💅 pru_rproc_set_ctable(9) — the Kernel API Manual page your bestie needs

✨ NAME ✨

pru_rproc_set_ctable — set the constant table index for the PRU 🌸

like, that's the job. that's the assignment. it ate and left no crumbs.

---

💖 SYNOPSIS 💖

int pru_rproc_set_ctable (struct rproc *rproc , enum pru_ctable_idx c ,
u32 addr );

look at that signature. iconic. returns an int, takes three args, no notes 💅

---

🎀 ARGUMENTS 🎀

• rproc — the rproc instance of the PRU. yep, the actual remoteproc thing you're working with, main character energy fr fr
• c — constant table index to set. it's an enum pru_ctable_idx, so it's giving "pick your index" ✨
• addr — physical address to set it to. a u32, so no funny business, just the physical address bestie

---

⭐ RETURN ⭐

0 on success, or errno in error case.

that's it. zero means slay, anything else means the errno is telling you what went wrong. no cap 💀

lowkey a reminder that this whole page lives under ./drivers/remoteproc — that's the home base 🏡

and that's the page!! mwah 💋 before you go, the little sign-off at the bottom: this one's from the ./drivers/remoteproc source, October 2026 era, and the page itself is pru_rproc_set_ctable(9) — periodt. 🌈🎀💜
