spu_save(9)

💾 spu_save(9) — the "save ur SPU context, but make it thread-safe" era

okay bestie, welcome to the Kernel API Manual ✨ this one's a little function from the Cell SPU filesystem world and it is, genuinely, the most polite little thing: it locks, it saves, it returns. no drama, no cap. 🎀

---

✨ NAME ✨

spu_save — SPU context save, but like… with locking. 🔒💅

---

🌸 SYNOPSIS 🌸

int spu_save (struct spu_state *prev , struct spu *spu );

---

🦋 ARGUMENTS 🦋

• prev — pointer to the SPU context save area, like, the spot where the context is gonna be saved to. that's the destination, bestie 💖
• spu — pointer to the SPU iomem structure. yes, that one. 👑

---

🔥 DESCRIPTION 🔥

so the whole vibe is: grab the locks, do the save operation, then return. that's it. that's the function. 💀

it's giving "responsible older sibling" energy honestly — it does not just barrel in and start saving, it acquires the locks first, then performs the save operation, and then hands control back to you. considerate. iconic. 🫶

lowkey a reminder that this is kernel-land, so the locking isn't optional, it's the whole point of the function existing separately. slay. 💜

and that's the page! brought to you by ./arch/powerpc/platforms/cell/... — October 2026, Kernel API Manual edition. mwah, go forth and save those contexts responsibly 🌈💖
