STRUCT HBA_PORT(9)

💖 struct hba_port(9) 💖

okay so welcome to the Kernel API Manual, bestie — this is the page for struct hba_port(9), and we're gonna get you fluent in it, lowkey no cap. ✨

✨ NAME ✨

struct hba_port — saves each HBA's Wide/Narrow port info. literally its whole job, and it ate. 💅

🦋 SYNOPSIS 🦋

       struct hba_port {
           struct list_head list;
           u64 sas_address;
           u32 phy_mask;
           u8 port_id;
           u8 flags;
           u32 vphys_mask;
           struct list_head vphys_list;
        };

bestie, yes, list is in the struct too — the Members section below just doesn't give it a separate little blurb. iykyk. 🫶

🎀 Members 🎀

• sas_address — sas address of this wide/narrow port's attached device. iconic field, does exactly what it says. 🌸
• phy_mask — HBA PHY's belonging to this port. yes, "PHY's" — we're keeping the page's exact vibe. 😭
• port_id — port number. short, sweet, main character energy. 👑
• flags — hba port flags. that's the whole note, and honestly? periodt. 💀
• vphys_mask — mask of vSES devices Phy number. no cap, that's the exact description, and we're not changing it. 🦋
• vphys_list — list containing vSES device structures. the list bestie. the container. obsessed. 💜
