panthor_gpu_flush_caches(9)

💅 panthor_gpu_flush_caches — like, the cache-flushing one ✨

Okay bestie, so this is a page straight out of the Kernel API Manual (yes, that manual), and it's all about panthor_gpu_flush_caches. Sounds intense? It's literally just "Flush caches." That's the whole NAME. Short, sweet, iconic. 🎀

---

✨ SYNOPSIS ✨

int panthor_gpu_flush_caches (struct panthor_device *ptdev , u32 l2 ,
       u32 lsc , u32 other );

That's the whole call, no cap. Returns an int, takes four things. Let's get into them 👇

---

🌸 ARGUMENTS 🌸

• ptdev — your device. Device. The main character, honestly.
• l2 — the L2 flush type. L2 flush type. Yeah, it's a u32 and it tells the L2 what kind of flush we're doing 💫
• lsc — the LSC flush type. LSC flush type. Same deal, LSC edition.
• other — the "everything else" flush type. Other flush type. Cute lil catch-all, we love her 🫶

---

⭐ RETURN ⭐

0 on success, and a negative error code otherwise. That's it, that's the whole vibe check — zero means slay, anything negative means something went sideways 😭

🧚 Lowkey important: the synopsis, the argument types, and the return values are exactly as written up there. Copy them character for character and don't get creative — that's the one thing we don't improvise on 💀

Anyway, that's the page!! This one came from ./drivers/gpu/drm/panthor and it's dated October 2026, so like… mark your calendars bestie 🗓️✨ Mwah, love u, go flush those caches 💜
