IOMMU Fault Handling
This proposal has been accepted as a session.
One Line Summary
The IOMMU subsystem currently lacks fault propagation out to drivers or other users of the interface. We'll discuss work to be done in this area.
Abstract
Currently IOMMU fault handling is limited to the IOMMU driver, there’s no outbound notification path via either dma_ops or the IOMMU API. Most faults generate a dmesg log entry at best. In this discussion we’ll look at what the appropriate response should be for various use cases and how to get started with an implementation.
