💅 mpt3sas_tran...add_host_phy(9)

okay so real talk — this is a page from the Kernel API Manual, and the star of the show is mpt3sas_transport_add_host_phy. she's a kernel function in the mpt3sas driver, and bestie, her whole job is telling the transport layer about a sas_host phy. like, "hey transport, meet phy 🫶". that's the vibe.

✨ NAME ✨

mpt3sas_transport_add_host_phy — report sas_host phy to transport 👑

literally what it says on the tin: this function reports a sas_host phy to the transport layer. no cap.

---

🌸 SYNOPSIS 🌸

int mpt3sas_transport_add_host_phy (struct MPT3SAS_ADAPTER *ioc , struct
_sas_phy *mpt3sas_phy , Mpi2SasPhyPage0_t phy_pg0 , struct device
*parent_dev );

so she takes four things and returns an int. that's it. that's the whole signature. copy it exactly, don't get creative with it 💀

---

🎀 ARGUMENTS 🎀

• ioc — the per adapter object. like, this is your adapter. main character energy for real 👑
• mpt3sas_phy — the mpt3sas per phy object. yes, one of these per phy. she's the phy's own little object 💖
• phy_pg0 — sas phy page 0. the page-0 data, bestie. Mpi2SasPhyPage0_t exactly, don't @ me.
• parent_dev — the parent device class object. every phy needs a parent, we love a family dynamic 🫶

---

⭐ RETURN ⭐

0 for success, non-zero for failure. that's the whole rule. zero = slay, non-zero = not slay 😭
