	  The Gunyah drivers are the helper interfaces that run in a guest VM
	  such as basic inter-VM IPC and signaling mechanisms, and higher level
	  services such as memory/device sharing, IRQ sharing, and so on.

	  Say Y/M here to enable the drivers needed to interact in a Gunyah
	  virtual environment.

	  Enable support for interacting with Gunyah on Qualcomm
	  platforms. Interaction with Qualcomm firmware requires
	  extra platform-specific support.

	  Say Y/M here to use Gunyah on Qualcomm platforms.

config GUNYAH_VCPU

	  Enable kernel support for host-scheduled vCPUs running under Gunyah.
	  When selecting this option, userspace virtual machine managers (VMM)
	  can schedule the guest VM's vCPUs instead of using Gunyah's scheduler.
	  VMMs can also handle stage 2 faults of the vCPUs.

	  Say Y/M here if unsure and you want to support Gunyah VMMs.

config GUNYAH_IRQFD
	tristate "Gunyah irqfd interface"
	depends on GUNYAH
	help
	  Enable kernel support for creating irqfds which can raise an interrupt
	  on Gunyah virtual machine.

	  Say Y/M here if unsure and you want to support Gunyah VMMs.

config GUNYAH_IOEVENTFD
	tristate "Gunyah ioeventfd interface"
	depends on GUNYAH
	help
	  Enable kernel support for creating ioeventfds which can alert userspace
	  when a Gunyah virtual machine accesses a memory address.

	  Say Y/M here if unsure and you want to support Gunyah VMMs.
