Just a word of warning file_priv->pid isn't a true indicator of the attached process's pid. E.g. DRI3 passes the struct drm_file over a UNIX socket, so pid is Xorg but the actual process is the GL client. Not sure if we can detect the transfer over the socket, but one suggestion has been to update file->pid based on who creates a context. -Chris _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
