* ieee1394: ohci1394: increase AT req. retries, fix ack_busy_X from Panasonic ↵Stefan Richter2009-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | camcorders and others Camcorders have a tendency to fail read requests to their config ROM and write request to their FCP command register with ack_busy_X. This has become a problem with newer kernels and especially Panasonic camcorders, causing AV/C in dvgrab and kino to fail. Dvgrab for example frequently logs "send oops"; kino reports loss of AV/C control. I suspect that lower CPU scheduling latencies in newer kernels made this issue more prominent now. According to https://sourceforge.net/tracker/?func=detail&atid=114103&aid=2492640&group_id=14103 this can be fixed by configuring the FireWire controller for more hardware retries for request transmission; these retries are evidently more successful than libavc1394's own retry loop (typically 3 tries on top of hardware retries). Presumably the same issue has been reported at https://bugzilla.redhat.com/show_bug.cgi?id=449252 and https://bugzilla.redhat.com/show_bug.cgi?id=477279 .

* ieee1394: remove old isochronous ABIStefan Richter2007-07-09
| | | | | | | | | | | | | | | | | | | Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}" from Adrian Bunk, November 20 2006. This patch also removes the underlying facilities in ohci1394 and disables them in pcilynx. That is, hpsb_host_driver.devctl() and hpsb_host_driver.transmit_packet() are no longer used for iso reception and transmission. Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso interface has never been implemented in pcilynx, pcilynx is now no longer useful for isochronous applications. raw1394 will still handle the request types but will complete the requests with errors that indicate API version conflicts.

* ohci1394: set address range propertiesBen Collins2006-06-12
| | | | | | | | | | | | | | | | | | | | | | | This patch supplies the API extension introduced by patch "ieee1394: extend lowlevel API for address range properties" with proper addresses. Like in patch ''ohci1394, sbp2: fix "scsi_add_device failed" with PL-3507 based devices'', 1 TeraByte is chosen as physical upper bound. This leaves a window for the middle address range. This choice is only relevant for adapters which actually have a programmable pysical upper bound register. (Only ALi and Fujitsu adapters are known for this. Most adapters have a fixed bound at 4 GB.) The middle address range is suitable for posted writes. AFAIK, PCILynx does not support physical DMA nor posted writes, therefore no equivalent change in the pcilynx driver is necessary. There is also a driver for GP2Lynx, although not in mainline Linux. I assume this hardware does not support these OHCI features either. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Ben Collins <bcollins@ubuntu.com>
* Remove amdtp, cmp drivers.Jody McIntyre2005-11-18
| | | | | | | | | | Remove the Audio and Music Data Transmission Protocol driver and the Connection Management Procedures driver. These are incomplete, have never worked, and are better implemented in userland via raw1394 (see http://freebob.sourceforge.net/ for example.)

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
