DPU_DEBUG(9)

💖 DPU_DEBUG(9) 💖

okay so this is a page from the Kernel API Manual — yes bestie, the kernel has lore too — and it's all about DPU_DEBUG, the macro that handles your kms/plane/crtc/encoder/connector logs. it's giving "logging but make it DRM-coded" ✨

---

🌸 NAME 🌸

DPU_DEBUG — the macro for kms/plane/crtc/encoder/connector logs 🫶

like, that's literally its whole job. one macro, five whole categories of display pipeline things to log about. she's versatile. she's employed. we love her 💅

---

⭐ SYNOPSIS ⭐

DPU_DEBUG (fmt , ... );

that's it. that's the whole vibe check. fmt, then your little trail of ... besties trailing behind it 🎀

---

🦋 ARGUMENTS 🦋

• fmt — a pointer to the format string 👑 like, the blueprint of the message, the main character of the call, the outline before the glow-up
• ... — variable arguments 🌈 the supporting cast! however many you need, they just keep coming, no cap

no cap: fmt is a pointer to a format string, and ... is variable arguments. don't come for me, that's exactly what the page says 💀

• DPU_DEBUG_DRIVER(9) — her sibling, also iconic
• ktime_compare_safe(9) — time comparison, but safe, and honestly? slay

and that's the whole page!! short and sweet, just like a good group chat message 🍓
