STRUCT MPI3MR_SAS_PHY(9)

💅 struct mpi3mr_sas_phy(9) 💅

okay bestie, this page is from the Kernel API Manual, and it’s all about struct mpi3mr_sas_phy(9) — the internal SAS Phy information page. think of it as the group chat for one little phy: who it’s related to, what it identifies, and which firmware handles it’s holding onto. 🔥

🎀 NAME 🎀

struct mpi3mr_sas_phy — internal SAS Phy information. that’s the whole assignment, no cap. 💖

✨ SYNOPSIS ✨

struct mpi3mr_sas_phy {
    struct list_head port_siblings;
    struct sas_identify identify;
    struct sas_identify remote_identify;
    struct sas_phy *phy;
    u8 phy_id;
    u16 handle;
    u16 attached_handle;
    u8 phy_belongs_to_port;
    struct mpi3mr_hba_port *hba_port;
};

🫶 Members 🫶

okay so the struct is giving “organized little bestie” energy, and these are the members:

• port_siblings — List of phys belonging to a port. basically the port’s phy squad. 🫶
• identify — Phy identification. the “who am I” of this phy. ✨
• remote_identify — Attached device identification. aka the “who’s on the other side” info. 🦋
• phy — SAS transport layer Phy object. the actual transport-layer object, not just vibes. 💅
• phy_id — Unique phy id within a port. one-of-one within its port, periodt. 👑
• handle — Firmware device handle for this phy. 💖
• attached_handle — Firmware device handle for attached device. 🎀
• phy_belongs_to_port — Flag to indicate phy belongs to port. yes, a whole flag for “i’m with the port.” 🌸

that’s the whole page, bestie. source/version is ./drivers/scsi/mpi3mr, date is October 2026, and the page is struct mpi3mr_sas_phy(9). stay iconic, and remember: kernel structs are just group chats with better type safety. 💖✨👑
