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).
