📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

mpi3mr_repost_diag_bufs — the girl whose whole job is reposting host diag buffers 💅

ok bestie, welcome to the Kernel API Manual ✨ this one is short and sweet, no cap.

✨ SYNOPSIS ✨

int mpi3mr_repost_diag_bufs (struct mpi3mr_ioc *mrioc );

that's it. that's the whole signature. one argument, one int coming back at you 🫶

🌸 ARGUMENTS 🌸

  • mrioc — your adapter instance reference 🦋 like, the actual card you're talking about. that's your girl. you hand her over and the function knows exactly which adapter it's doing repost business for.

🦋 DESCRIPTION 🦋

okay so here's the vibe: this function reposts firmware and trace diag buffers based on the global trigger flag from driver page 2 ✨

that's the entire lore. firmware diag buffers + trace diag buffers get reposted, and the thing that decides whether that happens is the global trigger flag living in driver page 2. the way it just... checks the flag and does the repost 😌 iconic behaviour, honestly.

ngl this description in the original is like two lines long, so please don't come for me — I'm not adding lore that isn't there 🙈 everything above is literally all the manpage tells us.

⭐ RETURN ⭐

  • 0 on success 🎉 slay, buffers reposted, everybody go home
  • non-zero on failures 😭 so like, always check it, bestie. don't just assume. a non-zero return is your cue to pay attention.

also yes, mpimr_initialize_reply_sbuf_queues(9) really is spelled like that in the original and I am NOT fixing it 😭 copy-paste gremlins are forever, don't @ me 💀

and that's the whole page, bestie 🌈 this little gem comes to you from ./drivers/scsi/mpi3mr, dated October 2026, and it's page mpi3mr_repost_diag_bufs(9) of the Kernel API Manual — okay bye, go repost those buffers, ily 🫶✨
