sbi_set_timer(9)

💅 sbi_set_timer(9) — Kernel API Manual, section 9 🎀

okay bestie so you found yourself in the RISC-V corner of the kernel, and this little icon right here is sbi_set_timer — literally the function that tells the timer when the next timer event should pop off ✨

---

🌸 NAME 🌸

sbi_set_timer — program the timer for the next timer event, no cap 💖

Like, that's her whole job. She sets the timer. She does it well. Periodt.

---

✨ SYNOPSIS ✨

void sbi_set_timer (uint64_t stime_value );

that's it, that's the whole vibe 🦋 void return, one argument, she's not complicated and we love that for her.

---

🎀 ARGUMENTS 🎀

• stime_value — the value after which the next timer event should fire 🔥 basically "hey bestie, once we hit this point, do the thing." That's the moment. That's the deadline. Don't sleep on it 💅

---

⭐ RETURN ⭐

None. She returns nothing. Not a value, not a vibe check, nothing 🫶 void means void, and honestly? Iconic. No notes.

lowkey reminder bestie: the only thing this function takes is stime_value, and the only thing it gives back is nothing. That's the entire deal. Don't overthink her 🧚
