okay so this is a page from the Kernel API Manual, bestie — yes, the real one, and yes, we're gonna get through it together because it's literally so short and so slay 🫶

💅 NAME 💅

xe_guc_comm_init_early — the early initialization of GuC communication, aka the little pre-game ritual before your driver actually starts talking to the firmware 🔥

---

🎀 SYNOPSIS 🎀

void xe_guc_comm_init_early (struct xe_guc *guc );

that's it. that's the whole signature. no return value, no drama. iconic behavior honestly 💜

---

🌸 ARGUMENTS 🌸

• guc — the xe_guc you're initializing, bestie. that's your main character right there 👑

---

🦋 DESCRIPTION 🦋

So like… this must be called prior to first MMIO communication with GuC firmware. periodt.

like, not "it'd be nice", not "whenever you get around to it" — must. before the very first MMIO chat with the GuC firmware, this function has already happened. no cap, that's the rule 🙈
