| What: legacy isochronous ABI of raw1394 (1st generation iso ABI) |
| Date: June 2007 (scheduled), removed in kernel v2.6.23 |
| Contact: linux1394-devel@lists.sourceforge.net |
| Description: |
| The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have |
| been deprecated for quite some time. They are very inefficient as they |
| come with high interrupt load and several layers of callbacks for each |
| packet. Because of these deficiencies, the video1394 and dv1394 drivers |
| and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created. |
| |
| Users: |
| libraw1394 users via the long deprecated API raw1394_iso_write, |
| raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv |
| |
| libdc1394, which optionally uses these old libraw1394 calls |
| alternatively to the more efficient video1394 ABI |
