Gurchetan Singh 7e78781df4 drm/virtgpu api: define a dummy fence signaled event ... The current virtgpu implementation of poll(..) drops events when VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK is enabled (otherwise it's like a normal DRM driver). This is because paravirtualized userspaces receives responses in a buffer of type BLOB_MEM_GUEST, not by read(..). To be in line with other DRM drivers and avoid specialized behavior, it is possible to define a dummy event for virtgpu. Paravirtualized userspace will now have to call read(..) on the DRM fd to receive the dummy event.
