ibmvscsi_handle_event(9)
πΈ ibmvscsi_handle_event πΈ
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 π
β¨ NAME β¨
ibmvscsi_handle_event β the interrupt handler for crq events π
that's it. that's the job. she handles crq events when the interrupt hits and honestly? she ate.
π SYNOPSIS π
irqreturn_t ibmvscsi_handle_event (int irq , void *dev_instance );
look at her go. two args, one return type, zero drama. β¨
π¦ ARGUMENTS π¦
irqβ the number of the irq to handle. and no, she does not use it π 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_instanceβ this one's the real deal: it's theibmvscsi_host_dataof the host that received the interrupt π₯ so like, the actual host data. the one who got the interrupt. she's holding it. it's giving responsible.
π DESCRIPTION π
so what does she actually do? two things, and she does them with main character energy:
- disables interrupts π (yes, really, that's her whole personality)
- schedules
srp_taskπ
and then, always, every single time, no exceptions, she always returns IRQ_HANDLED. not sometimes. not "depends on the vibe". always. periodt. π
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 πβ¨ go handle those crq events, you're gonna slay. π
