💖 gaudi2_init_protection_bits(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a kernel function page, and ngl it's a short one but it's lowkey important so stay with me 🫶

---

🌸 NAME 🌸

gaudi2_init_protection_bits — literally just initializes the protection bits of specific registers 💅 no cap, that's the whole gig

---

✨ SYNOPSIS ✨

int gaudi2_init_protection_bits (struct hl_device *hdev );

like, it returns an int and takes exactly one thing, that's it, that's the vibe 🎀

---

🦋 ARGUMENTS 🦋

• hdev — pointer to hl_device structure. yep, just a pointer to the hl_device struct, hand it over and let the function cook 🔥

---

👑 DESCRIPTION 👑

okay so here's the tea ☕ — all protection bits are 1 by default, and that means not protected. periodt.

so what does this function actually do? it goes through and sets to 0 each bit that belongs to a protected register 🧚 like, every single bit that needs protecting gets flipped to 0, one by one. the way that this is literally the whole job 😭

bestie pls internalize this: 1 = not protected (the default), 0 = protected. don't mix them up or it's giving chaos 💀
