__platform_create_bundle(9)

💫 __platform_create_bundle — Kernel API Manual ✨

okay bestie, so this page is literally called __platform_create_bundle(9) and it lives in the Kernel API Manual, and it's about the one-two punch of registering a driver and spinning up the device it goes with. no cap, it's a bundled deal 🎀

🌸 NAME 🌸

__platform_create_bundle — register driver and create corresponding device

like, both things. at once. the driver registration and the device creation, together, in one call 💅

🦋 SYNOPSIS 🦋

struct platform_device * __platform_create_bundle (struct platform_driver *driver , int (*probe)(struct platform_device *) , struct resource *res , unsigned int n_res , const void *data , size_t size , struct module *module , const char *mod_name );

that's a lot of parameters, i know 😭 but stay with me, we're gonna go through every single one:

✨ ARGUMENTS ✨

• driver — the platform driver structure 💖 this is the driver that's gonna get registered.
• probe — the driver probe routine, probably from an __init section. yes, "probably" — that's the actual wording, don't @ me.
• res — the set of resources that needs to be allocated for the device 🧚
• n_res — number of resources. you know, the count of the thing above.
• data — platform specific data for this platform device 🍓
• size — size of platform specific data. yep, pairs with data. iconic duo.
• module — module which will be the owner of the driver 👑
• mod_name — module name string ⭐

🔥 DESCRIPTION 🔥

So here's the vibe check: use this in legacy-style modules that probe hardware directly and register a single platform device and corresponding platform driver. that's the whole use case, iykyk 🫶

Returns struct platform_device pointer on success, or ERR_PTR on error. so like, always check it — if it's an error pointer you gotta handle it, bestie, don't just vibe past it 🙈
