1053  * iommu_register_device_fault_handler() - Register a device fault handler

1055  * @handler: the fault handler

1058  * When an IOMMU fault event is received, this handler gets called with the

1059  * fault event and data as argument. The handler should return 0 on success. If

1060  * the fault is recoverable (IOMMU_FAULT_PAGE_REQ), the consumer should also

1061  * complete the fault by calling iommu_page_response() with one of the following

1064  * - IOMMU_PAGE_RESP_INVALID: terminate the fault

1065  * - IOMMU_PAGE_RESP_FAILURE: terminate the fault and stop reporting

1068  * Return 0 if the fault handler was installed successfully, or an error.

1080     /* Only allow one fault handler registered for each device */

1106  * iommu_unregister_device_fault_handler() - Unregister the device fault handler

1109  * Remove the device fault handler installed with

1146  * iommu_report_device_fault() - Report fault event to device driver

1148  * @evt: fault event data

1150  * Called by IOMMU drivers when a fault is detected, typically in a threaded IRQ

1151  * handler. When this function fails and the fault is recoverable, it is the

1152  * caller's responsibility to complete the fault.
