RPPX1_PARAMS_MAX_SIZE(9)

💅 RPPX1_PARAMS_MAX_SIZE(9) — a little kernel-api moment

okay so bestie, welcome to the RPPX1_PARAMS_MAX_SIZE page 💖 it lives in the Kernel API Manual, and honestly? it's a short one. short but iconic. let's get into it 🎀

---

✨ NAME ✨

RPPX1_PARAMS_MAX_SIZE — literally just: the maximum size of all the RPP-X1 parameter blocks 👑 no cap, that's the whole gig.

---

🌸 SYNOPSIS 🌸

RPPX1_PARAMS_MAX_SIZE

that's it. that's the whole synopsis. she's a macro, she doesn't need a whole cast list 🫶

---

🦋 DESCRIPTION 🦋

okay so the one thing you actually gotta know here 👇

some types get reported twice, because the same block might be instantiated in multiple pipes. yep. multiple pipes. same block. two reports. it's giving "why is this here twice" but it's also, like, correct 💅

so like, don't panic when you see the same type show up more than once — that's not a bug, that's just how it is when a block lives in more than one pipe 🧚 no notes.
