[PATCH v1 0/5] vfio: Make emulated devices prepared for vfio device cdev

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The .bind_iommufd op of vfio emulated devices are either empty or does
nothing. This is different with the vfio physical devices, to add vfio
device cdev, need to make them act the same.

This series first makes the .bind_iommufd op of vfio emulated devices
to create iommufd_access, this introduces a new iommufd API. Then let
the driver that does not provide .bind_iommufd op to use the vfio emulated
iommufd op set.

Thanks,

  iommufd: Create access in vfio_iommufd_emulated_bind()

  vfio-iommufd: No need to record iommufd_ctx in vfio_device
  vfio-iommufd: Make vfio_iommufd_emulated_bind() return iommufd_access
    ID
  Samples/mdev: Uses the vfio emulated iommufd ops set in the mdev
    sample drivers
  vfio: Check the presence for iommufd callbacks in
    __vfio_register_dev()
