[Qemu-devel] [PATCH v8 04/19] hw/vfio/pci: introduce minimalist VFIODevice with fd |
|
Date: |
Sun, 30 Nov 2014 18:35:09 +0000 |
Introduce a new base VFIODevice strcut that will be used by both PCI
and Platform VFIO device. Move VFIOPCIDevice fd field there. Obviously
other fields from VFIOPCIDevice will be moved there but this patch
file is introduced to ease the review.
Also vfio_mask_single_irqindex, vfio_unmask_single_irqindex,
vfio_disable_irqindex now take a VFIODevice handle as argument.
