STRUCT IPA_ENDPOINT(9)

🌸 NAME 🌸

okay so <rainbow>struct ipa_endpoint</rainbow> — it's literally the whole vibe of an IPA endpoint, packaged as one struct 💖 (and yes bestie, this is from the Kernel API Manual, section 9, we're in the big leagues now).

✨ SYNOPSIS ✨

here's the whole thing, no cap, exactly as it lives:

struct ipa_endpoint {
    struct ipa *ipa;
    enum gsi_ee_id ee_id;
    u32 channel_id;
    u32 endpoint_id;
    bool toward_ipa;
    struct ipa_endpoint_config config;
    u32 skb_frag_max;
    u32 evt_ring_id;
    struct net_device *netdev;
    unsigned long replenish_flags[BITS_TO_LONGS( IPA_REPLENISH_COUNT)];
    u64 replenish_count;
    struct delayed_work replenish_work;
 };

she's giving structured. she's giving organized. we stan 🎀

💖 Members 💖

• ipa — the IPA pointer, aka the main character this endpoint belongs to 👑
• ee_id — the execution environment the endpoint is associated with 🧚
• channel_id — the GSI channel this endpoint uses 🦋
• endpoint_id — the IPA endpoint number, its little ID badge 🎫
• toward_ipa — the endpoint direction: true = TX, false = RX (so it's a whole bool situation, keep up 💅)
• config — the default endpoint configuration, the fit she wears normally ✨
• skb_frag_max — the maximum allowed number of TX SKB fragments, the fragment budget fr fr 🌸
• evt_ring_id — the GSI event ring used by the endpoint, the ring to her name 💍
• netdev — a network device pointer — but only if the endpoint uses one, so like, conditional 🫶
• replenish_flags — replenishing state flags, the receipts of what's going on 🔥
• replenish_count — total number of replenish transactions committed, a running tally ngl 💜
• replenish_work — the work item used for repeated replenish failures, which like… 😭 when one replenish doesn't slay, she tries again
