Subject: [PATCH v2 04/12] iommu: Replace device fault handler with iommu_queue_iopf()
Date: Thu, 27 Jul 2023 13:48:29 +0800 [thread overview]
Message-ID: <20230727054837.147050-5-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20230727054837.147050-1-baolu.lu@linux.intel.com>
The individual iommu drivers report iommu faults by calling
iommu_report_device_fault(), where a pre-registered device fault handler
is called to route the fault to another fault handler installed on the
corresponding iommu domain.
The pre-registered device fault handler is static and won't be dynamic
as the fault handler is eventually per iommu domain. Replace calling
device fault handler with iommu_queue_iopf().
