Subject[PATCH v4 0/2] iommu: Add iommu_error class event to iommu trace
Date
This patch set adds iommu_error class event to iommu trace. iommu_error class
event can be enabled to trigger when an iommu error occurs. This trace event
is intended to be called to report the error information. Trace information
includes driver name, device name, iova, and flags.

iommu_error:io_page_fault

This patch set depends on the previous patch set that added iommu tracing
feature. Reference:
