STRUCT DPU_HW_QOS_CFG(9)

✨ struct dpu_hw_qos_cfg(9) ✨

okay bestie, welcome to the struct dpu_hw_qos_cfg page from the Kernel API Manual (section 9, we're fancy like that) 💅 this one's all about pipe QoS configuration — yes, QoS as in quality of service, the thing your fave pipe cares about so much 🎀

---

🌸 SYNOPSIS 🌸

like, here's the whole vibe, literally character for character:

struct dpu_hw_qos_cfg {
    u32 danger_lut;
    u32 safe_lut;
    u64 creq_lut;
    bool danger_safe_en;
 };

no cap, that's the entire struct, and honestly? she's giving main character energy with only four members 💖

---

🦋 MEMBERS 🦋

okay so let's meet the squad, one by one:

• danger_lut — the LUT for generating the danger level based on fill level 🔥 like it looks at how full things are and decides "girl, this is danger territory"
• safe_lut — the LUT for generating the safe level based on fill level 🌈 same idea, but the chill outcome instead
• creq_lut — the LUT for generating the creq level based on fill level ⭐ (yes, u64 for this one — she's built different 👑)
• danger_safe_en — enables danger safe generation ✨ the little bool that says "yes, actually do the thing"

lowkey important: those LUTs are all about mapping fill level → level, iykyk 🧚

okay that's the whole page, bestie — every member, every LUT, nothing skipped, as it should be 💀

and for the cute sign-off: this one comes from ./drivers/gpu/drm/msm/disp/dpu1 (the source!), dated October 2026, and it's page struct dpu_hw_qos_cfg(9) of the Kernel API Manual — periodt 💅🌸
