It returns 1 if the stream is not full (so that we can continue send
something), otherwise 0.
Generally, it's used like:

This patch is based on Aviv Ben-David ()'s patch

"IOMMU: enable intel_iommu map and unmap notifiers"

We have a specific memory region for DMAR now, so it's wrong to
trigger the notifier with the root region.

This is preparation work to finally enabled dynamic switching ON/OFF for
VT-d protection. The old VT-d codes is using static IOMMU address space,
and that won't satisfy vfio-pci device listeners.
Let me explain.
vfio-pci devices depend on the memory region listener and IOMMU replay
mechanism to m
Originally we have one memory_region_iommu_replay() function, which is
the default behavior to replay the translations of the whole IOMMU
region. However, on some platform like x86, we may want our own replay
logic for IOMMU regions. This patch add one more hook for IOMMUOps for
the callback, and i
The default replay() don't work for VT-d since vt-d will have a huge
default memory region which covers address range 0-(2^64-1). This will
normally consumes a lot of time (which looks like a dead loop).
The solution is simple - we don't walk over all the regions. Instead, we
jump over the regions
In this patch, IOMMUNotifier.{start|end} are introduced to store section
information for a specific notifier. When notification occurs, we not
only check the notification type (MAP|UNMAP), but also check whether the

and skip th
Generalizing the notify logic in memory_region_notify_iommu() into a
