🌸 xe_guc_buf_cache_init_with_size(9) 🌸

okay so bestie, welcome to the Kernel API Manual — aka the xe_guc_buf_...it_with_size(9) page, yes the name got cut off, she's mysterious like that 💅. This is the glow-up version of the GuC Buffer Cache initializer, and honestly? She ate. Let's get into it 🎀

✨ NAME ✨

xe_guc_buf_cache_init_with_size — literally just "Initialize the GuC Buffer Cache." but make it custom-sized, iykyk 🦋

---

⭐ SYNOPSIS ⭐

here's the vibe check, no cap:

int xe_guc_buf_cache_init_with_size (struct xe_guc_buf_cache *cache ,
u32 size );

---

🫶 ARGUMENTS 🫶

• cache — the xe_guc_buf_cache you're initializing. she's the main character here 👑
• size — the size, in bytes. yes bestie, bytes, we're not out here guessing units 🙈

---

💖 DESCRIPTION 💖

So it's giving xe_guc_buf_cache_init, right? Like, same energy, same family. except — and this is the iconic part — it lets the caller make the cache buffer larger, so you can fit larger objects in there. bigger buffer, bigger possibilities, periodt ✨🔥

---

🌈 RETURN 🌈

• 0 on success 💜
• or a negative error code on failure 😭 (it happens, we recover, we move on)
