QNX Neutrino 6.6 documentation online

• The create and modify commands now have a -m option that lets you specify the maximum CPU time, in percent, that the partition may consume if it has no competition.
• The list of scheduling policies for the -S option now includes partition_local_priorities, limit_cpu_usage, and no_long_reporting.

You can use the -display option to specify the display you want to calibrate; this option is required when you are configuring multiple touchscreens.

You can use the -exit-on-timeout option to specify that calib-touch shouldn't restart when it detects a period of inactivity.

• Note that the startup must set up the typed memory regions that you refer to with the mem name= option for devb-ahci.
• We've documented the pwrdwn option.
• We've added more details about the smart option.

• cam:
  • lun

• We've documented the following options:
  • -l — set the level of output verbosity.
  • -U string — run as the user specified in string.
• The sw_mixer_samples option now specifies the number of samples per channel. The default value is now 1024.
• The default value for config_write_delay is now -1, which prevents the settings from ever being written.
• (QNX Software Development Platform 6.6 io-audio patch [patch ID 4687] or later) If you specify an ampersand (&) before the key name in a configuration file, the value is appended to the key's current value.

  • the maxio option, which lets you limit the size of I/O requests that io-blk.so composes and hands over to the CAM library.

• mfib_gid_map=string
• stackguard

• -p

We've documented the following options:

• -l
• -M

• We've documented the -D, -d, and -o options.

• You must use the num_blocks attribute to specify the number of blocks in the flash device; you can also use it to specify the minimum number of blocks to include in the image file.
• We've documented the -D and -d options.
• We've clarified the behavior of the -followlink attribute.

• By default, mkifs doesn't strip .gnu_debuglink sections from ELF files.

• If you specify the -w option, on exits with a status of 0 on success, or a nonzero value if a timeout occurred.
• We've documented the able= value that you can use with the -A option to specify the ID of a dynamic ability.

• The -c option takes a numeric argument that indicates which device classes to ignore.
• Note that for pci-bios-v2, MSI and MSI-X by default are disabled for video devices, and enabled for other devices. Specifying -M disables all the MSI and MSI-X interrupts, even those for video. The -D option has no effect if you specify -M.

• There's a new j formatting code that displays the set of blocked signals.
• We've explained the difference between the free memory and actual free resident memory numbers displayed by the pidin info command.
• We've documented the new _DEBUG_FLAG_EXEC and _DEBUG_FLAG_THREAD_EV process debug flags.
• We've documented the _NTO_PF_WAITDONE and _NTO_PF_TERM_WAITING process flags.
• We've documented the new _NTO_PF_ASLR and _NTO_PF_EXECED process flags.

• The default handling for alignment faults (the -as option) is now -ae for all supported platforms.
• We've documented the following options and memory configuration options:
  • -d — specify the umask to use when creating the entries in /proc/pid/ctl.
  • -S — specify the number of bytes after and (optionally) before the stack pointer to include in a kernel dump.
  • -m[~]g — add (or don't add) a guard page before any shared memory allocations.

• We've improved the description of the -P option.
• If you specify a value for the -S option that's zero or greater than UINT_MAX, it's ignored.
• If you specify 0 for the -T option, the default of 30 seconds is used.

• -a
• -l
• bind=bind_address

• You can now have multiple routes to the same destination.
• We've documented the -d, -S, -s and -t options.

• -F
• -O

• -u

• -i
• -P
• -p
• -r
• -w

• We've documented the -k and -w options.
• After sending a SIGTERM signal to a process, this utility sends a SIGCONT signal, in case the process had earlier been stopped.

• If you want to redirect syslogd output to slogger, edit /etc/syslog.conf and specify an action to send the log messages to /dev/console, or specify the LOG_CONS flag when you call openlog().
• You can't redirect slogger output to slogger2 in general, but if a program uses the slogger APIs, you can preload the libslog2shim.so library when you start the program, in order to redirect its logs.
• The size argument for the -l option is in kilobytes.

• Note that if you specify a pathname for an action, the file must exist when syslogd reads its configuration file. Otherwise the action is ignored.
• If you want to redirect syslogd output to slogger, specify an action to send the log messages to /dev/console, or specify the LOG_CONS flag when you call openlog().

• 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.
• We've documented the -D option.
• For the -f option, if file is a hyphen (-), then the logged events are streamed to stdout. If file names an existing FIFO special file created with mkfifo() or the mkfifo utility, the logged events are streamed to the FIFO.

• -a
• -D

• -b — specify the number of fragments while buffering
• -d (QNX Software Development Platform 6.6 io-audio patch [patch ID 4687] or later) — continuously repeat the input file.
• -e — the content would like to be played on a secure channel
• -o — the name of the audio type registers with audioman
• -R — the SRC rate method
• -r — the content can be played only on a secure channel.

You can now use the -c option to set the voice matrix configuration for up to eight voices.

• We now ship this utility for x86 and ARMLE-v7.
• We've updated the list of options.

• We've corrected the forms of the -U option's argument.
• We've corrected the descriptions of the -N and -n options.

• The length of the key depends on the type of encryption; see the description of the -t option.
• In order for you to tag files for migration, the source and destination domains must be unlocked.
• A domain doesn't have to be unlocked for you to delete it.
• We've corrected the descriptions of the .[salt.]str and #str forms of the -k option.
• You must use the -t option to specify the type of encryption when you use the change-key, check-key, unlock, and write-key commands.
• You can specify a domain of 0 (using the -d option) to remove encryption.
• If you assign a domain to a directory or empty file, the domain replaces any domain previously assigned to the path.

• We've expanded the description of the dperms, mountperms, and perms attributes. The symbolic modes for these attributes are similar (but not identical) to the symbolic modes for chmod.
• If you specify dperms=* for an inline directory, the permissions are 0755 (rwxr-xr-x).
• We've corrected the example for mkqnx6fsimg.

• This utility runs on QNX Neutrino, not on development hosts.
• You must specify the -f and -m options.

• If you want new() to return NULL instead of throwing an exception, you can provide a custom new handler via std::set_new_handler() to do so, or use std::nothrow.
• The -nostdlib option makes qcc not use the ld_startup_* or ld_stdlib sections.

• We've corrected the names of the PROCMGR_EVENT_PATHSPACE and PROCMGR_EVENT_DAEMON_DEATH system events.
• The default value for the -r option is replace.

• You shouldn't launch this daemon from inetd because the limit on the rate of creating server instances (specified with the max field in inetd.conf) could limit the number of connections and cause them to be denied.
• You need to create ECDSA host keys in addition to RSA and DSA ones.
