[PATCH v9 Kernel 2/5] vfio iommu: Add ioctl defination to get dirty pages bitmap.

2019-11-12 Thread Kirti Wankhede
All pages pinned by vendor driver through vfio_pin_pages API should be considered as dirty during migration. IOMMU container maintains a list of all such pinned pages. Added an ioctl defination to get bitmap of such pinned pages for requested IO virtual address range. Signed-off-by: Kirti Wankhede
