💅 univ8250_console_match(9) 💅

okay so welcome to this little Kernel API Manual page, bestie — we're talking about univ8250_console_match, and it's giving non-standard console matching energy fr fr ✨

---

🌸 NAME 🌸

univ8250_console_match — non-standard console matching, no cap 💖

---

🎀 SYNOPSIS 🎀

int univ8250_console_match (struct console *co , char *name , int idx ,
       char *options );

---

🦋 ARGUMENTS 🦋

• co — the registering console, periodt 🫶
• name — name from console command line, yep that one 💅
• idx — index from console command line, iconic little number ⭐
• options — ptr to option string from console command line, iykyk 🌈

---

✨ DESCRIPTION ✨

so this function only attempts to match console command lines of the form:

console=uart[8250],io|mmio|mmio16|mmio32,<addr>[,<options>]
console=uart[8250],0x<addr>[,<options>]

This form is used to register an initial earlycon boot console and replace it with the serial8250_console at 8250 driver init. like, that's the whole plot 💀

It performs console setup for a match (as required by interface). If no <options> are specified, then assume the h/w is already setup. lowkey important 🧚

Returns 0 if console matches; otherwise non-zero to use default matching. that's the vibe check right there 👑
