bootconfig_c...ne_requested(9)

💅 bootconfig_cmdline_requested

okay so bestie, welcome to the Kernel API Manual ✨ — this one's about bootconfig_cmdline_requested, and no cap, it's lowkey the vibe-checker for whether "bootconfig" got passed on the cmdline. let's get into it 🎀

---

🌸 NAME 🌸

bootconfig_cmdline_requested — literally answers the question: was "bootconfig" passed on the cmdline? 🕵️‍♀️

---

✨ SYNOPSIS ✨

bool bootconfig_cmdline_requested (const char *boot_cmdline , int
       *end_offset );

---

🫶 ARGUMENTS 🫶

• boot_cmdline — the kernel command line you wanna inspect. bestie, it does not get modified, she's untouched, we're respectful here 💖
• end_offset — if it's non-NULL, we set it to the offset of the init arguments that follow a "--" separator, or 0 when there's none. giving "pointer to the tea" energy fr fr

---

👑 DESCRIPTION 👑

so here's the deal 🌈 — this parses a private copy of boot_cmdline (because parse_args is destructive, like, it will absolutely wreck the original, no survivors 😭) and then reports whether "bootconfig" is present before the "--" separator.

setup_arch uses this to gate prepending the build-time embedded cmdline ⭐ and setup_boot_config uses it for the runtime opt-in and to locate the init arguments via end_offset. the whole point of sharing one parser is so the early and late paths stay agreeing on what counts as opt-in — no mixed signals, no drama, main character consistency only 👑

one tiny caveat bestie: CONFIG_BOOT_CONFIG_FORCE is not folded in here 🫣 — callers apply it where they need it. so don't come for this function, she's just doing her job.

💀 heads up: parse_args is destructive — that's literally why this function parses a private copy. don't hand it the real cmdline and expect it back in one piece.
