sci_controll..._invalid_phy(9)

🌸 sci_controll..._invalid_phy(9) 🌸

okay bestie, welcome to the Kernel API Manual, section 9 — this one's called sci_controll..._invalid_phy(9) and it's a whole macro moment. it's short, it's sweet, and it does exactly one thing but does it iconically 💅

---

✨ NAME ✨

sci_controller_clear_invalid_phy — that's literally the whole name, no tagline, no subtitle, nothing. it's giving mysterious main character energy 🎀

---

✨ SYNOPSIS ✨

sci_controller_clear_invalid_phy (controller , phy );

that's it. that's the whole vibe. two args, one macro, zero complications fr fr 💖

---

✨ ARGUMENTS ✨

okay so this is the part where the documentation just... did not show up 😭 and i'm not gonna make stuff up, because that would be a lie and we don't do that here:

• controller — -- undescribed -- 🫠 like, the docs literally say undescribed. no notes. no explanation. just vibes.
• phy — -- undescribed -- 🫠 same situation bestie, the manpage is out here giving us nothing on this one too.

so yeah, that's the full scoop on the args: the source page lists both of them as undescribed, and i'm passing that along exactly as-is because i'm not about to invent lore 🌸

---

✨ DESCRIPTION ✨

so here's what this macro actually does, and ngl it's lowkey satisfying: it clears the bit in the invalid phy mask for this controller object 🔥

that's the whole job. one bit, one mask, one controller object. clean, surgical, ate 💅

and what's it for? it's used to control messages reported for invalid link up notifications ✨ so like, when a link up notification comes in that's invalid, this is the little knob that helps manage what messages get reported about it. it's the behind-the-scenes girlie keeping the messaging situation under control, periodt 👑

fr fr though — the page gives us exactly that much and no more. no edge cases listed, no return values, no warnings. just the bit-clearing and the notification-message-controlling. don't go reading extra behaviour into it, bestie 🙈

---

✨ SEE ALSO ✨

go touch some other docs, queen, they're all hanging out here:

• ./drivers/scsi/isci/host.h — the header file where this whole situation lives
• struct sci_power_control(9)
• enum sci_controller_states(9)

🦋 a lil sign-off 🦋

this page came to you from ./drivers/scsi/isci, dated October 2026, and yes the title up top and the footer down bottom both say sci_controll..._invalid_phy(9) because the truncation is part of the aesthetic apparently 😭💜

now go clear that invalid phy bit, bestie — you got this 🌈⭐
