✨ ps3_enable_spu ✨

okay so bestie, welcome to the ps3_enable_spu(9) page — it's a kernel API manual entry and it's literally all about turning on SPU run control 🎀

---

🌸 NAME 🌸

ps3_enable_spu — Enable SPU run control 💅

---

🦋 SYNOPSIS 🦋

void ps3_enable_spu (struct spu_context *ctx );

---

🍓 ARGUMENTS 🍓

• ctx — ngl the original page just says -- undescribed -- 😭 so yeah, no description here, that's genuinely all we get 🙈

---

🌈 DESCRIPTION 🌈

okay so the vibe here is that there's this outstanding enhancement for the PS3 — like, a glow-up that hasn't happened yet, iykyk ✨ — and it would be to add a guard to check for incorrect access to the spu problem state when the spu context is disabled 👑

the way this check would work: it could be implemented with a flag added to the spu context that would inhibit mapping problem state pages, plus a routine to unmap spu problem state pages 🫶

so when the spu is enabled with ps3_enable_spu, the flag would be set, allowing pages to be mapped 💖 and when the spu is disabled with ps3_disable_spu, the flag would be cleared and the mapped problem state pages would be unmapped 💀 periodt, that's the whole plan.

fr fr this is described as an enhancement that's still outstanding — so don't go thinking it's already guarding anything, bestie 😭
