🎀 mpi3mr_post_transport_req(9) 🎀

okay so this is a page from the Kernel API Manual, bestie — we're talking kernel-level, no cap, and this lil function is the one that actually sends the thing 💅

✨ NAME ✨

mpi3mr_post_transport_req — literally just "issue transport requests and wait" 🫶

🌸 SYNOPSIS 🌸

int mpi3mr_post_transport_req (struct mpi3mr_ioc *mrioc , void *request
, u16 request_sz , void *reply , u16 reply_sz , int timeout , u16
*ioc_status );

like yes, that's a lot of arguments, but she's worth it, i promise 😭

🦋 ARGUMENTS 🦋

  • mrioc — your adapter instance reference, the main character of this whole operation 👑
  • request — a properly populated MPI3 request — and yeah, "properly" is doing heavy lifting there, don't play with her 🙈
  • request_sz — size of the MPI3 request, in case you were wondering how big the vibe is
  • reply — pointer to return MPI3 reply — this is where the firmware talks back 💌
  • reply_sz — size of the MPI3 reply buffer, keep it correct fr fr
  • timeout — timeout in seconds ⏰ like, actual seconds, not vibes
  • ioc_status — pointer to return ioc status — the lil receipt of how it went ⭐

💖 DESCRIPTION 💖

So this is a generic function for posting MPI3 requests from the SAS transport layer that uses the transport command infrastructure. Generic! Iconic! She does it all 💅

Here's the tea: this blocks for the completion of the request for timeout seconds. Yeah — blocks. Like it's sitting there waiting the whole time, patiently, like a bestie holding your bag 🫶

⚠️ and if the request times out? she faults the controller with the proper reason code. not a drill, that's real. no silent failures here, she's dramatic but she's honest 💀

On successful completion of the request, this function returns the appropriate ioc status from the firmware back to the caller — so the firmware's answer makes it all the way back to you, unbothered, slay ✨

🌈 RETURN 🌈

0 on success, non-zero on failure. that's it, that's the rule 🎀

the friend group, the whole group chat, every single one of them, i'm not leaving anyone out 💜

okay that's the whole page, you ate that, go forth and post your transport requests responsibly 🧚
