5 | /dev/dv1394/* were character device files, one for each FireWire | ||

7 | could be received by read() or transmitted by write(). A few | ||

10 | libiec61883 which are functionally equivalent, support HDV, and | ||
11 | transparently work on top of the newer firewire kernel drivers. | ||

4 | Description: | ||
5 | /dev/raw1394 was a character device file that allowed low-level | ||
6 | access to FireWire buses. Its major drawbacks were its inability | ||
7 | to implement sensible device security policies, and its low level | ||
8 | of abstraction that required userspace clients do duplicate much | ||
9 | of the kernel's ieee1394 core functionality. | ||

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 | |||

16 | alternatively to the more efficient video1394 ABI | ||

4 | Description: | ||
5 | /dev/video1394/* were character device files, one for each FireWire | ||

7 | alternative to raw1394's isochronous I/O functionality which had | ||
8 | performance issues in its first generation. Any video1394 user had | ||
9 | to use raw1394 + libraw1394 too because video1394 did not provide | ||
