cb_alloc(9)

💅 cb_alloc — the kernel API manual, bestie edition 🎀

okay so real talk, this page lives in the Kernel API Manual, and it's all about cb_alloc(9) — the little function that gets your CardBus device a seat at the kernel table. let's get into it ✨

---

🌸 NAME 🌸

cb_alloc — add CardBus device

like, it literally adds a CardBus device. that's the whole vibe. 💅

---

✨ SYNOPSIS ✨

int __ref cb_alloc (struct pcmcia_socket *s );

that's it. one function, one argument, returns an int. iconic minimalism, no notes. 🫶

---

🦋 ARGUMENTS 🦋

• s — the pcmcia_socket where the CardBus device is located. that's your spot, that's where the device is at, that's the socket you're handing over. 📍

---

💖 DESCRIPTION 💖

okay so here's the tea: cb_alloc allocates the kernel data structures for a Cardbus device — yes, all the bookkeeping brain cells it needs to exist in kernel space 🧠✨ — and on top of that it handles the lowest level PCI device setup issues. low level. the basement level of PCI setup. it's giving main character energy in the plumbing department, ngl. 🔥

so when you call it, you're basically saying "bestie, set this CardBus device up from the ground floor" and it does exactly that. no cap. 💯

👑 SEE ALSO 👑

• the Kernel file ./drivers/pcmcia/cardbus.c — go read the source, iykyk 📖
• cb_free(9) — the other half of the story, the one that lets it go 🦋

---

a lil reminder: cb_alloc and cb_free(9) are a matched set. you allocate, you free. that's the circle of life, bestie. 🌈

mwah, that's the whole page — written by the ./drivers/pcmcia girlies, dated October 2026, filed under cb_alloc(9). go forth and slay your CardBus setup 💜🧚🌸
