STRUCT QCOM_ICC_NODE(9)

✨ struct qcom_icc_node(9) ✨

okay bestie, so this page is from the Kernel API Manual and it's literally all about struct qcom_icc_node — the Qualcomm-specific interconnect node situation 💅 like, this is the struct that holds your node's whole personality: its name, its links, its bandwidth math, and its QoS glow-up data.

🦋 SYNOPSIS 🦋

struct qcom_icc_node {
    const char *name;
    struct icc_node *node;
    u16 num_links;
    u16 channels;
    u16 buswidth;
    u64 sum_avg[QCOM_ICC_NUM_BUCKETS];
    u64 max_peak[QCOM_ICC_NUM_BUCKETS];
    struct qcom_icc_bcm *bcms[MAX_BCM_PER_NODE];
    size_t num_bcms;
    const struct qcom_icc_qosbox *qosbox;
    struct qcom_icc_node *link_nodes[];
};

no cap, it's giving "flexible array member main character energy" with that link_nodes[] at the end 🔥

🌸 Members 🌸

• name — the node name, aka what shows up in debugfs — it's the node's whole identity for debugging purposes 🫶
• node — the icc_node that goes with this node. they're literally a package deal 💖
• num_links — the total number of links. all of them. counted. periodt ✨
• channels — how many channels this node has 💅
• buswidth — the width of the interconnect between a node and the bus — very "how wide is the vibes pipeline" of it 🎀
• sum_avg — the current sum aggregate value of all avg bw requests 🧮
• max_peak — the current max aggregate value of all peak bw requests — highkey the ceiling of the whole situation ⭐
• bcms — the list of bcms associated with this logical node 👑
• num_bcms — number of bcms, it's giving "count your bcms before you count your blessings" 🙈
• qosbox — the QoS config data associated with the node, aka the quality-of-service lore 🌈
• link_nodes — the links associated with this node 🦋

go read them, iykyk 💜

ngl this struct lives in ./drivers/interconnect/qcom — that's the neighborhood, bestie 🏡

okay that's the whole page, mwah 💋 this one came from the Kernel API Manual, dated October 2026, filed under ./drivers/interconnect/qcom — and if you made it this far you're literally an interconnect icon, fr fr 🌟🫶
