sci_port_add_phy(9)

💅 sci_port_add_phy(9) — like, the Kernel API Manual, bestie

okay so welcome to the sci_port_add_phy(9) page, part of the Kernel API Manual ✨ this is the little corner of the kernel that lives in ./drivers/scsi/isci and it's literally here to explain how you glue a PHY onto a port. no drama, just vibes and structs 🫶

---

✨ NAME ✨

sci_port_add_phy — the function name, iconic, no notes. (the original page left this one blank so we're just gonna let it breathe 🎀)

---

🌸 SYNOPSIS 🌸

enum sci_status sci_port_add_phy (struct isci_port *iport , struct
       isci_phy *iphy );

that's the whole signature, copy it exactly, don't @ me 💅

---

🦋 ARGUMENTS 🦋

• iport — this one is the port, aka where the phy is gonna live. it specifies the port in which the phy will be added, fr fr.
• iphy — this is the phy itself, the little guy that's about to get added to the port. this parameter is the phy which is to be added to the port 🧚

---

👑 DESCRIPTION 👑

ok so real talk: this method will add a PHY to the selected port. that's the whole job. she's focused 💖

and the way it tells you how it went? it returns an enum sci_status. so:

• SCI_SUCCESS — slay!! the phy has been added to the port 🎉
• any other status — not slay 😭 that's a failure to add the phy to the port. no partial credit, no consolation prize, just failure.

heads up bestie: the original page is super clear that only SCI_SUCCESS means it worked. anything else = the add did not happen. check your status, always 🌈
