menuconfig VIRT_DRIVERS
bool "Virtualization drivers"
help
Say Y here to get to see options for device drivers that support
virtualization environments.
If you say N, all options in this submenu will be skipped and disabled.
if VIRT_DRIVERS
config VMGENID
tristate "Virtual Machine Generation ID driver"
default y
depends on ACPI
help
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.
config FSL_HV_MANAGER
tristate "Freescale hypervisor management driver"
depends on FSL_SOC
select EPAPR_PARAVIRT
help
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.
