I saw the patch failed to be applied so figured the email mangled it. I sent
another email of the patch as plain text so hopefully that will work better.
Sorry for the duplicate submission but I didn't have this email thread yet to
respond to. How would you like to continue this discussion
We only support the most recent two versions of macOS (currently
macOS 13 Ventura and macOS 14 Sonoma), and our ui/cocoa.m code
already assumes at least macOS 12 Monterey or better, because it uses
NSScreen safeAreaInsets, which is 12.0-or-newer.

As the SVM-capable devices will need to cache translations, we provide
an first implementation.
This cache uses a two-level design based on hash tables.
The first level is indexed by a PASID and the second by a virtual addresse.

Devices can use IOMMU_TLB_ENTRY_TRANSLATION_ERROR to check the tlb

We add a convenient way to initialize an device-iotlb notifier.
This is meant to be used by ATS-capable devices.
pci_device_iommu_memory_region_pasid is introduces in this commit and
will be used in several other SVM-related functions exposed in
the PCI API.

Implements the behavior defined in section 10.2.3.5 of PCIe spec rev 5.
This is needed by devices that support ATS.

What wrong values? The values in the dtb should match the

Devices implementing ATS can send translation requests using
pci_ats_request_translation_pasid.
The invalidation events are sent back to the device using the iommu

The 'level' field in vtd_iotlb_key is an uint8_t.
We don't need to store level as an int in vtd_lookup_iotlb (avoids a
'loosing precision' warning).
VTDIOTLBPageInvInfo.mask is used in binary operations with addresses.

This will be necessary for devices implementing ATS.
We also define a new macro IOMMU_ACCESS_FLAG_FULL in addition to
IOMMU_ACCESS_FLAG to support more access flags.
IOMMU_ACCESS_FLAG is kept for convenience and backward compatibility.

Add xlnx_dpdma_read_descriptor() and
xlnx_dpdma_write_descriptor() functions.
xlnx_dpdma_read_descriptor() combines reading a
descriptor from desc_addr by calling dma_memory_read()
and swapping the desc fields from guest memory order
to host memory order. xlnx_dpdma_write_descriptor()
