__fpga_region_register(9)

okay bestie, welcome to the __fpga_region_register(9) glow-up from the Kernel API Manual ✨ this one is literally about creating and registering an FPGA Region device 💖

🌸 NAME 🌸

__fpga_region_register — create and register an FPGA Region device 🎀

✨ SYNOPSIS ✨

bestie, here's the exact signature, no cap:

struct fpga_region * __fpga_region_register (struct device *parent ,
       struct fpga_manager *mgr , int (*get_bridges)(struct fpga_region *) ,
       struct module *owner );

🎀 ARGUMENTS 🎀

• parent — the device parent 👑
• mgr — the manager that programs this region 🔥
• get_bridges — optional function to get bridges to a list 🌉
• owner — module containing the get_bridges function 🫶

💅 DESCRIPTION 💅

okay so this simple version of the register function should be sufficient for most users — it's giving “default path, main character energy” ✨

the fpga_region_register_full function is available for users that need to pass additional, optional parameters 💖 that’s the whole vibe: simple version for most people, full version when you need the extra optional params 🎀

💖 RETURN 💖

you get back a struct fpga_region or an ERR_PTR 😭🫶 that’s it, that’s the return, periodt.
