dpaa2_io_service_rearm(9)

📦 version 7.3.1, in nixpkgs unstable

✨ dpaa2_io_service_rearm ✨

Okay bestie, welcome to the dpaa2_io_service_rearm(9) page — it's a kernel API manual, it lives in section 9, and it's literally the glow-up your DPIO notification needed. 🦋

🎀 SYNOPSIS 🎀

int dpaa2_io_service_rearm (struct dpaa2_io *d , struct
       dpaa2_io_notification_ctx *ctx );

That's the whole vibe check: it takes two args and hands you back an int. No cap. 💅

🌸 ARGUMENTS 🌸

  • d — the given DPIO service. Like, the one. Your main character service. 👑
  • ctx — the notification context. This is the little info packet that knows whose notification we're rearming. 🎀

💖 DESCRIPTION 💖

Okay so, storytime. 📖 Once a FQDAN/CDAN has been produced, the corresponding FQ/channel is considered "disarmed". Ie. the user can issue pull dequeue operations on that traffic source for as long as it likes. It's giving "no thoughts, just dequeue." 🌈

Eventually it may wish to "rearm" that source to allow it to produce another FQDAN/CDAN — and that's exactly what this function achieves. Obsessed. It's literally the "bestie, come back, I miss you" of kernel notifications. 🫶

Returns 0 for success. That's it. That's the whole return. Slay. ✨

Ngl, the 0-means-success thing is the entire contract here — no fancy error catalogues on this page, so don't go inventing any. 🙈

🔥 SEE ALSO 🔥

The source of truth is the kernel file ./drivers/soc/fsl/dpio/dpio-service.c — go read it, iykyk. 👀

And here's the whole friend group, all of them, in order, no one left out, periodt:

Source spot: ./drivers/soc/fsl/dpio — dated October 2026. 🗓️ That's the tea, bestie, go forth and rearm responsibly 💜🧚‍♀️⭐
