Is there any documentation on how QEMU communicates with KVM?

There are several ways that qemu and kvm can communicate.
One of them is the ioctl to /dev/kvm and it is documented in Documentation/virtual/kvm/api.txt.
But there's other ways also: like the pages that are mmap-ed from kvm_vcpu_fault function,
As far as I know, there is no documentation on such communication channel(but i'm not sure)
