before anyone gets too excited, this doesn’t seem like it applies to DG2 gaming cards, ATSM and PVC are compute cards

+SR-IOV Capability
+=================
+
+Due to SR-IOV complexity and required co-operation between hardware, firmware
+and kernel drivers, not all Xe architecture platforms might have SR-IOV enabled
+or fully functional.
+
+To control at the driver level which platform will provide support for SR-IOV,
+as we can't just rely on the PCI configuration data exposed by the hardware,
+we will introduce "has_sriov" flag to the struct xe_device_desc that describes
+a device capabilities that driver checks during the probe.
+
+Initially this flag will be set to disabled even on platforms that we plan to
+support. We will enable this flag only once we finish merging all required
+changes to the driver and related validated firmwares are also made available.
+
+
+SR-IOV Platforms
+================
+
+Initially we plan to add SR-IOV functionality to the following SDV platforms
+already supported by the Xe driver:
+
+ - TGL (up to 7 VFs)
+ - ADL (up to 7 VFs)
+ - MTL (up to 7 VFs)
+ - ATSM (up to 31 VFs)
+ - PVC (up to 63 VFs)
+
+Newer platforms will be supported later, but we hope that enabling will be
+much faster, as majority of the driver changes are either platform agnostic
+or are similar between earlier platforms (hence we start with SDVs).
