💅 mpt3sas_scsi...ent_callback(9)

okay so bestie, real talk: this is a page out of the Kernel API Manual, and the header up there is truncated to mpt3sas_scsi...ent_callback(9) because somebody's terminal said "no ma'am, too long" — the actual function is mpt3sas_scsih_event_callback, and that's what we're talking about. buckle up 🎀

✨ NAME ✨

mpt3sas_scsih_event_callback — the firmware event handler, and not to be dramatic but it gets called at ISR time. 😭🔥

🌸 SYNOPSIS 🌸

u8 mpt3sas_scsih_event_callback (struct MPT3SAS_ADAPTER *ioc , u8
msix_index , u32 reply );

🦋 ARGUMENTS 🦋

  • ioc — the per adapter object, aka the whole vibe of this one controller 💜
  • msix_index — the MSIX table index, literally handed to you by the OS 👑
  • reply — the reply message frame, and yes bestie it's the lower 32bit addr 🍓

⚡ CONTEXT ⚡

interrupt. that's it. that's the context. you are in interrupt context, act accordingly 🙈

💫 DESCRIPTION 💫

so what does it actually do? lowkey barely anything, and that's the whole point, no cap. this function merely adds a new work task into ioc->firmware_event_thread. that's it. no heavy lifting, no main character energy, just yeet a task into the thread and dip 💅

the actual tasks get worked from _firmware_event_work, and that happens in user context, where it's safe to do the real stuff. iconic division of labour fr fr 🫶

🎀 RETURN 🎀

two possible moods:

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

pick the right one bestie, the memory is watching 👀

🔥 SEE ALSO 🔥

this list is long long. like, scrolling-for-days long. but every single one of these belongs here so let's go, Kernel file ./drivers/scsi/mpt3sas/mpt3sas_scsih.c and friends:

and that's the whole page, bestie 🫶 that massive list came to you from ./drivers/scsi/mpt3sas and it's dated October 2026. go read the source, it's literally all in mpt3sas_scsih.c — mwah 💋✨
