 ✨

Okay so bestie, welcome to the GPU corner of the kernel 🫶 this one is a little function from the amdgpu driver and honestly? It's giving "small but iconic." Let's get into it.

---

✨ NAME ✨

mmhub_v1_8_set_fault_enable_default — the function that updates GART/VM fault handling 😤 no cap, that's literally its whole job.

---

🎀 SYNOPSIS 🎀

void mmhub_v1_8_set_fault_enable_default (struct amdgpu_device *adev ,
bool value );

Look at that signature, she's serving void realness — nothing comes back, she just does the thing and leaves 💅

---

🌸 ARGUMENTS 🌸

• adev — an amdgpu_device pointer. That's your GPU's whole personality in a struct, yup 💖
• value — a bool, and here's the tea: true redirects VM faults to the default page. That's it, that's the whole switch 🦋

Lowkey important: the only behaviour described for value is that true redirects VM faults to the default page. Don't go inventing what false does, bestie — the page doesn't say, and we don't make things up here 🙈
