xe_guc_ct_disable(9)

💅 xe_guc_ct_disable(9) — like, the Kernel API Manual, bestie ✨

okay so real talk, this is a page from the Kernel API Manual and it's about putting GuC into its disabled era. it's short, it's sweet, it's giving "one job and she does it." let's get into it 🎀

---

🌸 NAME 🌸

xe_guc_ct_disable — literally just sets GuC to the disabled state, no cap 💅

---

✨ SYNOPSIS ✨

void xe_guc_ct_disable (struct xe_guc_ct *ct );

that's it. that's the whole vibe. she returns void, she takes one pointer, she's lowkey iconic 🦋

---

🫶 ARGUMENTS 🫶

• ct — the xe_guc_ct, that's your girl, that's the one you're disabling 💖

---

🔥 DESCRIPTION 🔥

so what she does is: set the GuC CT to the disabled state, and stop the g2h handler. that's the whole assignment and she ate it fr fr.

and here's the important part — no outstanding g2h is expected in this transition. like, that's the assumption going in, okay? don't come for her with pending g2h business, that is not the vibe she signed up for 😭
