Summary

Unlike the existing GLA2GPA ioctl, GLA2GPA_NOFAULT does not modify
the guest. In particular, it does not inject any faults or modify
PTEs in the guest when performing an address space translation.

This is used by bhyve's debug server to read and write memory for
the remote debugger.

Test Plan
  • used by the implemenation of 'm' in the debug server
