dpu_rm_print_state(9)

✨ NAME ✨

dpu_rm_print_state — bestie, this one literally just outputs the RM private state 💅

fr fr, that's the whole gig. It's a little function from the Kernel API Manual (yes, the kernel has a manual, and yes it's iconic), and its entire main-character job is dumping out the private state of the RM. No cap.

---

🎀 SYNOPSIS 🎀

void dpu_rm_print_state (struct drm_printer *p , const struct
dpu_global_state *global_state );

okay so it returns void — nothing comes back, it's giving "the journey is the destination" 🦋 — and it takes exactly two things, both listed below. Not one, not three. Two. Periodt.

---

🌸 ARGUMENTS 🌸

• p — a DRM printer. that's it, that's the arg. it's your printer, it's a struct drm_printer *, it's where the output goes 🖨️✨
• global_state — the global state. the const struct dpu_global_state * one. the state, but global. iykyk 💜

ngl, these are both extremely self-explanatory and honestly? we love a low-drama signature. no surprises, no hidden gems, just a printer and a state. 🫶
