xe_guc_ct_stop(9)

💅 xe_guc_ct_stop(9) 💅

okay so real talk, this is a page straight out of the Kernel API Manual — yeah, the big official one — and it's about xe_guc_ct_stop. buckle up bestie, it's short but it's important 🫶

✨ NAME ✨

xe_guc_ct_stop — set GuC to stopped state 👑

✨ SYNOPSIS ✨

void xe_guc_ct_stop (struct xe_guc_ct *ct );

✨ ARGUMENTS ✨

• ct — the xe_guc_ct, aka the vibe in question. it's the GuC CT struct, literally the whole point 🎀

✨ DESCRIPTION ✨

so what does it do?? it sets the GuC CT to stopped state, stops the g2h handler, and clears any outstanding g2h 💅

that's it. that's the whole function. no cap, it's giving "clean shutdown, main character energy" — everything gets halted and nothing gets left dangling 🌸

heads up: this is the stop move, so treat it like actually stopping things — the g2h handler goes down and outstanding g2h gets cleared out. don't expect anything to keep flowing after this ✨
