As a heads-up, as this adds to the uAPI, this needs Acked-by from the respective userspace that will use the information, a link to the userspace change series and IGT test series all linked from the patch text. But as we're hoping to stay at version 1, I also would see that we only need to add this IOCTL if we get a version 2 of the tables. So there should be no need for this interface before we have some variance.
