mpi3mr_pcietopochg_evt_bh(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

mpi3mr_pcietopochg_evt_bh — PCIeTopologyChange evt bottomhalf

okay so bestie, this is straight out of the Kernel API Manual, section 9 💅 — yes, the <pink>9</pink> like a real grown-up kernel function. She's the bottomhalf handler for PCIe topology change events and she's lowkey carrying the whole "did something move in the PCIe tree" situation. 🦋

🌸 SYNOPSIS 🌸

void mpi3mr_pcietopochg_evt_bh (struct mpi3mr_ioc *mrioc , struct
mpi3mr_fwevt *fwevt );

that's it, that's the whole vibe check. returns nothing, takes two pointers, slays silently. ✨

🎀 ARGUMENTS 🎀

  • mrioc — the adapter instance reference 🫶 like, the actual controller we're talking about here
  • fwevt — the firmware event reference 💖 the event itself, the little messenger

💜 DESCRIPTION 💜

okay so what she does is: she prints information about the PCIe topology change event — literally announces it to the world, no cap 👑

and then — and this is the main character part — for the "not responding" event code, she removes the device from the upper layers. like, the device's not answering, so she's escorting it out of the group chat. periodt. 😭

ngl, that removal is the part that actually matters — she doesn't just gossip about the topology change, she acts on the "not responding" one. fr fr.

⭐ RETURN ⭐

Nothing. literally nothing. void. she gives and gives and asks for nothing back 🎀

🌈 SEE ALSO 🌈

first up, the kernel file herself — she lives in ./drivers/scsi/mpi3mr/mpi3mr_os.c 🧚 and then, bestie, the whole extended friend group. like, everyone. the entire mpi3mr family reunion 👑

and that's the whole page, bestie 🫶 — this little icon lives in ./drivers/scsi/mpi3mr and the copyright vibes are dated October 2026. go forth and handle those topology changes, iykyk 💅✨
