Virtual DRM splits the overlay planes of a display controller into multiple virtual devices to allow each plane to be accessed by each process. This makes it possible to overlay images output from multiple processes on a display. For example, one process displays the camera image without compositor while another process overlays the UI.
Updating the KMS state from multiple processes doesn't sound like a good idea. This opens up synchronization and global device limits issues.
Are you aware of DRM leasing?
