sci_port_is_phy_mask_valid(9)

💅 NAME 💅

sci_port_is_phy_mask_valid — okay so bestie, the NAME line literally ends in a dash and then nothing. No description, no little tagline, just sci_port_is_phy_mask_valid - and then silence. Iconic of it honestly. We're in the <pink>Kernel API Manual</pink>, section 9, and this is the girl who tells you whether a PHY mask is valid for a port. That's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

bool sci_port_is_phy_mask_valid (struct isci_port *iport , u32 phy_mask
);

She takes two things and hands you back a bool. Lowkey the simplest little signature ever. 🫶

---

🌸 ARGUMENTS 🌸

• iport — the port object 🚪 — this is the port you're asking about, like "hey can this specific port handle the mask". It's a struct isci_port *.
• phy_mask — the PHY mask that belongs to this port 🎭 — the thing you're getting the validity check on, a u32.

---

💖 DESCRIPTION 💖

So this method returns a true value if the port's phy mask can actually be supported by the <purple>SCU</purple>. That's it, that's the job. ✨

Here's the list of valid PHY mask configurations for each port — memorize it, flashcard it, put it on your wall, no cap 📝:

• Port 0 — [[3 2] 1] 0
• Port 1 — [1]
• Port 2 — [[3] 2]
• Port 3 — [3]

(yes, Port 0 really does have two spaces in there. Copy it exactly. Don't be cute with it 🙈)

Heads up: those bracket nestings are literal — keep them character for character or the whole vibe check fails.

This method returns a boolean indication specifying if the phy mask can be supported 💁‍♀️:

• true — this is a valid phy assignment for the port ✅ slay
• false — this is not a valid phy assignment for the port ❌ not slay
