For the e500 PV platform we need a VM reset and shutdown mechanisms.
------------------------------------------------------------------------
Hypercall: KVM_HC_VM_RESET
Description: Requests that the virtual machine be reset. The
hcall takes no arguments. If successful the hcall does not
return.
Arguments:
r11 hcall-token KVM_HC_VM_RESET
Return values
r3 status Status of the hcall. If the hcall succeeds
it does not return. If an error occurs
EV_INTERNAL is returned.
------------------------------------------------------------------------
Hypercall: KVM_HC_VM_SHUTDOWN
Description: Requests that the virtual machine be powered-off/halted.
The hcall takes no arguments. If successful the hcall does not
return.
Arguments:
r11 hcall-token KVM_HC_VM_SHUTDOWN
Return values
r3 status Status of the hcall. If the hcall succeeds
it does not return. If an error occurs
EV_INTERNAL is returned.
------------------------------------------------------------------------
Implementation notes:
-expect hcall token to be defined with KVM_HCALL_TOKEN:
KVM_HC_VM_RESET
KVM_HC_VM_SHUTDOWN
-the KVM_HC_FEATURES hcall should be expanded with new feature bits
to advertise both new hcalls to the VM: e.g. #define KVM_FEATURE_VM_RESET
