◆ ReleaseGopResources()

VOID ReleaseGopResources	(	IN OUT VGPU_GOP *	VgpuGop,
		IN BOOLEAN	DisableHead
	)

Release guest-side and host-side resources that are related to an initialized VGPU_GOP.Gop.

param[in,out] VgpuGop The VGPU_GOP object to release resources for.

                   On input, the caller is responsible for having called
                   VgpuGop->Gop.SetMode() at least once successfully.
                   (This is equivalent to the requirement that
                   VgpuGop->BackingStore be non-NULL. It is also
                   equivalent to the requirement that VgpuGop->ResourceId
                   be nonzero.)

                   On output, resources will be released, and
                   VgpuGop->BackingStore and VgpuGop->ResourceId will be
                   nulled.

param[in] DisableHead Whether this head (scanout) currently references the resource identified by VgpuGop->ResourceId. Only pass FALSE when VgpuGop->Gop.SetMode() calls this function while switching between modes, and set it to TRUE every other time.
