Changed content
- chkqnx6fs
- You should run chkqnx6fs only on an unmounted filesystem.
- fs-qnx6.so
- We've described the certicom and openssl values for the crypto option.
- getconf
- There's a new _CS_CONFIG_PATH configuration string.
Its value is a colon-separated list of directories to search for configuration files.
- io-audio
- Audio configuration file changes:
- [GLOBAL] and [CTRL] sections:
- added sw_mixer_sample_size
- [CTL] section:
- added input_splitter_ms
- added input_splitter_rate
- [AFM] section:
- added local_rate_default and
local_rate_mode
- added remote_rate_default and
remote_rate_mode
- io-blk.so
- We've added more information about the naming option and how it affects
the maximum number of partitions.
- mkefs,
mketfs,
mkfatfsimg,
mkifs,
mkqnx6fsimg
- These utilities have new cksum and sha256 attributes.
- mkifs
-
- By default, mkifs doesn't strip .gnu_debuglink sections from
ELF files.
- We've documented the keepsection attribute.
- mqueue
- The /dev/mqueue directory now appears as soon as you start mqueue.
- pidin
-
- We've explained the difference between the free memory and actual free resident memory numbers
displayed by the pidin info command.
- The amount of information that this utility provides depends on which abilities are enabled.
- ping6
- We've documented the -m and -t options.
- procnto*
-
- There's a new -s option that enables safe shared mutexes;
the kernel rejects any attempts to lock priority-impacting mutexes whose owner isn't known to the kernel and that
the locking thread claims is from a different process.
If you use this option, you should set the process-shared attribute to PTHREAD_PROCESS_SHARED
for any barriers, condition variables, mutexes and read-write locks that are shared between processes.
- You can now specify a tilde (~) to clear some boolean options.
The -fe, -h, -p, and -v options
now support this feature.
- There's a new /proc/config virtual file that summarizes the configuration settings
for procnto*.
- slm
- The SLM component tag now supports the ability and type tags
- tracelogger
-
- Note that if an application has called TraceEvent(_NTO_TRACE_START), and you then try to
start tracelogger, tracelogger might fail with a “resource busy” message.
- When you terminate tracing in ring mode, tracelogger stops logging events,
and then briefly starts it again so it can capture the state information that's emitted by the
_NTO_TRACE_START command.
- uname
- If you're running a safety version of the kernel, the release level (the output for the
-r option) now includes an uppercase “S”.
- valgrind
- The utility reference now explains how to make shared libraries and debug symbols available on the target.
Errata
- mkifs
- The t permission in the perms attribute indicates that the file
should be executed in place.
- mq
- The /dev/mq directory appears as soon as you start mq.
- tracelogger
- The -E option enables events, even if you're running in daemon mode.
