xe_guc_tlb_inval_init_early(9)

✨ xe_guc_tlb_inval_init_early ✨

Okay bestie, so we're in the kernel API manual (section 9, the fun one 💅) and today's main character is xe_guc_tlb_inval_init_early — the lil setup function that gets GuC TLB invalidation ready early. No cap.

---

🌸 SYNOPSIS 🌸

void xe_guc_tlb_inval_init_early (struct xe_guc *guc , struct
       xe_tlb_inval *tlb_inval );

It returns void, it takes two args, and it's giving "small function, big responsibility". 🫶

---

🎀 ARGUMENTS 🎀

• guc — the GuC object. Your GuC. The one and only. 👑
• tlb_inval — the TLB invalidation client. She's the one getting set up. ✨

---

💖 DESCRIPTION 💖

So what does it actually do? It initializes GuC TLB invalidation by doing two things, and honestly? Both slay:

1. Setting the back pointer in the TLB invalidation client so it points back to the GuC. 🔙
2. Setting the GuC backend ops. ⚙️

That's it, that's the function. Lowkey simple, highkey essential. Like literally, "init early" is right there in the name — she's not waiting around. 🦋

No return value, no error path, no drama. She just does the thing and dips. 💀
