mpi3mr_post_cfg_req(9)

🎀 NAME 🎀

mpi3mr_post_cfg_req — issue config requests and wait, bestie 💅

Welcome to the Kernel API Manual, this is the page for mpi3mr_post_cfg_req(9), and yes we're gonna get through the whole thing together 🫶

---

✨ SYNOPSIS ✨

int mpi3mr_post_cfg_req (struct mpi3mr_ioc *mrioc , struct
mpi3_config_request *cfg_req , int timeout , u16 *ioc_status );

okay so that's the whole signature, literally copy it exactly, don't be weird about the spacing, it's fine 🌸

---

🦋 ARGUMENTS 🦋

• mrioc — the adapter instance reference, aka your controller's whole personality 🎀
• cfg_req — the configuration request itself, the actual thing you're posting
• timeout — timeout, in seconds ⏰ (yes seconds, not jiffies, not vibes)
• ioc_status — a pointer used to return the ioc status back atcha 💖

---

💜 DESCRIPTION 💜

So this is the generic function for posting an MPI3 configuration request to the firmware. Nothing spicy, it's the standard little courier 🧚

It blocks for the completion of the request for timeout seconds. Like, it will sit there and wait. Patient queen energy 👑

⚠️ and if the request times out, this function faults the controller with the proper reason code. Not a drill, not a cute little retry — it faults the controller. iykyk 💀

On successful completion of the request, this function returns the appropriate ioc status from the firmware back to the caller. The firmware says a thing, you get told the thing 🔥

---

⭐ RETURN ⭐

• 0 on success 🎉
• non-zero on failure 😭

That's it. Zero is the good one, periodt.
