cache_debug_params(9) — Kernel API Manual energy 🫶

okay so this is the cache_debug_params(9) page, and it's basically the “save that for debug later” bestie of the kernel API world. Let’s get into it ✨

---

🌸 NAME 🌸

cache_debug_params — caches any params that needed to be maintained from the initial validation for debug purposes. It’s giving responsible little debug keeper, honestly 🎀

---

🌈 SYNOPSIS 🌈

void cache_debug_params (struct display_mode_lib *mode_lib );

---

🦋 ARGUMENTS 🦋

• mode_lib — the mode_lib input/output of the validate call. That’s the whole vibe for this one, bestie 💅

---

💜 DESCRIPTION 💜

So the DML getters can modify some of the VBA params that we are interested in — for example when calculating with dummy p-state latency. Because of that, this function caches any params here that we want for debugging. No cap, it’s just making sure the debug-relevant params are kept around 🫶

---

⭐ RETURN ⭐

void — literally no return value. Iconic, honestly 😌

---

🔥 SEE ALSO 🔥

• Kernel file ./drivers/gpu/drm/amd/display/dc/dml/display_mode_vba.c

byeee 💖 this page’s footer says source/version ./drivers/gpu/drm/amd/display/... and date October 2026 — and that’s the whole cache_debug_params(9) moment. Slay 🎀✨
