    argo: Introduce the Kconfig option to govern inclusion of Argo
   
    Defines CONFIG_ARGO when enabled. Default: disabled.
   
    When the Kconfig option is enabled, the Argo hypercall implementation
    will be included, allowing use of the hypervisor-mediated interdomain
    communication mechanism.
   
    Argo is implemented for x86 and ARM hardware platforms.
   
    Availability of the option depends on EXPERT and Argo is currently an
    experimental feature.

+ ---help---
+  Enables a hypercall for domains to ask the hypervisor to perform
+  data transfer of messages between domains.
+
+  This allows communication channels to be established that do not
+  require any shared memory between domains; the hypervisor is the
+  entity that each domain interacts with. The hypervisor is able to
+  enforce Mandatory Access Control policy over the communication.
+
+  If XSM_FLASK is enabled, XSM policy can govern which domains may
+  communicate via the Argo system.
+
+  This feature does nothing if the "argo" boot parameter is not present.
+  Argo is disabled at runtime by default.
