RHEL: Include request notifier
5d360b
5d360b
Introduce a new base VFIODevice strcut that will be used by both PCI
5d360b
and Platform VFIO device. Move VFIOPCIDevice fd field there. Obviously
5d360b
other fields from VFIOPCIDevice will be moved there but this patch
5d360b
file is introduced to ease the review.
5d360b
5d360b
Also vfio_mask_single_irqindex, vfio_unmask_single_irqindex,
5d360b
vfio_disable_irqindex now take a VFIODevice handle as argument.
