STRUCT DPAA2_FL_ENTRY(9)

💅 NAME ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — today's main character is struct dpaa2_fl_entry, and it is literally the structure for a frame list entry. that's it, that's the vibe. no cap. 🦋

🌸 SYNOPSIS 🌸

struct dpaa2_fl_entry {
    __le64 addr;
    __le32 len;
    __le16 bpid;
    __le16 format_offset;
    __le32 frc;
    __le32 ctrl;
    __le64 flc;
 };

look at her. seven fields, all little-endian, all iconic. 👑 (yes the closing brace has a lil extra space, she's just like that, we don't fix her 💅)

🧚 MEMBERS 🧚

okay so every single one of these fields has a job and honestly? they all ate. 🔥

• addr — address in the FLE. that's the spot. 💖
• len — length in the FLE. how much stuff we're talking about.
• bpid — buffer pool ID. which pool she's living in 🫶
• format_offset — format, offset, and short-length fields, all bundled up together like a little trio of besties. ngl that's a lot in one field but she's handling it. ✨
• frc — frame context. the lore. the backstory. 🦋
• ctrl — control bits... including pta, pvt1, pvt2, err, etc — and yes, the "etc" is doing heavy lifting here, iykyk 💀
• flc — flow context address. where the flow context lives. 🌈
