| 1 | What: legacy isochronous ABI of raw1394 (1st generation iso ABI) | ||
| 2 | Date: June 2007 (scheduled), removed in kernel v2.6.23 | ||
| 3 | Contact: linux1394-devel@lists.sourceforge.net | ||
| 4 | Description: | ||
| 5 | The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have | ||
| 6 | been deprecated for quite some time. They are very inefficient as they | ||
| 7 | come with high interrupt load and several layers of callbacks for each | ||
| 8 | packet. Because of these deficiencies, the video1394 and dv1394 drivers | ||
| 9 | and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created. | ||
| 10 | |||
| 11 | Users: | ||
| 12 | libraw1394 users via the long deprecated API raw1394_iso_write, | ||
| 13 | raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv | ||
| 14 | |||
| 15 | libdc1394, which optionally uses these old libraw1394 calls | ||
| 16 | alternatively to the more efficient video1394 ABI | ||
