sci_port_co...lidate_ports(9)

🌸 NAME 🌸

sci_port_configuration_agent_validate_ports — okay so bestie, the manpage literally gives you no one-liner after that dash. Nothing. Empty. She's mysterious like that 💅 (the title's the whole vibe: it's the port-configuration-agent port validator, iykyk)

Oh and real quick — this whole thing lives in the Kernel API Manual, so jot that down 🎀

---

✨ SYNOPSIS ✨

enum sci_status sci_port_configuration_agent_validate_ports (struct
isci_host *ihost , struct sci_port_configuration_agent *port_agent );

Not me typing this out character for character, spaces included, because we do not fumble the signature 🙈

---

🫶 ARGUMENTS 🫶

• ihost — the controller object that contains the port agent. Like, the whole host, the main character 👑
• port_agent — the port configuration agent for the controller. This is the girl we're actually vibe-checking ✨

---

💖 DESCRIPTION 💖

So this routine will validate the port configuration is correct for the SCU hardware. That's the whole job. No cap. 🔥

And the SCU hardware allows for port configurations as follows:

• LP0 -> (PE0), (PE0, PE1), (PE0, PE1, PE2, PE3)
• LP1 -> (PE1)
• LP2 -> (PE2), (PE2, PE3)
• LP3 -> (PE3)

Like, LP0 is out here with options (she contains multitudes, honestly iconic), and LP1, LP2, LP3 are much more chill about it 🦋

Then there's the return situation, enum sci_status, and there's two moods:

• SCI_SUCCESS — the port configuration is valid for this port configuration agent. Slay! 🎉
• SCI_FAILURE_UNSUPPORTED_PORT_CONFIGURATION — the port configuration is not valid for this port configuration agent. Not slay 😭 But at least she tells you.

fr fr, run the check before you commit to a config — this function is literally the vibe check for your ports, and ignoring the failure return is giving chaos energy 💀

Alright bestie, that's the whole page 🍓 She ships from ./drivers/scsi/isci, dated October 2026, and she's filed under sci_port_co...lidate_ports(9) (yes the header truncates her name, it's giving quirky but we love her anyway) 💜✨
