mpt3sas_base_done(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

mpt3sas_base_done — base internal command completion routine

okay so real talk, bestie: this is straight out of the Kernel API Manual (section 9, function-page girlie 💅) and it's about one little callback that fires off when an internal command finishes its whole thing. it's giving "small function, big job" energy, and we're gonna read it together like the group chat. 🫶

🎀 SYNOPSIS 🎀

u8 mpt3sas_base_done (struct MPT3SAS_ADAPTER *ioc , u16 smid , u8
msix_index , u32 reply );

yeah she's a four-argument girlie and she returns a u8. no notes. ✨

🦋 ARGUMENTS 🦋

  • ioc — the per adapter object. it's your controller's whole lil identity in one struct, lowkey the main character of this whole file. 👑
  • smid — the system request message index. think of it as the lil ticket number that says which request we're talking about. 🎫
  • msix_index — the MSIX table index, supplied by the OS. the OS handed it over, so we didn't even have to guess. iconic of it. ✨
  • reply — the reply message frame (lower 32bit addr). literally the reply frame address, well, its lower 32 bits. that's the whole vibe. 📬

💖 RETURN 💖

she returns a u8, and the values are doing a very specific little dance:

  • 1 — meaning the mf should be freed from _base_interrupt
  • 0 — means the mf is freed from this function

so like… either big sibling _base_interrupt handles the mf cleanup, or this function already did it itself. no cap, that's the entire distinction and you do NOT wanna mix them up. 😭
