STRUCT IPA_ENDPOINT_CONFIG(9)

💖 struct ipa_endpoint_config(9) 💖

okay so welcome to the Kernel API Manual, bestie — today's main character is struct ipa_endpoint_config, and honestly? she's giving hardware-configuration realness. No cap, this is the glow-up notes for an IPA endpoint. 🦋

---

✨ NAME ✨

struct ipa_endpoint_config — IPA endpoint hardware configuration. literally what it says on the tin, and she ate 💅

---

🌸 SYNOPSIS 🌸

struct ipa_endpoint_config {
    u32 resource_group;
    bool checksum;
    bool qmap;
    bool aggregation;
    bool status_enable;
    bool dma_mode;
    enum ipa_endpoint_name dma_endpoint;
    union {
      struct ipa_endpoint_tx tx;
      struct ipa_endpoint_rx rx;
    };
 };

like, that's the whole vibe. every field matters, don't skip a single one 🫶

🎀 Members 🎀

okay bestie, field-by-field tour, let's go:

• resource_group — a u32, aka the resource group you're assigning this endpoint to. it's giving "where do you belong" energy 🏠
• checksum — a bool saying whether checksum offload is enabled. yes/no, on/off, iconic behavior ⭐
• qmap — a bool for whether the endpoint uses the QMAP protocol. iykyk 📡
• aggregation — a bool for whether the endpoint supports aggregation. packing things together, we love to see it 🎁
• status_enable — a bool for whether the endpoint uses status elements. turn it on and she's got ✨status✨
• dma_mode — a bool for whether the endpoint operates in DMA mode. main character mode, honestly 🔥
• dma_endpoint — an enum ipa_endpoint_name: the peer endpoint, but only if you're operating in DMA mode. so like, a plus-one situation 🫶
• {unnamed_union} — anonymous. mysterious. no name, just vibes 🙈
• tx — a struct ipa_endpoint_tx: TX-specific endpoint information (see above). outgoing things, slay 💌
• rx — a struct ipa_endpoint_rx: RX-specific endpoint information (see above). incoming things, also slay 💌

ngl the tx and rx fields live inside that anonymous union together, so it's one or the other, not both at once. that's just how the struct is written, bestie 🧚
