STRUCT KSZ_DESC(9)

📦 version 7.3.1, in nixpkgs unstable

✨ struct ksz_desc(9) ✨

okay so bestie, welcome to the Kernel API Manual — yes that's the whole manual name, we're being official today 💅 — and today's main character is struct ksz_desc, aka the descriptor structure. she's small, she's three fields, she's literally the entire vibe of a network descriptor. no cap.

🌸 NAME 🌸

struct ksz_desc — Descriptor structure 🎀

⭐ SYNOPSIS ⭐

struct ksz_desc {
    struct ksz_hw_desc *phw;
    struct ksz_sw_desc sw;
    struct ksz_dma_buf dma_buf;
 };

like... look at her. three members. immaculate. 🫶

💖 Members 💖

  • phw — a hardware descriptor pointer to uncached physical memory. yeah. uncached. she does not do the cache thing, she goes straight to the physical memory, that's her whole personality 🔥
  • sw — cached memory that holds the hardware descriptor values, so you can actually manipulate them. it's giving "the software-side stash of what the hardware thinks" ✨
  • dma_buf — an operating system dependent data structure that holds the info about the physical memory buffer allocation. os-dependent bestie, so behave accordingly 🦋

👑 SEE ALSO 👑

okay this list is long long, so buckle up, but every single one of these is part of the family and we are not skipping a single name, periodt 🙈

The Kernel file is ./drivers/net/ethernet/micrel/ksz884x.c — that's where the whole squad lives 💜

like I said. the whole squad. ate and left no crumbs 🌈

and that's the page bestie!! 💖 this one came out of ./drivers/net/ethernet/micrel and it's dated October 2026 — mwah, iconic, see u in the next (9) 🧚‍♀️✨
