Probably the same exact design as the PCIe ones, minux the xHCI USB3 controller. Middle chip would be VS9989, so second leg not MIPI-CSI but also parallel video. http://www.vxis.com/html/pdf/VS9989_bf_v1.3.pdf …pic.twitter.com/HjYT3CKy3Z

Everything is separate on my lowly old Ivy Bridge laptop. Doesn't get much better than this, and this is basically crap Intel consumer mobile gear. You don't need a P9 to get isolation like this.pic.twitter.com/OH7LXgqEsg
Obviously multifunction devices are grouped, as are the discrete GPU and its corresponding root port, but that's okay. The only fail is that the Intel iGPU is not IOMMUed at all, but that's to be expected in this generation.

Well, regardless I do recall people having trouble on x86 systems after enabling it, so these controllers are problematic, or at least their firmware is (but, ultimately it doesn't matter which, afaik it's not user accessible on most of these)

Also, aren't most onboard peripherals provided directly off the chipset in x86 systems nowadays?
