libraw1394 Release Notes
|
|
|
|
Version 2.0.9:
|
|
- Fix that raw1394_iso_recv_flush() did not have any effect when running
|
|
on firewire-core alias juju kernel drivers. Requires kernel 3.4 or
|
|
later.
|
|
- Remove build-time dependency on linux-headers. Before, if too old
|
|
kernel headers were present on the build system, features and fixes
|
|
would be silently omitted from the build.
|
|
- Remove --with-fw-dir configure switch which is no longer useful.
|
|
- Janitorial fixes.
|
|
|
|
Version 2.0.8:
|
|
- Configuration ROM access via raw1394_read() is dramatically faster and
|
|
very robust now. We read the kernel's Configuration ROM cache instead
|
|
of the actual register of the FireWire device.
|
|
- Internally retry raw1394_read/write/lock/lock64() after ack-busy
|
|
response. Most notably this fixes control of some older Panasonic and
|
|
Grundig camcorders.
|
|
- small bug fixes
|
|
|
|
Version 2.0.7:
|
|
- Fix playback to some audio devices based on the DICE chipset.
|
|
|
|
Version 2.0.6:
|
|
- Bug fixes, notably for FCP and request reception on firewire-core.
|
|
Note, several of these updates are only built into libraw1394 if
|
|
linux-headers 2.6.36 or later are present at build time.
|
|
|
|
Version 2.0.5:
|
|
- Bug fixes, in particular, for isochronous transmission and FFADO project.
|
|
|
|
Version 2.0.4:
|
|
- Fix build due to incomplete tarball.
|
|
|
|
Version 2.0.3:
|
|
- various bug fixes, in particular for firewire stack
|
|
|
|
Version 2.0.2:
|
|
- Fixed license headers on new files introduced in v2.0.0 to be consistent
|
|
with LGPL v2.1.
|
|
|
|
Version 2.0.1:
|
|
- Optimized usage of /dev/fw? nodes based upon user permissions.
|
|
- many good bugfixes
|
|
|
|
Version 2.0.0:
|
|
- added support for new firewire subsystem.
|
|
- removed deprecated isochronous functions.
|
|
|
|
Version 1.3.0:
|
|
- added raw1394_read_cycle_timer() as used by FFADO project.
|
|
- added support for environment variable RAW1394DEV to override default
|
|
device node /dev/raw1394.
|
|
- added --with-valgrind to configure script.
|
|
- other optimizations and bugfixes - see ChangeLog.
|
|
|
|
Version 1.2.1:
|
|
- generate compiler warnings on deprecated functions (legacy isochronous).
|
|
- bugfixes and optimizations.
|
|
|
|
Version 1.2.0:
|
|
- added constants useful for ARM: transaction and response return codes.
|
|
- added raw1394_bandwidth_modify() and raw1394_channel_modify().
|
|
|
|
Version 1.1.0:
|
|
- added ability to specify the isochronous receive mode in the new
|
|
rawiso (raw1394_iso_*) API. Therefore, the signature of
|
|
raw1394_iso_recv_init() changed, and likewise, the libtool/.so version
|
|
numbers changed to reflect a new interface that is not backwards compatible!
|
|
- added raw1394_arm_set_buf() and raw1394_arm_get_buf() functions.
|
|
- added raw1394_new_handle_on_port() to make initialization simpler.
|
|
- make versioning consistent and updated. 1.0.0 was reported by pkg-config in
|
|
0.10 series; hence, 1.1.0 in this release.
|
|
- removed outdated, bogus "linking required only" version symbols in
|
|
version.c - use pkg-config now.
|
|
- dropped libraw1394.m4 - use pkg-config now.
|
|
- added RPM spec file.
|
|
- deprecate old isochronous API.
|
|
- move API comment documentation to header and reformat header comments as
|
|
kernel-doc (use linux/scripts/kernel-doc to extract and format them).
|
|
- updated tools/dumpiso and tools/sendiso to new isochronous API.
|
|
|
|
Version 0.10:
|
|
|
|
- merged in the rawiso branch
|
|
- add sendiso and dumpiso tools with man files
|
|
- fix wrong error mapping on local transactions in raw1394_errcode_to_errno().
|
|
- added comment headers for most exported functions
|
|
- merged in weihs branch which brings new functionality including address
|
|
range mapping, reading and writing configROM images, additional bus reset
|
|
handling, and others.
|
|
|
|
Version 0.9:
|
|
|
|
- error reporting reworked to be more C library style; functions affected are
|
|
mainly raw1394_read(), raw1394_write(), raw1394_lock;
|
|
Source incompatibility! Parts need to be adapted in application code, but
|
|
it's well worth it.
|
|
- the generation number is not unconditionally updated on bus reset in the event
|
|
loop anymore, the new function raw1394_update_generation() has to be used
|
|
(unless the default bus reset handler is used) so that transactions won't fail
|
|
- iso handlers used to get the iso header quadlet in host endian, now they get
|
|
it in big endian like the rest of the packet for consistency
|
|
- testlibraw gets installed now, man page also included
|
|
- (not yet complete) documentation in Docbook format included
|
|
- libraw1394.m4 autoconf macro added
|
|
|
|
Version 0.8:
|
|
|
|
- added libraw1394/ieee1394.h with useful defines (especially ack and rcodes)
|
|
- function to query isochronous resource manager ID
|
|
- functions for isochronous sending
|
|
- new raw1394_reset_bus() function to reset the bus
|
|
|
|
Version 0.7:
|
|
|
|
- added support for environments where the kernel runs in 64 bit mode whereas
|
|
user space runs in 32 bit mode
|
|
- fixed lock transaction to actually return the required response; these
|
|
functions are actually useful now, prototypes for raw1394_start_lock and
|
|
raw1394_lock changed
|
|
- a void pointer can now be stored as user data with a handle
|
|
|
|
Version 0.6:
|
|
|
|
- FCP monitoring added
|
|
- not really libraw1394 news: the subsystem doesn't swap data anymore,
|
|
everything is to be kept big endian now on all architectures
|
|
|
|
Version 0.5:
|
|
|
|
- there are now separate iso handlers for each channel
|
|
|
|
Version 0.4:
|
|
|
|
- isochronous receive support
|
|
|
|
Version 0.3:
|
|
|
|
- first release of new libraw1394 for new raw1394 driver
|
|
- supports 1394 async reads/writes
|
|
