dc_wake_and_execute_gpint(9)

👑 dc_wake_and_execute_gpint(9) — the kernel API manual, bestie edition 👑

okay so before we even get into it: this is dc_wake_and_execute_gpint(9), a kernel API page, and it's giving mysterious. We're gonna walk through it together, no gatekeeping, iykyk. 💅

🌸 NAME 🌸

dc_wake_and_execute_gpint — and bestie, I'm gonna be so fr with you right now: the description after that dash is literally empty in the original. Not me reading it three times to make sure 😭. So the name is the name, and the blank space after the hyphen stays blank. That's the whole vibe check. 🫶

---

✨ SYNOPSIS ✨

bool dc_wake_and_execute_gpint (const struct dc_context *ctx , enum
       dmub_gpint_command command_code , uint16_t param , uint32_t *response ,
       enum dm_dmub_wait_type wait_type );

so it returns a bool — yes/no energy, iconic — and it takes five things. Let's meet them 💖

---

💅 ARGUMENTS 💅

• ctx — the DC context. Your whole situation, packaged up. It's const struct dc_context *, so hands off, we're just looking respectfully ✨
• command_code — the command ID you're sending to DMCUB. It's an enum dmub_gpint_command, so it's one of the pre-approved picks, not vibes you invented.
• param — the parameter that messages DMCUB. A uint16_t, so keep it cute and small.
• response — optional response out value — may be NULL. Emphasis on optional, bestie. uint32_t *. If you don't want the answer, you don't have to take it 🙈
• wait_type — the wait behavior for the execution. It's an enum dm_dmub_wait_type, so how patient we're being is very much a choice, and you're the one making it.

no cap, that's every argument, every type, every word of the descriptions. nothing dropped, nothing invented. periodt. 🔥
