STRUCT CDNSP_ERST_ENTRY(9)

🦋 struct cdnsp_erst_entry(9) 🦋

okay so bestie, welcome to the kernel API manual for struct cdnsp_erst_entry — literally the even ring segment table entry object. yes that's the whole vibe. it's a tiny struct and she ate 💅

---

💖 NAME 💖

struct cdnsp_erst_entry — the even ring segment table entry object. that's it, that's her whole identity, no cap ✨

---

🌸 SYNOPSIS 🌸

here's the shape of her, exactly as she is, don't touch a single character:

struct cdnsp_erst_entry {
    __le64 seg_addr;
    __le32 seg_size;
    __le32 rsvd;
 };

look at that alignment, she's so organized 🎀

🫶 MEMBERS 🫶

• seg_addr — a 64-bit event ring segment address. that's the address, 64 whole bits of it, living her best life 💖
• seg_size — the number of TRBs in the segment. that's how many TRBs are in the segment, bestie, it's giving "count" energy 🔥
• rsvd — she's in the struct too! the original page doesn't describe her at all, so like… we're not gonna make anything up, she just exists 🙈
