rproc_elf_sanity_check(9)

💅 NAME 💅

rproc_elf_sanity_check — the vibe check for your ELF32/ELF64 firmware image, bestie. Like, is this file even a real ELF or is it giving chaos? We find out.

This one lives in the Kernel API Manual, so you already know it's kernel-adjacent and slightly intimidating (but we're gonna make it make sense 🫶).

---

✨ SYNOPSIS ✨

int rproc_elf_sanity_check (struct rproc *rproc , const struct firmware
*fw );

Yes the spacing is a little feral, no we're not touching it, it's exactly how the kernel likes it. 💀

---

🌸 ARGUMENTS 🌸

• rproc — the remote processor handle. It's literally the lil' reference to the remote proc you're working with, your main character pointer. 👑
• fw — the ELF firmware image itself. The actual file we're about to judge. 🎀

---

🦋 DESCRIPTION 🦋

Okay so here's the whole deal: this function makes sure the firmware image is sane — as in, it's an actual correct ELF32/ELF64 file and not some cursed blob pretending to be one. ✨

That's it. That's the job. It's the bouncer at the club door checking your ID is a real ID before anything else gets to happen. 🙈

Ngl if your image is not a proper ELF32/ELF64 file, this is exactly where that gets caught. Consider it a kindness. 💖

🔥 RETURN 🔥

• 0 — slay, it passed. Success. ✅
• -EINVAL — upon any failure. Every single one. It's giving "no, and here's your generic error code" 😭

Like, go read the whole squad, they all hang out together in the loader. iykyk 🧚

Sign-off time: this lil' page is from ./drivers/remoteproc, dated October 2026 — the manual name was rproc_elf_sanity_check(9) all along, and honestly? Iconic. ✨💅🌸
