dpu_encoder_..._wb_setup_fb(9)

💅 dpu_encoder_phys_wb_setup_fb — Kernel API Manual ✨

okay so bestie, welcome to the <pink>Kernel API Manual</pink> 🎀 and today's main character is dpu_encoder_phys_wb_setup_fb(9) — yes the header up top says dpu_encoder_..._wb_setup_fb(9) but that's just the title being extra dramatic and abbreviating, the real full name is down below, iykyk 💖

✨ NAME ✨

dpu_encoder_phys_wb_setup_fb — setup output framebuffer 🖼️ fr fr that's literally the whole vibe

---

🌸 SYNOPSIS 🌸

void dpu_encoder_phys_wb_setup_fb (struct dpu_encoder_phys *phys_enc ,
                                   const struct msm_format *format );

like, it returns void, so it's giving "I do the work and I don't owe you a status code" energy 😌✨

---

🦋 ARGUMENTS 🦋

• phys_enc — Pointer to physical encoder 👑 that's the struct dpu_encoder_phys * bestie, the physical encoder in question
• format — Format of the framebuffer 🎨 this one's const struct msm_format *, so it's the format of the framebuffer, held constant, no touching, we respect it

💀 no cap, the whole point is just: hand it your phys_enc and your format and it sets up the output framebuffer. That's the plot. That's the episode. Slay.
