efi_parse_options(9)

💖 NAME 💖

okay so welcome to efi_parse_options(9) from the Kernel API Manual, bestie! This is the page for efi_parse_options — Parse EFI command line options ✨. We're parsing EFI command line options and honestly? It's giving main character energy 💅.

✨ SYNOPSIS ✨

efi_status_t efi_parse_options (char const *cmdline );

🎀 ARGUMENTS 🎀

• cmdline — the kernel command line, periodt. That's the string we're handing over 🫶.

🦋 DESCRIPTION 🦋

This function parses the ASCII string cmdline for EFI options, which are denoted by the efi= option, e.g. efi=nochunk. Lowkey simple, highkey important ✨.

heads up, bestie: efi= is parsed in two very different environments — first in the early boot environment of the EFI boot stub, and subsequently during the kernel boot. The way that one option lives two lives? Obsessed 😭💖.

No cap, that's the whole description. Keep both environments in mind and you're slaying 🌸.

🌈 RETURN 🌈

• status code — it returns a status code, bestie. That's it. That's the return 💅✨.
