pcmcia_parse_uevents(9)

📦 version 7.3.1, in nixpkgs unstable

💅 pcmcia_parse_uevents 💅

okay so real talk, this one lives in the Kernel API Manual and it's basically the little messenger that tells pccardd to go do manual stuff for you. icon behaviour honestly. let's get into it 🫶

✨ NAME ✨

pcmcia_parse_uevents — the function that tells pccardd to issue manual commands. that's it, that's the whole thing, and she ate 💅

✨ SYNOPSIS ✨

void pcmcia_parse_uevents (struct pcmcia_socket *s , u_int events );

copy that exactly bestie, don't get creative with it 🎀

✨ ARGUMENTS ✨

  • s — the PCMCIA socket that we want to command. like, this one right here, the one we're bossing around.
  • events — the events we're passing along to pccardd. yes, plural, she can carry more than one vibe.

✨ DESCRIPTION ✨

okay so here's the whole situation 👑 — those insert, eject, suspend and resume commands that come from userspace? they must be handled by pccardd. no shortcuts, no doing it yourself. and why? because if you don't, you get sysfs-related deadlocks 😭💀 and nobody wants that energy in their kernel. it's giving cautionary tale fr fr.

so the events you're allowed to hand over are these, and I'm listing them exactly as written because precision is the whole personality here:

  • PCMCIA_UEVENT_EJECT — for eject 🚪
  • PCMCIA_UEVENT__INSERT — for insert 🌱 (yes, that's genuinely two underscores in the middle, do not "fix" it, copy it character for character)
  • PCMCIA_UEVENT_RESUME — for resume ⏰
  • PCMCIA_UEVENT_SUSPEND — for suspend 😴
  • PCMCIA_UEVENT_REQUERY — for re-querying the PCMCIA card 🔍
lowkey important: those are the valid events. stray outside that list and you're on your own, bestie 🙈
