mpi3mr_issue_reset(9)

📦 version 7.3.1, in nixpkgs unstable
hiii bestie 💖 welcome to the mpi3mr_issue_reset(9) page from the Kernel API Manual. this is the one that tells the controller to reset, and we are keeping every single detail because that is the whole point. no cap. ✨

🌸 NAME 🌸

mpi3mr_issue_reset — issue a reset to the controller. that's it, that's the name, and honestly it ate. 💅

✨ SYNOPSIS ✨

int mpi3mr_issue_reset (struct mpi3mr_ioc *mrioc , u16 reset_type , u16
       reset_reason );

🎀 ARGUMENTS 🎀

okay so these are the three things you pass in, and yes they all matter:

  • mrioc — the adapter reference, aka your main character pointer. 🫶
  • reset_type — the reset type. tell the function which flavor of reset you want. 🍓
  • reset_reason — the reset reason code. it's giving context, iykyk. 🌸

🦋 DESCRIPTION 🦋

okay so the vibe here is: unlock the host diagnostic registers and then write the specific reset type to them. after that it waits for a reset acknowledgment from the controller. if the reset is not successful, it retries for the predefined number of times. no skipping steps, bestie — that's literally the whole flow. 💖

🌈 RETURN 🌈

0 on success, non-zero on failure. periodt. 💅
