• bc21662f7   iommu/amd: Add invalidate-context call-back ... Browse Code »

  This call-back is invoked when the task that is bound to a
  pasid is about to exit. The driver can use it to shutdown
  all context related to that context in a safe way.

• 8736b2c33   iommu/amd: Implement notifiers for IOMMUv2 ... Browse Code »

  Since pages are not pinned anymore we need notifications
  when the VMM changes the page-tables. Use mmu_notifiers for
  that.
  Also use the task_exit notifier from the profiling subsystem
  to shutdown all contexts related to this task.

  Add a Kconfig option for the optional driver. Since it is
  optional it can be compiled as a module and will only be
  loaded when required by another driver.
