The version in CVS is the pseudo version that just sleeps and simulates. My local version had a loop that calls an ioctl (doing idle waiting til the next interrupt and tells the field that got written). I didn't publish the patch so it wasn't useful to commit support for it in the v4l provider. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" Convergence GmbH -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
