STRUCT MPI3MR_SAS_PORT(9)

💅 struct mpi3mr_sas_port — Internal SAS port information 🎀

okay bestie, this is struct mpi3mr_sas_port, from the Kernel API Manual. it lives in ./drivers/scsi/mpi3mr/mpi3mr.h and it's literally the internal glow-up of SAS port info. no cap. it's giving "backstage pass to the HBA" energy and we are obsessed 💖

✨ SYNOPSIS ✨

struct mpi3mr_sas_port {
    struct list_head port_list;
    u8 num_phys;
    u8 marked_responding;
    int lowest_phy;
    u64 phy_mask;
    struct mpi3mr_hba_port *hba_port;
    struct sas_identify remote_identify;
    struct sas_rphy *rphy;
    struct sas_port *port;
    struct list_head phy_list;
};

like, she's structured. she's typed. she's iconic. copy her exactly, okay? don't be weird about it 🫶

🦋 MEMBERS 🦋

• port_list — the list of ports belonging to a SAS node. it's the group chat of ports fr fr 💬
• num_phys — how many phys are associated with this port. the phy headcount ✨
• marked_responding — used while refreshing the sas ports. yes, the original says "refresing" — we're keeping it, it's canon 💀
• lowest_phy — the lowest phy ID of the current sas port. only valid for the controller port, so don't go using it elsewhere 🙈
• phy_mask — the phy_mask of the current sas port. also only valid for the controller port, same vibe check as above 💅
• hba_port — HBA port entry. the plug-in to the whole HBA situation 🔌
• remote_identify — the attached device identification. who's that diva on the other end? 👑
• rphy — the SAS transport layer rphy object. main character of the transport layer ⭐
• port — the SAS transport layer port object. adjacent main character, equally iconic 🌈
• phy_list — the mpi3mr_sas_phy objects belonging to this port. all her little phy besties 🧚
