ibmvscsi_handle_event(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

🌸 ibmvscsi_handle_event 🌸

okay so bestie, this is a page out of the Kernel API Manual β€” yes, the actual kernel, like the big one β€” and today's main character is ibmvscsi_handle_event. buckle up, it's gonna be a quick one but lowkey important πŸ’…

✨ NAME ✨

ibmvscsi_handle_event β€” the interrupt handler for crq events πŸŽ€

that's it. that's the job. she handles crq events when the interrupt hits and honestly? she ate.

πŸ’– SYNOPSIS πŸ’–

irqreturn_t ibmvscsi_handle_event (int irq , void *dev_instance );

look at her go. two args, one return type, zero drama. ✨

πŸ¦‹ ARGUMENTS πŸ¦‹

  • irq β€” the number of the irq to handle. and no, she does not use it πŸ™ˆ it's literally just there vibing in the parameter list. not every argument has a purpose bestie, some of them are just decorative (not really, don't tell the kernel devs I said that)
  • dev_instance β€” this one's the real deal: it's the ibmvscsi_host_data of the host that received the interrupt πŸ”₯ so like, the actual host data. the one who got the interrupt. she's holding it. it's giving responsible.

πŸ‘‘ DESCRIPTION πŸ‘‘

so what does she actually do? two things, and she does them with main character energy:

  • disables interrupts πŸ’€ (yes, really, that's her whole personality)
  • schedules srp_task 🌈

and then, always, every single time, no exceptions, she always returns IRQ_HANDLED. not sometimes. not "depends on the vibe". always. periodt. πŸ‘‘

no cap β€” the return value is never in question here. IRQ_HANDLED, every time, fr fr.

oh and before I go β€” the source lives at ./drivers/scsi/ibmvscsi, the date on this one is October 2026, and it's ibmvscsi_handle_event(9) all the way down. mwah πŸ’‹βœ¨ go handle those crq events, you're gonna slay. πŸŽ€
