Linux IRQ and active should be okay. As to the vfio_device handle, you should link it from the vfio_platform_device instead. And for the vfio_platform_device, you can link it from the vfio_platform_irq instead. Once you've done this, embed the irq_bypass_producer struct in the vfio_platform_irq struct; in the new kvm_arch_* functions, go back to the vfio_platform_irq struct via container_of. From there you can retrieve pointers to the vfio_platform_device and the vfio_device. > - new fields on consumer side: the kvm handle, the gsi You do not need to add these. Instead, add the kvm handle to irqfd only. Like above, embed the irq_bypass_consumer struct in the irqfd struct; in the new kvm_arch_* functions, go back to the vfio_platform_irq struct via container_of.
