irdma_stat_val(9)

📦 version 7.3.1, in nixpkgs unstable

👑 NAME 👑

irdma_stat_val — bestie, this is the one that extracts the HW counter value from a statistics buffer. That's it, that's the whole job, and it does it gorgeously ✨

This little icon lives in the Kernel API Manual section of the manual pages — page irdma_stat_val(9), in case you were wondering which one of the 400 irdma pages you opened 🫶

✨ SYNOPSIS ✨

u64 irdma_stat_val (const u64 *stats_val , u16 byteoff , u8 bitoff , u64 bitmask );

Like, look at that signature. Four arguments, returns a u64. It's giving "small function, big responsibility" and honestly? No notes 💅

🎀 ARGUMENTS 🎀

Okay so here's the group chat roster of parameters, and yes you need all of them:

  • stats_val — a pointer to the statistics buffer. This is the main character, the place where all the counter data actually lives 🌸
  • byteoff — the byte offset of the counter value in the buffer, which needs to be 8B-aligned (u16, so it behaves). Don't be messy about this one 🎯
  • bitoff — the bit offset of the counter value within that 8B entry (u8). So like… byteoff finds you the entry, bitoff finds you the actual bits inside it. Teamwork, lowkey iconic 💖
  • bitmask — the maximum counter value (u64), for example 0xffffff for a 24-bit counter. This is the ceiling, the limit, the "know your worth" of the whole operation 👑

Return type is u64, so the value comes back to you as a nice big unsigned integer, hydrated and ready 🧚

First, the source file, so you can go read the real thing:

  • ./drivers/infiniband/hw/irdma/ctrl.c

And now… the list. The legendary list. The way this page cross-references basically the ENTIRE irdma driver — it's giving "everyone is here" 🤯 Enjoy, bestie:

Okay that's the whole page, bestie — no gatekeeping, every single cross-reference preserved 💜

And a cute lil sign-off for the credits, because we always cite our sources 🫶: this page comes from the source tree at ./drivers/infiniband/hw/irdma, dated October 2026, and it's page irdma_stat_val(9) — go forth and read your hardware counters with main character energy. Periodt 💅🎀
