return -EINVAL in this case.
Additionally check if its already GH_RM_VM_STATUS_READY and return 0
in that
case.

Caller can use gh_vm_ensure_started for this behavior. I'll move this to
be used in the GH_VM_RUN ioctl as well.

Default value of auth is 0 (GH_RM_VM_AUTH_NONE). Is that what you
wanted here?
Perhaps initialize default value of auth to be
GH_RM_VM_AUTH_QCOM_PIL_ELF?
Yes, default VM is GH_RM_VM_AUTH_NONE.
