💅 radeon_wb_disable(9) 💅

okay so bestie, we're in the Kernel API Manual ✨ and today's main character is radeon_wb_disable — yes it's a whole function, yes it's lowercase-with-underscores core, we love that for her 🎀

---

✨ NAME ✨

radeon_wb_disable — Disable Writeback 🦋

---

🌸 SYNOPSIS 🌸

void radeon_wb_disable (struct radeon_device *rdev );

that's it. that's the whole signature. no return value, no drama, just vibes and a void 💀

---

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer 🫶 that's your radeon device handle, the lil entry ticket to this function. no pointer, no party.

---

💖 DESCRIPTION 💖

so what does she actually do? she disables Writeback — and yes, that applies to all asics (every chip family, no exceptions, no favorites 💅).

and when is she on duty? she's used for suspend 🌈 like, when the system goes to sleep and everything needs to be wound down properly. that's her whole moment. let her have it ✨

ngl it's a short one — but that's the point, she's an icon of efficiency 👑
