spu_activate(9)

💅 spu_activate(9) 💅

okay bestie, welcome to the spu_activate(9) page in the Kernel API Manual — this is the whole vibe: find a free spu for a context and execute it. 🫶

🌸 NAME 🌸

spu_activate — find a free spu for a context and execute it ✨

---

✨ SYNOPSIS ✨

int spu_activate (struct spu_context *ctx , unsigned long flags );

---

🎀 ARGUMENTS 🎀

• ctx — the spu context you wanna schedule, aka the thing that needs an spu. 💖
• flags — flags (currently ignored), so it's lowkey just along for the ride. 🙈

no cap, flags being ignored is literally in the manual — don't come for me. 💀

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: spu_activate() tries to find a free spu to run ctx. if there's a free spu available, slay. if no free spu is available, it adds the context to the runqueue so it gets woken up once an spu is available. that's it, that's the whole plot. 👑
