Different IOMMU hardware would have different hardware information. So the information reported differs as well. To let the external user understand the difference. enum iommu_hw_info_type is defined. For the iommu
s/difference. enum/difference, enum/
- @hw_info: IOMMU hardware information. The type of the returned data
is
marked by the output type of this op. Type is one of
enum iommu_hw_info_type defined ininclude/uapi/linux/iommufd.h.
The drivers that support this op should define a unique type
in include/uapi/linux/iommufd.h. The data buffer returned by this
op is allocated in the IOMMU driver and the caller should free it
after use. Return the data buffer if success, or ERR_PTR on
failure.simplified as:
