Intel vPro CPUs with iGPUs are used by the Fortune 500 enterprise industrial base. Intel hardware is already segmented for enterprise markets and they enable/disable features for specific markets.

There's lots of hardware competition for consumers, including upcoming Arm laptops from Mediatek and Nvidia. Intel can use feature-limited SKUs in both CPUs and GPUs to target specific markets with cheaper hardware and reduced functionality.

I'd wager it's a volume thing. Not enough Linux customers asking for SRIOV support, so it's not worth spending the money to enable driver support for it. The Fortune 500 companies that you mention should specifically ask for SRIOV support on linux mainline when making purchases. Unfortunately, that's the only way to make sure we have support upstreamed.

The silver lining seems to be that more and more things are moving into the firmware, and it's entirely possible that SRIOV could be supported through that in the future. But till then, I doubt it's going to happen.
