✨ mpi_ssp_completion ✨

okay so real talk, this is a page from the Kernel API Manual and it's honestly a little iconic 💅 we're talking about mpi_ssp_completion(9) — the function that handles the moment firmware slides into your mentions to say "hey bestie, that SSP request? done ✅"

🎀 NAME 🎀

mpi_ssp_completion — the one that processes the event that FW response to the SSP request 💫 (yes we're keeping the original phrasing vibes, it's giving kernel-speak and we respect it)

🦋 SYNOPSIS 🦋

void mpi_ssp_completion (struct pm8001_hba_info *pm8001_ha , void *piomb );

like, that's the whole signature. short king 👑

🌸 ARGUMENTS 🌸

  • pm8001_ha — our hba card information 🫶 this is our card, the main character
  • piomb — the message contents of this outbound message 📨 literally the whole lil payload

💖 DESCRIPTION 💖

okay so picture this: FW has completed a ssp request — for example a IO request — and after it has filled the SG data with the data, it will trigger this event representing that he has finished the job 🎉 no cap, the job is done done.

so yeah, at that point: please check the corresponding buffer 👀 (this is not optional bestie, that's the homework).

and then we will tell the caller — who maybe waiting the result — to tell upper layer that the task has been finished 💅 periodt. the waiting caller gets their lil answer, the upper layer gets the news, everybody eats.
