okay so welcome to the Kernel API Manual, bestie — this page is literally all about vfio_ap_irq_disable(9), and it's giving “disable the interrupt, clear the interrupt, handle the resources” energy. 💅✨

✨ NAME ✨

vfio_ap_irq_disable — disables and clears an ap_queue interrupt. periodt. 🎀

🦋 SYNOPSIS 🦋

struct ap_queue_status vfio_ap_irq_disable (struct vfio_ap_queue *q );

🎀 ARGUMENTS 🎀

• q — the vfio_ap_queue. that's the whole argument, she's simple and iconic. 🦋

💖 DESCRIPTION 💖

okay so the function uses ap_aqic to disable the interruption, and in case of success, reset in progress or IRQ disable command already proceeded, it does the little two-step: it calls vfio_ap_wait_for_irqclear to check for the IRQ bit to be clear, and it calls vfio_ap_free_aqic_resources to free the resources associated with the AP interrupt handling. slay. ✨

in the case the AP is busy, or a reset is in progress, it retries after 20ms, up to 5 times. no cap, she's persistent. 💀

it returns if ap_aqic function failed with invalid, deconfigured or checkstopped AP. like, that's the bail-out vibe. 🫶

🌈 RETURN 🌈

returns a struct ap_queue_status. that's it, that's the return. 💚
