C3_ISP_PARAMS_MAX_SIZE(9)

💅 C3_ISP_PARAMS_MAX_SIZE 💅

okay bestie, so this is a page from the Kernel API Manual, section 9 — like, kernel-internals territory. the whole vibe here is C3_ISP_PARAMS_MAX_SIZE. buckle up, it's a short one but it's important ✨

---

🌸 NAME 🌸

C3_ISP_PARAMS_MAX_SIZE — the Maximum size of all C3 ISP Parameters 🎀 no cap, that's literally the whole name. it's the ceiling. the limit. the "how big can this get" of it all.

---

🦋 SYNOPSIS 🦋

C3_ISP_PARAMS_MAX_SIZE

that's it. that's the whole thing. a macro living its best main-character life 💅

---

✨ DESCRIPTION ✨

okay so picture this: the parameters for the C3 ISP get passed in as optional blocks — very choose-your-own-adventure, very flexible, we love that for them 🫶

BUT. the driver still needs to know the absolute maximum size, because bestie… it has to allocate a buffer. and that buffer has to be big enough for the worst-case scenario: userspace deciding to set all possible parameters in a single frame 😭 like every single one. all at once. in one frame. feral behavior honestly, but the driver is not about to get caught lacking.

so that's the whole deal — this is the number that says "if someone went absolutely unhinged and set every param, this is how much room you need". allocate accordingly or perish 💀
