Add hypercalls to identify when Linux is running in a virtual machine under Gunyah. There are two calls to help identify Gunyah: 1. gh_hypercall_get_uid() returns a UID when running under a Gunyah hypervisor. 2. gh_hypercall_hyp_identify() returns build information and a set of feature flags that are supported by Gunyah.

Say Y here to use the hypervisor-provided Virtual Machine Generation ID
|
|
to reseed the RNG when the VM is cloned. This is highly recommended if
|

you intend to do any rollback / cloning / snapshotting of VMs.

Prefer Y to M so that this protection is activated very early.

The Freescale hypervisor management driver provides several services
|
|
to drivers and applications related to the Freescale hypervisor:
|
|
|
|
1) An ioctl interface for querying and managing partitions.
|
|
|
|
2) A file interface to reading incoming doorbells.
|
|
|
|
3) An interrupt handler for shutting down the partition upon
|
|
receiving the shutdown doorbell from a manager partition.
|
|
|
|
4) A kernel interface for receiving callbacks when a managed
|
|
partition shuts down.
