similar to: [PATCH 1/3] virtio-gpu api: comment feature flags

The feature allows the guest request an EDID blob (describing monitor capabilities) for a given scanout (aka virtual monitor connector). It brings a new command message, which has just a scanout field (beside the standard virtio-gpu header) and a response message which carries the EDID data.

Introduce the concept of memory regions to virtio-gpu. Initially only memory regions composed of guest pages are supported (pretty much like current backing storage for resources). I expect support for other memory types will be added later on. VIRTIO_GPU_CMD_MEMORY_CREATE: creates a new memory region. VIRTIO_GPU_CMD_MEMORY_UNREF: destroys a memory region.

Add new command VIRTIO_GPU_CMD_RESOURCE_CREATE_V2 to create resources. It adds (a) support planar resources and (b) returns stride and size of the resource planes. The later will be needed in case we support mapping host resources into the guest some day.

This is to allow clients running within VMs to be able to communicate with a compositor in the host. Clients will use the communication protocol that the compositor supports, and virtio-gpu will assist with making buffers available in both sides, and copying content as needed. It is expected that a service in the guest will act as a proxy, interacting with virtio-gpu to support unmodified

From: Rob Clark <robdclark at chromium.org> Add a build option to disable modesetting support. This is useful in cases where the guest only needs to use the GPU in a headless mode, or (such as in the CrOS usage) window surfaces are proxied to a host compositor.
