dpu_encoder...et_qos_remap(9)

💅 dpu_encoder...et_qos_remap(9) — from the Kernel API Manual, bestie ✨

Okay so real talk, this page lives in the Kernel API Manual and it's about dpu_encoder_phys_wb_set_qos_remap — yes that's a mouthful, and yes it's iconic 🎀. It's a tiny lil function in the DRM/MSM DPU writeback world, and we're gonna get you comfy with it in like two minutes flat.

✨ NAME ✨

dpu_encoder_phys_wb_set_qos_remap — sets the QoS remapper for writeback 🦋

That's the whole vibe. QoS remapping, but for writeback. Periodt.

---

🌸 SYNOPSIS 🌸

void dpu_encoder_phys_wb_set_qos_remap (struct dpu_encoder_phys
*phys_enc );

Notice the return type? It's void — this one does its thing and dips, no return value, no drama 💅.

---

🎀 ARGUMENTS 🎀

• phys_enc — pointer to the physical encoder. That's it, that's the whole argument list. Hand it your struct dpu_encoder_phys * and you're golden 🫶

Ngl this is one of the shortest pages ever — one function, one argument, zero return value. Lowkey a little slay of a manpage 🌟

Okay bye bestie, mwah 💜 This little gem shipped out of ./drivers/gpu/drm/msm/disp/dpu1 back in October 2026 — go forth and remap those QoSes ✨👑🎀
