1What: legacy isochronous ABI of raw1394 (1st generation iso ABI)
2Date: June 2007 (scheduled), removed in kernel v2.6.23
3Contact: linux1394-devel@lists.sourceforge.net
4Description:
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
11Users:
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
