hfi1_free_ctxtdata(9)

📦 version 7.3.1, in nixpkgs unstable

💖 hfi1_free_ctxtdata(9) — the kernel API manual, but make it make sense 💖

okay so bestie, we're in the Kernel API Manual and today's main character is hfi1_free_ctxtdata — literally the cleanup queen of the hfi1 driver. she frees a context's allocated data and then minds her own business. no cap. 🎀

✨ SYNOPSIS ✨

void hfi1_free_ctxtdata (struct hfi1_devdata *dd , struct hfi1_ctxtdata
*rcd );

like, that's the whole vibe. two args, zero return value, she does her thing and dips. 💅

🦋 ARGUMENTS 🦋

  • dd — the hfi1_ib device. the big boss device struct, the one that owns everything. 👑
  • rcd — the ctxtdata structure. the actual context data we're about to yeet into the void (respectfully). 🫶

🌸 DESCRIPTION 🌸

free up any allocated data for a context. that's it, that's the whole job. she's an icon, she's a legend, and the moment is hers.

but listen — it should never change any chip state, or global driver state. 🚨 like, for real for real. this is a purely local cleanup situation. she touches the context's allocated data and nothing else. no chip poking, no global driver meddling, none of that. it's giving "stay in your lane" and honestly? we love that for her. ⭐

bestie, take this seriously: any chip state or global driver state changes here would be a whole problem. this function is supposed to be side-effect-free outside its own little cleanup bubble. 💀
