The ret needs to be set to zero on success. I'll send the fix shortly. Gurchetan you should've been getting the DRM_IOCTL_VIRTGPU_CONTEXT_INIT failure from gfxstream when you tested this patch, haven't you? Also noticed that the patch title says "drm/uapi" instead of "drm/virtio". My bad for not noticing it earlier. Please be more careful next time too :) -- Best regards, Dmitry
