| 2024-04-26 | iommu/vt-d: Remove debugfs use of private data field | Jingqi Liu | |
| Since the page fault report and response have been tracked by ftrace, the users can easily calculate the time used for a page fault handling. There's no need to expose the similar functionality in debugfs. Hence, remove the corresponding operations in debugfs.

| 2021-06-10 | iommu/vt-d: Add common code for dmar latency performance monitors | Lu Baolu | |
| The execution time of some operations is very performance critical, such as cache invalidation and PRQ processing time. This adds some common code to monitor the execution time range of those operations. The interfaces include enabling/disabling, checking status, updating sampling data and providing a common string format for users.
