Function framebuffer

pub fn framebuffer(
    vram: Mappable,
    len: usize,
    offset: u64,
) -> Result<(Framebuffer, FramebufferAccess)>

Creates a framebuffer and an object that can be used to read from it. The framebuffer should be allocated prior to calling this function.

• vram: [Mappable] (OwnedFd/OwnedHandle) that can be mapped into guest memory and a SparseMapping for the VNC server to read from. In HvLite, this is created by alloc_shared_memory. In Underhill, this is /dev/mshv_vtl_low.

• len: The amount of memory that was allocated for the framebuffer.

• offset: The file_offset that should be used when reading the framebuffer. In HvLite, this should be 0. In Underhill, this is the GPA of the VTL2 framebuffer mapping.
