: Optional name to associate with group, visible in sysfs | |
iommu_group_alloc - Allocate a new group This function is called by an iommu driver to allocate a new iommu group. The iommu group represents the minimum granularity of the iommu. Upon successful return, the caller holds a reference to the supplied group in order to hold the group until devices are added. Use iommu_group_put() to release this extra reference count, allowing the group to be automatically reclaimed once it has no devices or external references. | |

bus_set_iommu - set iommu-callbacks for the bus : bus. : the callbacks provided by the iommu-driver
This function is called by an iommu driver to set the iommu methods used for a particular bus. Drivers for devices on that bus can use the iommu-api after these ops are registered. This special function is needed because IOMMUs are usually devices on the bus itself, so the iommu drivers are not initialized when the bus is set up. With this function the iommu-driver can set the iommu-ops afterwards.

iommu_group_register_notifier - Register a notifier for group changes : the group to watch : notifier block to signal
This function allows iommu group users to track changes in a group. See include/linux/iommu.h for actions sent via this notifier. Caller should hold a reference to the group throughout notifier registration.

iommu_group_set_iommudata - set iommu_data for a group : the group : new data : release function for iommu_data
iommu drivers can store data in the group for use when doing iommu operations. This function provides a way to set the data after the group has been allocated. Caller should hold a group reference.

iommu_set_fault_handler() - set a fault handler for an iommu domain : iommu domain : fault handler : user data, will be passed back to the fault handler
This function should be used by IOMMU users which want to be notified whenever an IOMMU fault happens.
The fault handler itself should return 0 on success, and an appropriate error code otherwise.
