QVM Guest Shared Memory

guest_shm is a device that enables linux as a guest operating system

to allocate shared memory between virtual machines and send notifications

of updates to other virtual machines.

Required properties:

- compatible:		Must be "qvm,guest_shm".

- interrupt-parent:	Parent interrupt controller.

- interrupts:		Should contain QVM interrupt.

- reg:			Physical address of the guest factory and length.

Example:

	qvm,guest_shm {

		compatible = "qvm,guest_shm";

		interrupt-parent = <&gic>;

		interrupts = <6 4>;

		reg = <0x1c050000 0x1000>;

	};

* HAB

HAB(Hypervisor ABstraction) is meant to be a cross-platform abstraction layer

for utilizing the underlying hypervisor system. This API can be accessed from

both user and kernel sides.

The intended users of this are primarily the multimedia drivers who want to

communicate with the host OS to use the multimedia hardware.

Required properties:

- compatible: Must be "qcom,hab"

- vmid: the local VM's ID

  It should be unique in a system, and host's ID should be 0. Here is an

  example for a system as qvm host + agl gvm + android gvm, and such below

  setting is proper,

    qvm host's vmid: 0

    agl gvm's vmid: 1

    android gvm's vmid: 2

- mmid group properties:

  - grp-start-id: mmid group starting ID, eg, 100 is for MM_AUD_1~4

  - role: the local role of this group, and must be "fe" or "be"

  - remote-vmids: When the local role is "fe", this is to tell which VM is the

    relevant BE. When it is "be", this is to tell which VMs it will support as

    BE.

Example:

	qcom,hab {

		compatible = "qcom,hab";

		vmid = <2>;

		mmid100: mmid-grp@100 {

			grp-start-id = <100>;

			role = "fe";

			remote-vmids = <0>;

		};

		mmid200: mmid-grp@200 {

			grp-start-id = <200>;

			role = "fe";

			remote-vmids = <0>;

		};

	}
