Had a bit more of a poke and traced kvm and qxl on both machines at 
approximately comparative times of the same benchmark. From what I can 
ascertain in this context ioctl type 0xc008ae67 is KVM_IRQ_LINE_STATUS.

The i7 trace shows maybe 10ms spent hitting that. The Ryzen trace below shows 
the majority of the frame spent hitting that ioctl (some ~110ms).

i7 :
