mpi3mr_add_host_phy(9)

✨ mpi3mr_add_host_phy ✨

okay so bestie, welcome to the Kernel API Manual 💅 today we're looking at mpi3mr_add_host_phy(9) — and yes, it does exactly one thing and it does it fabulously. 🦋

---

🌸 NAME 🌸

mpi3mr_add_host_phy — report sas_host phy to SAS transport 💫

like, that's the whole job. it takes a phy and introduces it to the SAS transport layer. networking era. 👑

---

🎀 SYNOPSIS 🎀

int mpi3mr_add_host_phy (struct mpi3mr_ioc *mrioc , struct
mpi3mr_sas_phy *mr_sas_phy , struct mpi3_sas_phy_page0 phy_pg0 , struct
device *parent_dev );

it's giving four arguments and a dream ✨

---

🦋 ARGUMENTS 🦋

• mrioc — ur adapter instance reference, the main character of the whole driver ngl 🌈
• mr_sas_phy — the internal Phy object, lowkey the internals, handle with care 🫶
• phy_pg0 — SAS phy page 0, iconic data structure, no notes 💜
• parent_dev — the prent device class object 💀 (that's how the page spells it, "prent", i'm just the messenger, don't come for me)

---

⭐ RETURN ⭐

• 0 — success, we ate, periodt 🔥
• non-zero — failure, and we do NOT love that for us 😭

🎀 friendly reminder bestie: this page lives in ./drivers/scsi/mpi3mr and it's dated October 2026 — so go check it out, and remember, the phy is not gonna report itself 💅🫶

that's the page, ily, bye! 🍓🧚💜
