mv88e6352_g2...t_has_serdes(9)

✨ mv88e6352_g2_scratch_port_has_serdes — NAME ✨

okay so this is a page from the Kernel API Manual (yes, the mv88e6352_g2...t_has_serdes(9) one, we love a truncated title bestie 💅🫶) and it's literally about one little function:

mv88e6352_g2_scratch_port_has_serdes — tells you whether a port has a serdes or not 💖

---

🦋 SYNOPSIS 🦋

int mv88e6352_g2_scratch_port_has_serdes (struct mv88e6xxx_chip *chip ,
int port );

that's it, that's the whole vibe check 🌸

---

🎀 ARGUMENTS 🎀

• chip — the chip private data. it's giving "main character struct" ngl 👑
• port — the port number we're checking for serdes 🍓

---

💜 DESCRIPTION 💜

so basically this function indicates whether the port may have a serdes attached, according to the pin strapping — and that strapping? it's cached at reset (that's scratch config3, iykyk ✨).

Here's the tea on what it returns ☕:

• returns 0 if the port is not configured to have a serdes 💀
• returns 1 if the port is configured to have a serdes attached 🔥

no cap, that's the whole story. lowkey iconic for how tiny it is.
