STRUCT LEAPRAID_TOPO_NODE(9)

💅 struct leapraid_topo_node(9) 💅

okay bestie, listen up — this is the manual page for struct leapraid_topo_node(9) from the Kernel API Manual, and it's literally the SAS topology node for LeapRAID. think of it as the little index card that says "hi, this is a thing in the fabric, here's where it lives and who its parents are" 🦋

✨ NAME ✨

struct leapraid_topo_node — SAS topology node for LeapRAID

no cap, that's the whole vibe. one struct, one job: keep track of a node in the SAS topology.

---

🎀 SYNOPSIS 🎀

struct leapraid_topo_node {
    struct list_head list;
    struct list_head sas_port_list;
    struct leapraid_card_port *card_port;
    struct leapraid_card_phy *card_phy;
    struct sas_rphy *rphy;
    struct device *parent_dev;
    u64 sas_address;
    u64 sas_address_parent;
    u8 phys_num;
    u16 hdl;
    u16 enc_hdl;
    u64 enc_lid;
    u8 resp;
 };

look at her. fourteen fields. main character energy fr fr 💖

🌸 Members 🌸

okay so this is the part where we meet everyone in the group chat 👑

• list — the list head for linking nodes together. that's her job, that's her whole personality.
• sas_port_list — a list of SAS ports. yes, another list. she's a connector.
• card_port — the associated card port. like, which port on the card she's vibing with.
• card_phy — the associated card PHY.
• rphy — the SAS remote PHY device.
• parent_dev — pointer to the parent device. found family 💜
• sas_address — the SAS address of this node.
• sas_address_parent — the parent node's SAS address. iykyk.
• phys_num — number of physical links.
• hdl — the handle identifier.
• enc_hdl — the enclosure handle.
• enc_lid — the enclosure logical identifier.
• resp — the response status flag.

heads up bestie 🫶 — phys_num and resp are u8, hdl and enc_hdl are u16, and sas_address, sas_address_parent and enc_lid are u64. the widths are literally right there in the synopsis, don't come for me.

aaaand that's the page 🌈 it ships out of ./drivers/scsi/leapraid, dated October 2026, and the footer literally just says struct leapraid_topo_node(9) again because she's iconic like that. go read the other forty-two pages, i'll wait 💅✨🎀
