💅 devl_port_resource_register(9) — the kernel API manual, bestie edition

okay so bestie, welcome to the Kernel API Manual page for devl_port_resource_register ✨ this one's short and sweet and honestly kind of iconic for how much it trusts you to read the other docs. let's get into it 🫶

---

🌸 NAME 🌸

devl_port_resource_register — devlink port resource register. that's it, that's the whole vibe. it registers a resource on a devlink port 💅

---

✨ SYNOPSIS ✨

int devl_port_resource_register (struct devlink_port *devlink_port ,
const char *resource_name , u64 resource_size , u64 resource_id , u64
parent_resource_id , const struct devlink_resource_size_params *params
);

like, six arguments, returns an int, classic. no cap 🌈

---

🎀 ARGUMENTS 🎀

• devlink_port — the devlink port. the main character, fr fr. the port you're doing this to 👑
• resource_name — the resource's name. yep, it's the name of the resource 🏷️
• resource_size — the resource's size. we love a u64 that says exactly what it is 💖
• resource_id — the resource's id. gotta have an id, iykyk 🔥
• parent_resource_id — the resource's parent id. yes it's a whole family tree situation 🌳
• params — the size parameters. it's a const struct devlink_resource_size_params *, so, you know, size params 🌸

---

🦋 DESCRIPTION 🦋

so here's the tea: generic resources should reuse the same names across drivers. not me stressing this enough: same names, across drivers, everywhere. consistency slays 💅

the generic resources list lives right here, and bestie you should go look at it:

Documentation/networking/devlink/devlink-resource.rst

it's basically the resource name canon. go read it, it's giving required reading 📚✨

---

💀 RETURN 💀

• 0 on success 🎉
• a negative error code otherwise 😭 (yes, negative. do not pass go, do not collect $200)
