STRUCT _SAS_PORT(9)

💫 struct _sas_port — the whole vibe, explained 💫

okay so bestie, welcome to the <italic>Kernel API Manual</italic> entry for struct _sas_port(9) 🎀 — yes the manual name is literally just the struct name, we love a self-titled icon. this page is wide/narrow sas port information and it's giving "backstage pass to the expander" energy. let's get into it ✨

🌸 NAME 🌸

struct _sas_port — wide/narrow sas port information, fr fr. that's the whole subtitle and honestly? it ate. 💅

---

🦋 SYNOPSIS 🦋

here's the struct in all its glory, copied EXACTLY, no cap, do not touch a single character:

struct _sas_port {
    struct list_head port_list;
    u8 num_phys;
    struct sas_identify remote_identify;
    struct sas_rphy *rphy;
    struct sas_port *port;
    struct hba_port *hba_port;
    struct list_head phy_list;
 };

look at her. seven fields. main character energy. 🌟

👑 Members 👑

every single one, bestie, no skipping — this is the whole cast list 🫶

• port_list — list of ports belonging to expander. like the group chat member list, but for ports. 📋
• num_phys — number of phys belonging to this port. a u8, so it's cute and small and knows its limits. 🔢
• remote_identify — attached device identification. who's that Pokémon? it's the device on the other end, and this is its ID card. 🪪
• rphy — sas transport rphy object. pointer to a struct sas_rphy, living its best transport life. 🚀
• port — sas transport wide/narrow port object. pointer to a struct sas_port, the actual port object, extremely iconic of it. 🎀
• hba_port — hba port entry containing port's port number info. yes "port" three times, i don't make the rules, the kernel does. 💀
• phy_list — _sas_phy list objects belonging to this port. those underscores are load-bearing, keep them exactly like that. 🙈
