MALI_C55_PARAMS_MAX_SIZE(9)

🌸 MALI_C55_PARAMS_MAX_SIZE(9) 🌸

ok so bestie, you're reading the Kernel API Manual page for MALI_C55_PARAMS_MAX_SIZE — and yeah, the name is giving "shouty macro," because that's literally what it is 💅

---

✨ NAME ✨

MALI_C55_PARAMS_MAX_SIZE — the absolute biggest possible size of all the Mali C55 Parameters, fr fr 👑

---

🦋 SYNOPSIS 🦋

MALI_C55_PARAMS_MAX_SIZE

---

💖 DESCRIPTION 💖

So here's the vibe: the parameters for the Mali-C55 are passed in as optional blocks. Cute, right? Very modular, very "choose your own adventure" 🎀

But — and this is the important part, bestie, don't miss it — the driver still needs to know the absolute maximum size. Why? Because it has to allocate a buffer sized appropriately to accommodate userspace tryna set every single possible parameter in a single frame. Like, all of them. At once. Main character energy 😭🔥

And about the list being a little repetitive — some structs show up in it multiple times. That's not a typo, ngl. It just reflects the fact that the same struct can be used with multiple different header types from :c:type:mali_c55_param_block_type. So if you were like "wait, didn't I just see that one"… yes. Yes you did. It's iconic like that 🫶

💀 quick reminder that this is a maximum size we're talking about — the driver is sizing a buffer for the worst-case "user asked for everything" scenario. Respect the hustle. 🍓

k that's the whole page bestie, ily, go read the header file 💜 — this one came from ./include/uapi/linux/media/arm, dated October 2026, and the page itself is MALI_C55_PARAMS_MAX_SIZE(9). slay, bye 🧚⭐
