* Add raw1394_read_cycle_timer_and_clock() APIGravatar Stefan Richter 2012-06-181-3/+29
| | | | | | | | | | | | | | | | | | | This is an extension relative to raw1394_read_cycle_timer(). It lets the client choose a system clock other than CLOCK_REALTIME. Use case: http://subversion.ffado.org/ticket/242 The underlying ioctl supports reading the system clock with nanoseconds resolution. The new libraw1394 call sticks with microseconds resolution though. This makes transition from (or parallel use with) raw1394_read_cycle_timer() easier. Besides, the call itself takes longer than a microsecond, primarily due to a costly MMIO read (on many controllers even three or more MMIO reads). Unit tests with CLOCK_MONOTONIC and CLOCK_MONOTONIC_RAW are added to testlibraw as well. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* Tweak raw1394_add_config_rom_descriptor() API, add documentation and test caseGravatar Stefan Richter 2012-06-181-6/+57
| | | | | | | | | | | | | | | | | | | | To conform with 'size' arguments of other libraw1394 calls, change the one in raw1394_add_config_rom_descriptor() from quadlets to bytes. This breaks runtime compatibility with potential clients that were written against B.J.'s original patch, hence reorder arguments just to break compatibility also at compile time. Change errno to ENOSYS (function not implemented) when called while running on top of raw1394. Allow &token to be NULL for convenience of clients which don't require raw1394_remove_config_rom_descriptor(). Add exhaustive documentation. Much of it is copied from the documentation of the underlying ioctl. Add example code which doubles as unit test in testlibraw. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* Add raw1394_add_config_rom_descriptor() and ↵Gravatar B.J. Buchalter 2012-06-171-0/+9
| | | | | | | | | | | raw1394_remove_config_rom_descriptor() API This adds support of the firewire-core (juju) ABI to add and remove config ROM directories or descriptors. The raw1394 ABI supports similar requests, but for now we leave the two functions unimplemented when running on top of raw1394.

* Fix documentation of return values of raw1394_start_ family of functionsGravatar Stefan Richter 2010-02-011-7/+7
| | | | | | | | | | | | | | | | | | | If running on top of the raw1394 kernel driver (any kernel version) or on top of firewire-core (kernel version <= 2.6.29), raw1394_start_* functions will return a value > 0 on success, not == 0. Only with firewire-core of kernel 2.6.30 or later, == 0 is returned on success. The exact value depends on which driver is used, on CPU architecture, and on request payload size in case of some types of requests. In any case, only that the value is > or == 0 on success (but == -1 on failure) is significant to libraw1394 client applications. This mismatch between documentation and implementation was already present in older libraw1394 versions, including v1.x. For the time being, do not change the implementation, only adjust the documentation. Reported-by: Dr. David Alan Gilbert Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
* Fix "make doc".Gravatar Stefan Richter 2010-01-101-11/+7
| | | | | | | | | | | | | | | | | | | | Reported by Guus Sliepen: "make doc" failed due to missing doctype, unknown elements, and duplicate element IDs in libraw1394.sgml. The fix is to declare a recent DTD (matching the one which is used in current Linux kernel documentation docbooks) and to make the conflicting element IDs unique. The latter part of the fix is just temporary. In order to avoid the conflict when the documentation is updated the next time, also fix the kerneldoc comments of the respective API elements: These are typedefs, hence kernel-doc needs their comments prepended by "typedef ". Tested with Gentoo's docbook-xml-dtd 4.5, docbook-xsl-stylesheets 1.75.2, docbook-sgml-utils 0.6.14, and openjade 1.3.2-r1.

* [libraw1394 patch] Fix raw1394_channel_modify() on firewire-coreGravatar Stefan Richter 2008-12-031-1/+1
| | | | | | | | | | | | | | | | | | | (juju) Reported by Adrian Knoth: fw_channel_modify() was unable to allocate some channels which were actually free. http://marc.info/?l=linux1394-devel&t=122818128900002 This can be easily fixed by replacing fw_channel_modify() by ieee1394_channel_modify() because this is highlevel enough to work with Juju as well. We only may want a separate fw_channel_modify() in the future when firewire-core gains a special ioctl() for that. Also fix a documentation typo: raw1394_channel_modify() did not show up in extracted API documentation due to a cut'n'paste typo in raw1394.h.

* Added a new callback response for iso_xmit handlers: RAW1394_ISO_AGAIN.Gravatar ddennedy 2006-03-041-0/+5
| | | | | | | | | | | | | | | This would be returned when the callback doesn't have enough data to create a complete packet. This can occur when the xmit buffers are bigger than the buffers supplying the data. It is not nescessarily an error, because there are enough packets in the xmit buffer. This response could give the data supplyer more time to fill the intermediate buffer without losing any packets.
