get_port_ssp_rate(9)

✨ get_port_ssp_rate — the manual page bestie 💅

okay so real talk, this is get_port_ssp_rate from the Kernel API Manual, and honestly? she's a little lookup function with main character energy 👑

---

🎀 NAME 🎀

get_port_ssp_rate — match the extended port status to the SSP rate, no cap 🌸

---

🦋 SYNOPSIS 🦋

enum usb_ssp_rate get_port_ssp_rate (struct usb_device *hdev , u32
ext_portstatus );

like literally that's the whole signature, copy it exactly pls, i'm not about to let you typo it 🙈

---

💖 ARGUMENTS 💖

• hdev — the hub device 🫶 like, the actual hub we're talking about here
• ext_portstatus — the extended port status ✨ yes that whole u32 of it

---

🔥 DESCRIPTION 🔥

so basically the vibe check here is: take that extended port status speed id and match it up against the SuperSpeed Plus sublink speed capability attributes 💫

then, based on the number of connected lanes and the speed, she returns the corresponding enum usb_ssp_rate — that's it, that's the whole job, and she ate 👑

ngl the original even says "Base on" instead of "Based on" and i love that for her, icon energy, we keep the lore 🧚
