dpmac_get_counter(9)

📦 version 7.3.1, in nixpkgs unstable

💖 dpmac_get_counter(9) — a.k.a. the dpmac_get_counter page, bestie 💖

okay so this is a kernel API manual page (dpmac_get_counter(9)) and honestly? it's a little snack. it does exactly one thing and it does it cute. let's get into it 🎀

✨ NAME ✨

dpmac_get_counter — read a specific DPMAC counter 💅

like, one (1) counter. the specific one you asked for. no cap.

🌸 SYNOPSIS 🌸

int dpmac_get_counter (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , enum dpmac_counter_id id , u64 *value );

that's the whole vibe. it returns an int, it takes five args, and it is not here to waste your time 🦋

🫶 ARGUMENTS 🫶

okay bestie, here's who's who in the group chat:

  • mc_io — pointer to an opaque I/O object. opaque meaning you do not get to peek inside, it's giving mysterious main character energy 🙈
  • cmd_flags — command flags; one or more of 'MC_CMD_FLAG_'. yes, plural, you can stack 'em 💅
  • token — the token of the DPMAC object. it's the little ID badge that says which DPMAC we're talking to 👑
  • id — the requested counter ID. it's an enum dpmac_counter_id, so like, pick your fighter ⭐
  • value — returned counter value. this is where the answer lands, it's an out-param bestie, that's the whole point 🎀

🔥 RETURN 🔥

it hands back the requested counter, and '0' otherwise. that's it, that's the whole return arc 😭

ngl if you're reading this page you're probably already deep in the DPMAC lore. proud of you. drink some water 🍓

and that's the page, bestie!! it shipped from ./drivers/net/ethernet/freesca... and it is dated October 2026 (yes, the future, iconic behaviour ⏳✨). mwah, go read your counters 💜
