In doing so, create the symbol IOMMUFD_DRIVER which designates the builtin code that will be used by drivers when selected. Today this means MLX5_VFIO_PCI and PDS_VFIO_PCI. IOMMU drivers will do the same (in future patches) when supporting dirty tracking and select IOMMUFD_DRIVER accordingly. Given that the symbol maybe be disabled, add header definitions in iova_bitmap.h for when IOMMUFD_DRIVER=n Signed-off-by: Joao Martins <joao.m.martins@xxxxxxxxxx> --- drivers/iommu/iommufd/Kconfig | 4 +++ drivers/iommu/iommufd/Makefile | 1 + drivers/{vfio => iommu/iommufd}/iova_bitmap.c | 0 drivers/vfio/Makefile | 3 +-- drivers/vfio/pci/mlx5/Kconfig | 1 + drivers/vfio/pci/pds/Kconfig | 1 + include/linux/iova_bitmap.h | 26 +++++++++++++++++++ 7 files changed, 34 insertions(+), 2 deletions(-) rename drivers/{vfio => iommu/iommufd}/iova_bitmap.c (100%)
