💅 match_devname_and_update_preferred_console 💅

okay bestie, so this is a page from the Kernel API Manual (section 9, kernel developer land 🧚) and it's literally about match_devname_and_update_preferred_console — yes that's the whole name, it's giving "my parents gave me a very descriptive name" energy and honestly? iconic. Anyway, she updates a preferred console when a matching devname shows up. Let's get into it 💖

✨ NAME ✨

match_devname_and_update_preferred_console — update a preferred console when a matching devname is found 🎀

🌸 SYNOPSIS 🌸

int match_devname_and_update_preferred_console (const char *devname ,
       const char *name , const short idx );

🦋 ARGUMENTS 🦋

  • devname — a DEVNAME:0.0 style device name, like literally the whole vibe of the device's name ✨
  • name — the name of the corresponding console driver, e.g. "ttyS" 👑
  • idx — the console index, e.g. port number, the little number that tells you which one 🍓

💜 DESCRIPTION 💜

So what she does: the function checks whether a device with the given devname is preferred via the console=DEVNAME:0.0 command line option. 👀

Then — and this is the good part — she fills in the missing console driver name and console index, so that a later register_console call could find (match) and enable this device. Like she's setting up the group chat so everyone can find each other fr fr 🫶

Where you'd actually use her: when a driver subsystem initializes particular devices with already known DEVNAME:0.0 style names. And plot twist, she could also predict which console driver name and index this device would later get associated with. psychic? no, just good at her job 💅

⭐ RETURN ⭐

0 on success, negative error code on failure. slay when it's 0, sad girl hours when it's negative 😭

🌈 SEE ALSO 🌈

She runs with a whole squad, no cap. Kernel file ./kernel/printk/printk.c plus:

ngl that's a long list but every single one of them is invited to the function's birthday party 🎂 you're welcome.

okay that's the whole page bestie, you ate that 💅✨ this little gem comes from ./kernel/printk, dated October 2026, and yeah — section 9, kernel API, exactly where you'd expect to find her. bye pookie, go enable some consoles 💖🎀🦋
