What's new in QNX Neutrino 6.5.0?

The key improvements in 6.5.0 include:

For more details, see the following sections:

Migrating from earlier releases

APIC-enabled devices

This release provides better support for Advanced Programmable Interrupt Controller (APIC) chipsets. Some newer systems contain APIC chipsets and may not run with the provided release package. If you are using a computer that supports APIC chipsets, you should download and install the APIC-enabled Neutrino ISO from the QNX Software Development Platform 6.5.X folder in download center located at: http://www.qnx.com/download/group.html?programid=20905

Note: This ISO image boots using startup-apic and pci-bios-v2 and will install a new boot image called qnxbasesmp-apic.ifs. This is the default image for normal booting.

If you've installed the SDP from the x86-only CD, or if you've installed using the APIC-enabled version of the x86-only CD from the download center and you want to target non-X86 platforms for development, you must manually install the non-x86 targets. To install the non-x86 targets:

  1. After you have installed Neutrino, you can retrieve the non-x86 packages from the download center. If you installed from the CD, but your system has a DVD drive (for example, you require APIC support), then you can insert the DVD.

    Note: Use /fs/cd0/repository as the source path below; otherwise you must manually transfer the packages from the DVD. Place the files in a location on your local file system. This is your source path.

  2. Change to /usr/qnx650.
  3. For each of the following files: qnx6-host.tarx, qnx6-target.tarx, and qnx6-target-gpl.tarx, run the following:
    qinst d /fs/cd0/repository/FN | tar -zx -f-

    where FN is a qnx6xxx.tarx file above.

What's new: Kernel

You can now set the tracing mode to fast or wide for specific events in the _NTO_TRACE_THREAD class. You can also do this for events in the _NTO_TRACE_PROCESS and _NTO_TRACE_VTHREAD classes, but there's currently no difference between the data for fast and wide mode for these classes. (Ref# 69613)
If this bit is set in the flags member of the system page's cpuinfo table, the processor supports Power ISA 2.06 External Process ID Registers, which the kernel uses to optimize the passing of messages between different address spaces.

Note: The Freescale e500mc is currently the only PPC to implement these features; it's the only processor for which you should set this flag. Setting it on other processors will have unpredictable results.

QNX Neutrino for ARMv7 Cortex A-9 Processors
You can now set up QNX Neutrino for boards that support ARMv7 Cortex A-9 processors. Although the ARMv7 generic support was included in QNX SDP 6.4.1 when the initial Cortex A-8 support was released, the CPU implementations for both Cortex A-8 and Cortex A-9 are included in the QNX SDP 6.5.0 release.

For more information, see the QNX Neutrino for ARMv7 Cortex A-8 and A-9 Processors technote in the online documentation.

Persistent Publish/Subscribe (PPS)

Persistent Publish/Subscribe (PPS) is a resource manager that takes control of part of the file namespace to make information available to interested processes:

For more information, see the PPS Developer's Guide in the online documentation.

What's new: Licensing

QNX SDP 6.5.0 introduces a new licensing scheme:

Once you've installed the QNX Software Development Platform, you can find all the license agreements in base_dir/install/qnxsdp/6.5.0, where base_dir is where you installed SDP (see the output from the qconfig command).

For more information about license agreements, see the Licensing area of http://www.qnx.com, or email .

What's new: Installing and booting

What's new: Startup

New utilities include:

Provide support for the PCI BIOS and Message Signaled Interrupts (MSI). (Ref# 69146, 74069)
Startup for Intel Advanced Programmable Interrupt Controller (APIC) systems (Ref# 69146, 74069)

  • If you plan to use more than 8 CPUs on an x86 platform, you must use the 6.5 version of procnto-smp and startup-bios or startup-apic. (Ref# 75180)
  • If you're running startup-apic, you must use pci-bios-v2 instead of pci-bios, but it must still be called pci-bios in order for the enumerators to work correctly. In your buildfile, add pci-bios-v2 like this:

What's new: Core networking

As part of the update to BIND 9.6.1-P2 (see What's new: Security,” below), we now support:

DNSSEC Delegation Signer resource record generation tool
DNSSEC key generation tool

Other changes include the following:

The behavior of pwrite() is now consistent with that on other Neutrino filesystems. If you open a file with O_APPEND, pwrite() now writes the data at the offset supplied, instead of at the end of the file. (Ref# 38576)
io-pkt-v4, io-pkt-v4-hc, io-pkt-v6-hc
There's a new TCP/IP pkt_typed_mem option that you can use to specify a typed memory object to allocate packet buffers from. (Ref# 73666, 74355)
SSH suite
We now use OpenSSL version 0.9.8m. For more information, see http://www.openssl.org/. (Ref# 74597)
If you use pppd with a serial port, io-pkt no longer becomes reply-blocked. (Ref# 50977, 68456)

What's new: Filesystems

io-blk.so redesign

We've redesigned the buffer cache subsystem of io-blk.so, in order to improve performance. The main changes include:

Performance gains were measured on all platforms: on desktop x86 systems, where the bottleneck was the device, the same throughput is observed but using less CPU load (e.g. 10-25%); on low-end ARM systems, where the bottleneck was OS and memory overheads, the same CPU load achieves greater filesystem throughput (e.g. 2-10 MB/s). Larger cache granularity may require more cache to be allocated at the lower-end (reduced hit density during random operations) although this is mitigated by lower control/overheads (same overall usage).

As a result of this redesign, the following options to io-blk.so are no longer supported:

The following options are new:

Other changes include:

(Ref# 69116, 69788, 72369, 74621, 75622)

Other filesystem changes

Other changes to the filesystems include:

This utility has several new options: (Ref# 68671, 68705, 68911, 69178, 70467)
The fatchk option is no longer supported. (Ref# 69116, 74719)
We've changed the ignore value for the sync option to none, in order to make its meaning clearer. If you specify sync=none, the filesystem never issues a synchronization command to the disk, and doesn't drain dirty blocks from the filesystem cache (until an explicit umount). The filesystem still supports the ignore value too. (Ref# 54873, 72991)
New options include:

The blacklist for the verify option now includes some bad ISO9660:1999 SVD-mastering utilities.

What's new: Graphics

Advanced Graphics

New features include:

There's a new -g option that lets you specify the GFI input group to attach to. (Ref# 70808, 74360)
Get the handle of the graphics device currently targeted by a surface (Ref# 69915)

Other changes include:

gf_draw_finish(), gf_draw_flush()
Improvements have been made to these functions with respect to drivers that don't require layer_flushrect() updates. If your applications is linked statically against libgf.a, we strongly recommend that you relink your application. (Ref# 68760)

Composition Manager

After 6.5.0, QNX Composition Manager will no longer be included as part of QNX SDP. The current version of QNX Composition Manager will be deprecated. A replacement product will be provided as part of a separate product suite called QNX Screen.

gles1-egl-gears, gles1-kd-gears
These demos no longer support the rotation option. (Ref# 73537)

Photon microGUI

New features include:

Rotating the display
Display rotation is again available in the Photon environment. Available rotations are 90, 180, and 270 degrees. You can rotate the display by using a “phook” module (DLL) loaded by io-graphics. You can add a phook statement to the display.conf configuration file, in the appropriate driver's photon section, as follows:

where * is 90, 180, or 270.

There's a new -C command-line option for io-graphics that causes all client-side surfaces to be allocated for CPU Fast Access. This is important in a system that will use a rotation module, since access to the framebuffer is required, and without this option, access will be made over the bus, introducing serious latency.

There's also a new -L option for io-graphics that forces a PHOOK module to initialize, even if the GPU driver was written with non-linear framebuffer access.

If you're using the ph script to start Photon, you can easily apply this option before Photon is started, by overriding the PHGFX environment variable like this:

  export PHGFX="/usr/photon/bin/io-graphics -C"

To load a hook module “on the fly”, use the new PgPHookRegister() function. No surface or layer data is lost during the installation of a hook module. (Ref# 57091, 72066)

Rotate an image by 90, 180, or 270 degrees. (Ref# 37475, 69235)

Other changes include:

Arcs, Bézier curves, and ellipses
The plotting of these curves is more precise, resulting in smoother lines. (Ref# 58277)
There's a new -a option that enables anti-aliasing on polylines (currently only for diagonal lines of width 1). This anti-aliasing is only for CRT or LCD (video) targets, not printer targets. (Ref# 72316, 72540; Ticket ID 89891)

(Ref# 69322, 69235)

In earlier versions of PhAB, the image-loading library converted all JPEGs to palettized image formats. All 24-bits-per-pixel images without a palette were converted to 8-bits-per-pixel images with a 256-color palette.

As of QNX SDP 6.5.0, the PhAB image library no longer converts JPEGS to palettized images. If you wish to edit a JPEG using PhAB, you must first convert it to a palettized image (such as a GIF) using an external image-editing utility. (Ref# 68393, 68427; Ticket ID 88275)

What's new: Libraries and header files

New functions include:

getpagesizes(), getpagesizes64()
Get the available page sizes (Ref# 71950, 72363)
Get the effective credentials of a UNIX-domain peer (Ref# 69495, 71214)
GLOB_QUOTE is now the default for this function, as specified by POSIX. To revert to the former behavior, specify the POSIX GLOB_NOESCAPE flag.

This function also supports the following flags, which are NetBSD extensions:

(Ref# 74975, 75625)

pthread_mutex_timedlock_monotonic(), pthread_timedjoin_monotonic(), sem_timedwait_monotonic()
These functions are similar to pthread_mutex_timedlock(), pthread_timedjoin(), and sem_timedwait(), but they use CLOCK_MONOTONIC, so the timeout isn't affected by changes to the system time. (Ref# 65150, 71587; Ticket ID 86978)
pthread_mutex_wakeup_np(), pthread_mutexattr_getwakeup_np(), pthread_mutexattr_setwakeup_np()
These functions make it possible for you to unblock threads that are waiting on a mutex. The “np” in these functions' names stands for “non-POSIX.”

In order to make it possible to do this, we've appropriated the list field of iofunc_attr_t. Since it was marked as being reserved, this should be no problem, but if you were using this for your own semantics, then you'll have to make sure that you install your own attribute-locking routines. (Ref# 48722, 71135, 71244)

Other changes include:

We've corrected various bugs in asynchronous messaging (although it remains experimental, is deprecated, and will be removed in a future release).

Note: If your application uses the .a versions of the libasyncmsg library, you must relink it, or else it will hang when used with the new kernel. If your application uses the .so versions of the library, you don't have to relink it.

This function and the callback that it registers now both have an extra argument that points to arbitrary data that you want to pass to the callback. (Ref# 52348, 69784)

Note: You'll need to update and recompile any code that calls this function.

The High Availability Manager now automatically switches to monitoring the new process that daemon() creates, if the original process was a self-attached entity. (Ref# 52131, 71920; Ticket ID 80845)
This function, which is similar to devctl() but uses I/O vectors, is now documented and supported. (Ref# 38751)
RTLD_LAZY is now implemented. For details about it, see “Lazy loading” in the Compiling and Debugging chapter of the QNX Neutrino Programmer's Guide. (Ref# 69098, 69752)
InterruptMask(), InterruptUnmask()
These functions now give an error of ESRCH if the ID parameter isn't something returned by InterruptAttach() or InterruptAttachEvent() respectively, or -1. (Ref# 67694)
ioctl(), ioctl_socket()
We've made ioctl() compatible with other UNIX-based systems by enabling support for embedded pointers. This means that you no longer have to change calls to ioctl() into calls to ioctl_socket() in networking applications, although ioctl_socket() does provide optimized handling for some socket commands.

As a result of this change, ioctl() can now indicate an error of ENOBUFS if there isn't enough memory available to copy the data that the embedded pointers refer to. (Ref# 59556, 71066)

This structure now has a tid_name entry that you can use to specify a name to use for the threads in the pool. For more information, see the entry for thread_pool_create() in the QNX Neutrino Library Reference. (Ref# 73635, 73823)

What's new: Drivers

What's new: Audio device drivers (deva-*)

The audio libraries now support:

For more information, see the Audio Developer's Guide.

What's new: Block-oriented drivers (devb-*)

New drivers:

A pseudo block driver that provides a mapping between an arbitrary file descriptor and the block API, allowing any resource manager to be used to host a disk filesystem.

Other changes:

devb-fdc, devb-ram
Because of updates to io-blk.so, the minimum disk buffer cache is now 512 KB. (Ref# 69116, 69788, 72369)

What's new: Character drivers (devc-*)

The pseudo-tty manager can now support up to 256 ptys, using the naming scheme:

(Ref# 73847, 75536)

What's new: Graphics drivers (devg-*)

The new drivers include:

Graphics driver for Intel GMA HD graphics (Ref# 76277, 77353)

Other changes include:

The memopts option now specifies the name of the configuration file for this driver. This file includes the options that you formerly set with the memopts option, along with a bigendian option that tells the driver that the memory is byte-swapped. (Ref# 70110, 75643)
If you use direct mode with the devg-i830.so driver, images now all appear correctly on the display. (Ref# 61008, 63977)

What's new: Human interface device drivers (devh-*)

The new drivers include:

Driver for Microtouch EXII USB touch devices (Ref# 47435, 75402)

Other changes include:

The following options are new:

If you're using this driver with the USB (devh-usb.so) module, you must specify the igndev option to devh-usb.so, specifying the Egalax vendor and device IDs. (Ref# 74940, 75400)

What's new: Network drivers (devn-*, devnp-*)

The new drivers include:

Driver for Broadcom BCM440x 10/100 Ethernet controllers (Ref# 72462, 76017)
Driver for Intel Tolapai 80579 Gigabit Ethernet controllers (Ref# 72206, 75462)

We've also addressed the following:

The documentation now points out that this driver supports only PCI versions of the Micrel 8841 (1 port) or 8842 (2 port) Ethernet controllers. (Ref# 67333)
devnp-bcm1250.so, devnp-e1000.so, devnp-mpc85xx.so, devnp-rtl8169.so, devnp-speedo.so
These drivers no longer accept the promiscuous option because promiscuous mode is controlled by the stack itself. To enable promiscuous mode, use a BIOCPROMISC ioctl() command; there's currently no way to do this from the command line. (Ref# 71463)

What's new: Documentation

System Analysis Toolkit
We've updated and expanded the System Analysis Toolkit User's Guide. It now includes more information about events and their classes, controlling tracing via tracelogger and TraceEvent(), interpreting the trace data, and lists the data for all events in both fast and wide modes. (Ref# 25473, 29638, 29639, 38156, 44463, 68988)
QNX Neutrino Technotes
We've added the following technotes:

The What Time is It? technote is now part of the Tick, Tock: Understanding the Neutrino Microkernel's Concept of Time chapter of the QNX Neutrino Programmer's Guide. (Ref# 71500)

QNX Neutrino Programmer's Guide
There's now an appendix that explains how QNX Neutrino conforms to POSIX. It also includes a list of non-POSIX functions with POSIX-sounding names. (Ref# 69783)
Building Embedded Systems
The documentation now mentions that if you're creating a buildfile for a MIPS target, you need to create this symbolic link for the runtime linker:
procmgr_symlink ../../proc/boot/libc.so.3 /usr/lib/ldqnx.so.3

instead of this:

procmgr_symlink ../../proc/boot/libc.so.3 /usr/lib/ldqnx.so.2

That is, you should name the link ldqnx.so.3 instead of ldqnx.so.2. (Ref# 71087)

QNX Neutrino User's Guide
The “Video cards” section of the Connecting Hardware chapter contains updated information about configuring multiple displays and about manually configuring your video card. (Ref# 63064)
QNX Neutrino Library Reference
The changes include:
We've added some sample code that you can use to check for stale _PULSE_CODE_COIDDEATH pulses. (Ref# 18264)
We've documented the flags field of the _server_info structure.

If the info argument is NULL, ConnectServerInfo() ignores connections with dead servers and skips to the next coid. If info is non-NULL, the function fills in the _server_info structure; for connections with dead servers, it turns on the _NTO_COF_DEAD bit in the flags field of the structure. (Ref# 18264)

inbe16(), inle16(), inbe32(), inle32()
Note that these macros access the specified port more than once if endian conversion is necessary. This could be a problem on some hardware. (Ref# 73879)
This function gives an error of EBUSY when you're trying to name a thread other than the calling thread, and another program already has write access to the process's entry in the /proc filesystem. For more information, see the entry for pthread_setname_np() in the QNX Neutrino Library Reference. (Ref# 73930)
spawn(), spawnp()
We've added more details about working with the fd_count and fd_map arguments to set up the file descriptors in the child process; see “Mapping file descriptors” in the entry for spawn() in the QNX Neutrino Library Reference. (Ref# 25715, 69655)
You can use this function to shut down the system, customizing the function by providing your own callouts:
  • shutdown_classify()
  • shutdown_display()
  • shutdown_done()
  • shutdown_error()
  • shutdown_process()
  • shutdown_progress()
  • shutdown_prompt()

(as the shutdown and phshutdown utilities do) to override the default behavior. (Ref# 67819)

trace_func_enter(), trace_func_exit(), trace_here(), trace_logb(), trace_logbc(), trace_logf(), trace_logi(), trace_nlogf(), trace_vnlogf()
The QNX Neutrino Library Reference now includes entries for these functions, which provide convenient ways for you to insert trace events into the data collected by the instrumented kernel. (Ref# 69991)

See also the “What's New” appendix in the QNX Neutrino Library Reference.

Utilities Reference
The changes include:
The entry in the Utilities Reference now has the correct instructions for invoking this command. (Ref# 68568)
We've documented the phys_align attribute, which you can use to specify the physical alignment of objects. This attribute overrides the new big_pages attribute (see What's new: Compiler, tools, and utilities). (Ref# 52435, 71815)
We've described the generic and architecture-specific options for startup programs. (Ref# 74069)

Note: Individual startup programs can override these options and may support additional board-specific options. The order of precedence is as follows:
  1. board-specific options
  2. architecture-specific options
  3. generic options

See also the “What's New” appendix in the Utilities Reference.

What's new: I/O devices

What's new: Security

This release addresses the following security concerns:

Using the VMware image of a QNX Neutrino runtime system

We provide a VMware image of a QNX Neutrino runtime system in target/QNX_Eval_RT.zip on the installation DVD; it's also available in the Download area of our website.

To install this image, do the following:

  1. Extract the VMware target from the DVD. For example, on Windows, open a Windows Explorer window, double-click on the target\QNX_Eval_RT.zip file, and then drag the QNX_Eval_RT folder to some location on your hard drive (e.g. My Documents).
  2. To launch, either:
  3. When VMware Player displays a dialog saying that the virtual machine was moved, select Create and click OK.

If you find problems with any virtualization environment, please post your findings in one of the forums on our Foundry27 community website.

What's new in the QNX Momentics Tool Suite?

The changes to the QNX Momentics Tool Suite include the following:

For more details, see the following sections:

What's new: Compiler, tools, and utilities

The QNX Momentics Tool Suite 6.5.0 includes the following versions of the compiler and tools:

We've also implemented lazy binding, RTLD_LAZY, and lazy loading; For more information, see the Compiling and Debugging chapter of the QNX Neutrino Programmer's Guide. (Ref# 69098, 69752)

New utilities include:

This utility converts standard CLDR (Common Locale Data Repository) language collation (or sort order) tables into a format usable by the libqdb_cldr.so DLL. For more information, see the entry for mkcldr in the Utilities Reference, as well as Customizing language sort orders for libqdb_cldr.so in the QNX Neutrino Technotes.
A script that QNX Technical Support might ask you to use to gather system information for troubleshooting purposes (Ref# 69320, 75634)
Display the length of time that the system has been running (Ref# 76091, 76240)

Other changes include:

By default, applypatch now installs the host-side files only for the current host OS. There's a new -H option that makes applypatch install the host-side files for all host OSs. (Ref# 69926, 72362)
We've renamed the -n option to be -u, to be consistent with other platforms. The -n option is still recognized. (Ref# 57828, 74887; Ticket ID 83753)
This utility now supports the POSIX -b and -n options. (Ref# 71737, 71738)
If you start it from the command line on a self-hosted QNX Neutrino system, gdb sets LD_BIND_NOW to 1 to force the loading of all lazy-load dependencies. (Ref# 75695)
In order to conform to POSIX, we've changed the -n option so that it always specifies the number of lines to copy. The -c option now takes an argument that specifies the number of bytes to copy. Note that the -c and -l options are QNX Neutrino extensions. (Ref# 65661, 65662)
We've brought in some bug fixes from NetBSD:

(Ref# 72014)

We now ship only the POSIX version of this utility, which creates a hard link instead of a symbolic one. (Ref# 75830, 75831)
mkefs, mketfs
These utilities now support a mountperms attribute that you can use in a buildfile to specify the permissions to use for mountpoints. The default permissions are 0777 for mkefs, and 0755 for mketfs. (Ref# 64471, 71487)
This utility supports the following new attributes:

You can specify these attributes in the buildfile or in the bootfile. (Ref 71850, 71961)

We've updated the bootfiles for ARM targets to include the big_pages and pagesizes attributes. (Ref# 71962)

Other changes include:

This utility has a new -n option that you can use to adjust the debugged program's priority to be lower than pdebug's. Doing this can keep pdebug from becoming unresponsive if the debugged process misbehaves (e.g. looping in a tight loop taking lots of CPU time).

The usage message and documentation now include the following options:

(“One”) Exit pdebug after the debugging session is done.
Run pdebug as a foreground process.

(Ref# 69794, 69803)

By default, pdebug sets LD_BIND_NOW to 1 to force the loading of all lazy-load dependencies. You can prevent pdebug from setting LD_BIND_NOW by specifying the -l (“el”) option. (Ref# 75695)

As a QNX Neutrino extension, the time argument can be a floating point number, so you can specify fractions of seconds. For POSIX conformance, time must be an integer. (Ref# 71599, 73908)
unzip, unzip
We've updated zip to Info-Zip version 3.0, and unzip to version 6.0. These versions provide large file support. (Ref# 70772, 76915; Ticket ID 89505)

What's new: Integrated Development Environment

The QNX Momentics Tool Suite 6.5.0 includes version 4.7 of the IDE, which includes the following new features:

The website for updates and maintenance releases — which you access via Help-->Check for Updates in the IDE — is https://www.qnx.com/account/updates/ide/4.7/.

For more information about changes to the IDE, see the What's New in the IDE appendix of the IDE User's Guide.

Debugging information for shipped binaries

We generate the QNX SDP binaries with debugging information (-g) and map files. With few exceptions, all binaries are available with debugging information, but this data as well as the .ident information are stripped and stored in a separate binaryName.sym file. These files are linked together, so gdb understands where to find the symbol data.

There's now no need for a separate debug version of all the binaries. There's a separate tar file containing all the .sym files that will untarred alongside each binary. This file is available in the Download area of our website, as well as in the debugging_info directory on the QNX SDP DVD.

What it means to you:

These *-buildid.sym files are in CPU-specific tar files. The usage of these tar files is straightforward. Suppose you want to debug the ls command for x86. You could just add the entire set of debug files to your target (you need to be root, of course):

  1. Get the target-x86-debug-date.tgz file.
  2. cd $QNX_TARGET
  3. tar -zxf path/target-x86-debug-date.tgz

Then ntox86-gdb $QNX_TARGET/bin/ls would load the debugging symbols from the .sym file automatically. Since this is the full debugging information, you can point gdb at the location of source for ls.

You don't have to extract the entire tar file. In fact all that matters is that the .sym file be in the same directory as the binary. So you could simply copy $QNX_TARGET/x86/bin/ls and the x86/bin/ls-*.sym file (from the debug tar file) to your current directory, and then run gdb there.

In order to get a list of the source files used to build a binary (e.g. to determine the associated licensing), use the .sym file instead of the binary. So continuing with the example above, to get a list of the source files used in building ls, type:

use -s $QNX_TARGET/x86/bin/ls-*.sym

Discontinued items

The following items will be removed from the next release of QNX SDP and will become part of a separate product:

Note: The Web Browser Engine in 6.5.0 doesn't include any ARMv7 binaries.

We've deprecated the CMU version of SNMP that's currently included in QNX SDP, and we'll remove it from the next release. We recommend that you use NuDesign's SNMP instead. For more information, see the Partners area of our website. (Ref# 70524)

Starting with this release, graphics drivers for chipsets that have been out of production for five years will be deprecated. Where possible, the source code for these graphics drivers will be posted on Foundry27.

The following graphics drivers have been deprecated:

Experimental items

Caution: Experimental software is primarily provided for customers and the community to try out, and perhaps to get a glimpse of what might be in store for the future.

The experimental items in QNX SDP 6.5.0 are:

Known issues

QNX SDP 6.5.0 contains known issues in these areas:

Note: We're actively investigating all known issues.

Known issues: Installing and uninstalling

Known issues: Kernel

Some multiprocessor systems, such as the Power Book E and the ARM Cortex-A9 MPCORE, have an interrupt controller on each processor, but QNX Neutrino currently assumes there's only one controller. Unmasking an interrupt on one processor may leave it masked on other processors. (Ref# 60301)

Workaround: Bind all threads that mask and unmask interrupts so that the threads run only on CPU 0.

ARMv7 Cortex Processors
At the time of release, the feature to generate NEON instructions wasn't tested on Cortex-A9 because there are currently no Cortex-A9 implementations with a Neon unit. As a result, the feature is available on an “as is” basis.

Known issues: Libraries and header files

Unnamed semaphores aren't inherited across a fork() (Ref# 59947, 73710)
This library causes some problems on x86 targets if it's compiled with gcc 4 with optimization above -O0. To avoid these problems, we've compiled the DLL with -O0 optimization for x86. (Ref# 55883)
This library is a Neutrino interface to version 1.1 of the Expat XML Parser, but it isn't documented. For information about this library, see <xmlparse.h> and <xmltok.h> in $QNX_TARGET/usr/include. (Ref# 56140)
In the current implementation, posix_spawn() can indicate an error of EMSGSIZE. This is most likely the result of attempting to operate on too many file descriptors in the posix_spawn_file_actions_t object passed to posix_spawn() or posix_spawnp() and/or an overly large environment variable list (either through inheritance by passing NULL for the envp parameter to posix_spawn() or posix_spawnp() or by explicitly providing an overly large envp parameter). (Ref# 75606)

Workaround: Reduce the number and size of the environment variables and/or number of file descriptors being manipulated with the posix_spawn_file_actions_t object.

shm_ctl(), shm_ctl_special()
If an error occurs, these functions set errno to ENOSYS (not EINVAL as documented). They should provide better diagnostics. (Ref# 26440)
This function doesn't check the priority range when PTHREAD_EXPLICIT_SCHED is set. For example, if you use the on command while logged in as a non-root user, and you specify a priority greater than 64, on still executes the command but at the priority of the calling shell. It should give an error saying you don't have permission to create at that priority. (Ref# 28763)
Time zones
QNX Neutrino uses a nonstandard method of defining time zones that's difficult to keep up to date. We plan to replace it in a later release. (Ref# 44425)

Known issues: Filesystems

On ARM platforms, you can't use an io-fs-media share to store a directory structure with more than 16 MB of data. (Ref# 56601)
If you send a SIGTERM or SIGKILL signal to a devb-* driver, chkfsys might subsequently find errors on the filesystem. (Ref# 48741, 48764, 48765)
If you try to delete a linked file or directory in a Linux Ext2 filesystem, you get a “Corrupted file system detected” error. (Ref# 50264)
The io-blk manager lets you mount a filesystem in a file. To do this, you basically create a normal file on a disk, and then format it (via dinit, mkqnx6fs, mkdosfs, etc.), as a filesystem. You can then run a command, such as:
mount -tqnx4 /home/myfs.img /fs/test

and you'll get a mountpoint called /fs/test, which is the size of the file and is formatted as a QNX 4 filesystem.

If you used fs-qnx6.so as the real filesystem on the hardware, and then created a QNX 4 or DOS filesystem inside a file residing on the Power-Safe filesystem, the host filesystem formerly could become damaged by the modifications to the hosted filesystem. We've fixed that, but the host filesystem might not be able to confer full power-loss safety to the (by design) not power-loss-safe QNX 4 or DOS filesystem. (Ref# 74580)

If you specify a flag such as noatime on a block filesystem, and then you remount the filesystem (mount -u), the flag is ignored. The absence of the flag is interpreted as your asking for access time updates to be turned on. There's no way for the code in io-blk to determine if you wanted to use the default, and therefore didn't specify anything, or really did want access time updates to be turned on, and therefore didn't specify anything. (Ref# 77323)

Workaround: Specify the flags again using the -o option for the mount command. For example:

mount -u -o noatime ...

Known issues: Startup

Known issues: Adaptive partitioning

Known issues: Booting

Known issues: BSPs and DDKs

Known issues: Compiler, tools, and utilities

ksh, pipe
There's a problem with interactions between pipe and ksh on SH targets. If you use multiple pipes in a command line under ksh, all output can be lost. For example:
# uname -a
QNX renesas_sh7785 6.5.0 2008/09/26-04:27:12EDT SDK_7785 shle
# uname -a | grep renesas
QNX renesas_sh7785 6.5.0 2008/09/26-04:27:12EDT SDK_7785 shle
# uname -a | grep shle
QNX renesas_sh7785 6.5.0 2008/09/26-04:27:12EDT SDK_7785 shle
# uname -a | grep renesas | grep shle

(Ref# 62242)

If the first page of a memory-mapped object is written to, pidin might display /dev/zero instead of the object's name. (Ref# 43050)
When a kernel call fails, the instrumentation records the errno value. However, if you use traceprinter on the .kev file in a cross-endian environment (e.g. the .kev file was generated on big-endian, and you're running traceprinter on little), the errno value that gets printed isn't swapped before being displayed. For example, an EFAULT is displayed as 0xe0000000 rather than 0xe. (Ref# 76429)

Known issues: Device drivers

Audio device drivers (deva-*)

Block-oriented drivers (devb-*)

Reading DVD-RAM causes devb-adpu320 to become blocked on a CONDVAR. (Ref# 19772)
You can't restart this driver on IBM PPC405 boards. (Ref# 16018)

Graphics drivers (devg-*)

Human interface device drivers (devh-*)

Network drivers (devn-*, devnp-*)

This driver doesn't support the 1000 MB/s interface of the Linksys Gigabit USB Adapter (model no. USB1000). (Ref# 38115)

Workaround: Force the driver to use speed and duplex settings that it supports (10 and 100 Mbit/s).

The devnp-axe.so USB-Ethernet dongle sometimes drops packets when used on slow systems or with UHCI. (Ref# 62088)

Workaround: If you encounter problems with this driver, use the io-net driver devn-asix.so instead.

The io-pkt driver for the Intel i82544 doesn't support dual-port cards (did=0x1010). (Ref# 44299)

USB drivers (devu-*)

Known issues: IDE

The IDE contains the following known issues:

See also the list of host-specific issues, later in these notes.

Known issues: General

Known issues: Application Profiler perspective

Known issues: System Profiler perspective

Known issues: Memory Analysis perspective

Known issues: System Information perspective

Known issues: System Builder perspective

Known issues: C/C++ development

Known issues: Team/CVS

Known issues: Debugging

Known issues: Documentation

Known issues: Instant Device Activation

Known issues: I/O devices


Known issues: Multimedia

Multimedia TDK 1.0.1
QNX SDP 6.4.1 and later don't support Multimedia v1.x. Applications that depend on Multimedia v1.x will no longer resolve symbols or execute under 6.4 or later. For multimedia support, you need to install the QNX Aviage Multimedia Suite. (Ref# 55967)

Known issues: Networking

When using the m_pkthdr_csum_data member in network driver code, make sure that you use only the bottom 16 bits. The top 16 bits may contain undefined data. (Ref# 44622)
The commands:

ifconfig iface_name up
ifconfig iface_name up

don't work individually for WiFi drivers. (Ref# 61246)

Workaround: Combine the commands:

ifconfig iface_name up scan

fs-nfs2, fs-nfs3
The stack might send zero-length mbufs to a driver for transmission. (Ref# 44621)

Workaround: Drivers must accommodate for this by checking the length of the data in the mbuf and ignoring the mbuf if the length is zero.

nfsd lets you access files only up to 16 subdirectory levels deep within the directory exported in the /etc/exports file. Deeper directory levels and files aren't accessible. (Ref# 40104)
NTP clients might not stay synchronized with the server. Our investigation has revealed that this happens because ntpd uses floating-point calculations in a signal handler (SIGIO) when processing incoming (and other asynchronous activity) packets or I/O. This causes corruption in the floating-point context in the emulator, which causes problems in subsequent calculations. (Ref# 74509)
TCP/IP (part of io-pkt)

Known issues: Graphics

Advanced Graphics

An internal structure exchanged between libimg and the image codecs changed after we released version 2.0 of the Advanced Graphics TDK. Applications compiled and linked statically against the earlier versions of imglib.a might not function properly, especially while decoding JPEG images. (Ref# 48003, 56557)

Workaround: Relink the applications against the newer version of imglib.a.

The Advanced Graphics libffb library doesn't support blitting to a PAL8 surface from a non-PAL8 surface. Therefore, Pg_IMAGE_PALETTE_BYTE offscreen contexts can be blitted to and from only offscreen contexts of the same type. (Ref# 20391)

Changing modes or stopping and then restarting graphics
When changing modes or stopping and then restarting graphics using devg-i830.so, the machine might enter a bad state and power down. (Ref# 74803)

Workaround: Do the following:

  1. Boot into safe mode (during the boot process, press Space, press F1 for Safe Mode, and then press F3 so that Photon doesn't start).
  2. Edit the file /etc/system/config/display.conf and set drivername=i830, set resolution values for xres and yres, and then set a refresh rate value for refresh.

    For more information about display.conf, see io-display in the Utilities Reference.

  3. slay and then restart io-display:
    slay io-display

    and then at the prompt type:

    io-display -dvid=0x8086,did=MypciDeviceID

    where MypciDeviceID is the PCI device ID for your specific device.

  4. Start Photon (use the ph script).

Photon microGUI

Photon isn't supported on ARMv7 targets.
The Using the Photon microGUI chapter of the Neutrino User's Guide and the entry for pwmopts in the Utilities Reference refer to wframe_update.so, but the name is actually wframe_updated.so (with a second “d”). (Ref# 65310)
Arcs, Bézier curves, and ellipses
The default line joint is a miter, which doesn't produce good results for these curves, and — contrary to what the documentation says — the setting of the line joint is ignored if you use stroked arcs or stroked ellipses. Using PgSetStrokeJoin(Pg_BEVEL_JOIN) may give smoother results once this issue is resolved. (Ref# 58185)
Dual-head displays
On systems with a dual-head display and screens set up to display different portions of the logical desktop, some convenience functions — such as PtFileSelection() and PtNotice() — are always constrained to the first screen. (Ref# 59614)
We don't currently ship phs-to-pcl for PPCBE; it will be provided in a forthcoming release. (Ref# 61378)
Starting Photon
When you start Photon, you might see a “Cannot attach mouse input report (error code2)” message on the console. It's a benign message that you can ignore. (Ref# 29662)
PhAB for Windows

Windows hosts

Coexistence on Windows 7
Although 6.5.0 is the first version of QNX SDP that's supported on Windows 7, you should be able to install and use earlier versions. However, if you try to change the current version of the tools (via the QWinCfg utility or the Configuration menu item), QWinCfg will display a dialog that says you can't save any changes because you aren't an administrator. This is because of changes to the User Access Control (UAC) system on Windows 7. (Ref# 69243)

Workaround: Do the following:

  1. Start a command prompt.
  2. Run the ksh command.
  3. Type qconfig to get the installation name of the required configuration.
  4. Run the following command, specifying the installation name:

    eval `qconfig -n "Installation_name" -e`

    For example, to switch to 6.3.2, run this command:

    eval `qconfig -n "QNX Momentics Development Suite 6.3.2" -e`
The following issues apply to the Windows-hosted version of the IDE:
Vista and Phindows or PhAB
On Vista, Phindows and PhAB seem to interfere with the gadget toolbar; the sidebar flickers and appears and disappears very rapidly and often, slowing down the system. (Ref# 62277)

Workaround: This may be related to Phindows and PhAB's use of Direct3D double buffering, which is redundant when the Vista Aero compositing is enabled. To disable double buffering:

On Windows, the QNX-provided echo.exe interprets the Windows \ separator as an escape character. As a result, environment variable settings won't work if you use \ as a path separator; use / instead. (Ref# 19924)
Microsoft Visual Studio also uses the MAKEFLAGS environment variable, but in a much different way than QNX Neutrino does. The result is that Microsoft Visual Studio no longer works after you've installed QNX Momentics.

Workaround: If you want to work with Microsoft Visual Studio (MSVS) after installing QNX Momentics on the same system, do the following:

  1. Open a command window and run cmd.
  2. Type set.
  3. Find the value for MAKEFLAGS and save it.
  4. Type set MAKEFLAGS.
  5. Do your MSVS work.
  6. To work with QNX Momentics again, type:

    set MAKEFLAGS=saved_makeflags_value

sh, ksh
Because of the way that the MSYS versions of the shell manipulate the environment variable, PATH doesn't appear to include $QNX_HOST/usr/bin, but it does. (Ref# 59412)
User Account Control (UAC)
Windows Vista includes an account policy, called User Account Control (UAC), that impacts various administrative features, such as being able to create and store files in a temporary directory (tmp). This directory is used by various applications, such as CVS and the split command, and various Photon applications. To successfully run these applications on a computer running Windows Vista, you must have administrator privileges and disable UAC. (Ref# 44027)

Workaround: To disable UAC on your Windows Vista configuration:

  1. Launch MSCONFIG by from the Run menu. (When you click on the launch button — the one with the windows logo commonly in the bottom left corner — the Run menu is an editable text bar with the string Start Search. Type msconfig and then press Enter.)
  2. Click on the Tools tab. Scroll down until you find Disable UAC, and then click that line.
  3. Press the Launch button.
  4. A cmd window will open. When the command is done, you can close the window.
  5. Close msconfig, and then restart your computer.

You can reenable User Access Control by selecting the Enable UAC line and then clicking the Launch button.

Caution: Disabling UAC bypasses some of Vista's security features.

For Windows XP, the location that the BSP file for the IDE installs into is $QNX_CONFIGURATION/qconfig_directory, and it is write-protected for a default user. Consequently, subsequent updates to BSPs aren't permitted in this location because of permission errors under Windows Vista configurations if the user doesn't have administrative permissions. (Ref# 44668)

Workaround: Modify your user permissions. For instructions about changing these permissions, see the steps in the workaround for the problem (Ref# 44027) above.

QNX utilities
The Windows installation includes various executables that have the same name as some QNX utilities, such as find, sort, and split. By default, Windows places the path to the Windows executables at the beginning of the Windows PATH environment variable, and the QNX executables appear afterward. This means that when you run these utilities from the command line, instead of using the QNX version, the PATH variable uses the Windows version. (Ref# 44457)

Workaround: If you want to use the QNX utilities for find, sort, and split from a command prompt or shell prompt, specify a fully qualified path to any of the QNX executables.


Linux hosts

The installers can't update the Gnome menu on some distributions of Linux. (Ref# 48770)

List of fixes

The problems fixed in QNX SDP 6.5.0 include the following:

Software fixes

Change Ref#
We've fixed certain cases in the IDE where the common.mk file for a QNX Project was corrupted when the properties were saved. (Ticket ID 67456) 75694
When thread dies during debugging, the IDE's debugger no longer shows it in the thread list as a duplicate of the previous thread; it's now removed from the list. (Ticket ID 101323) 75273
In the IDE, if you profile a process where multiple threads call the same function, the samples are now assigned to the correct threads. 75186
GLOB_QUOTE is now the default for glob(), as per POSIX. To revert to the former behavior, specify the POSIX GLOB_NOESCAPE flag. 74975
Graphics support for the Intel G35 chipset has been added to devg-i830.so. 74926
Some systems have been found to lock up when using the vsync interrupt for devg-radeon.so. The default behavior of the driver has been changed to poll for vsync.(This was the behavior prior to 6.4.0) A new driver option has been added to allow a user to try to use the vsync interrupt; set use_irq=1 in radeon.conf. 74853
Hardware cursor support has been fixed for the Dell Latitude E5x00. The devg-i830.so driver also restores settings correctly on exit to properly return to the previous graphics mode. 74817
We've updated to OpenSSL version 0.9.8m, which addresses an issue with the SSL 3.0+ and TLS 1.0+ protocols that made them vulnerable to a set of related attacks that allow a man-in-the-middle (MITM) operating at or below the TCP layer to inject a chosen plaintext prefix into the encrypted data stream, often without detection by either end of the connection. (VU#120154) 74597
Breakpoints on constructors and some other C++ methods can cause the IDE's debugger to insert multiple breakpoints per location. These breakpoints are now displayed correctly in the Breakpoints view. (Ticket ID 101196) 74430
If a low priority thread (Thread A) holds a mutex, and thread A is SEND/RECEIVE blocked on a thread (Thread B), while a high priority thread (Thread C) is waiting on the mutex from Thread A, the priority (from Thread C) is now propagated to both Thread A AND Thread B (note: when the priority is propagated to Thread B, both the current priority and actual priority of the thread change). 74248
We've resolved a problem that existed with the vmm_map_xfer() function special-casing xfer_diff()/xfer_prp() based only on the first iov. A multi-iov transfer (where some iovs specify normal user addresses but others specify global addresses) now work correctly. An adjustment was made to the iov base on on individual basis, and the cpu_vmm_fault() handler now checks whether xfer_diff() applies to the faulting address. 73614
We're corrected a problem with the IDE's code coverage that caused an internal error. 73332
The io-graphics command no longer faults if you set up your system to not display the cursor by adding cursor=none to the photon section of display.conf. 73285
We've corrected a problem that existed when there was a pending pthread_mutex_timedlock(), and the mutex owner no longer existed. The cleanup code entered into an infinite loop because it attempted to clear out all of the blocked entries, but instead did nothing for timed locks. We now ensure that the user code is forced out with an EOWNERDEAD error (meaning that the owner of the lock died while holding it). 73133
The io-pkt networking stack no longer crashes when you create at least three instances of pppd and then terminate them in the order in which you created them. (Case# 00100180) 73053
The floating point register F0 no longer gets corrupted on multiprocessor MIPS systems. 72861
The socklen_t data type is now unsigned to conform with common practice. 72839
You can now successfully run the devg-poulsbo.so driver with a resolution of 640x480. 72768
We corrected a function, which the kernel uses internally to get information about a particular virtual address, so that it works correctly if the address space used in the request is something other than the active address space. 72699
We've addressed a denial of service vulnerability affecting any system using ntpd from xntp2 (1989), such as high CPU usage, excessive disk use due to logging, and significantly increased network traffic. (CERT VU#568372, CVE-2009-3563) 72603
Partial corruption of message data no longer occurs on the PowerPC 440EP. The corruption would take the form of some message data being zeroed. This was as a result of uninitialized memory not being completely zeroed before the message pass was performed; upon first access of the memory by the process, the data would be zeroed. The full destination message area is now fully zeroed and initialized before the message pass is performed. (Ticket ID 90399) 72554
The kernel no longer crashes while flashing targets. The error was in the interrupt code generated at run time on the SH family of processors, which led to an incorrect jump if all interrupt ID routines indicated that they didn't own the interrupt; we've corrected the generated interrupt code. 72386
The io-graphics subsystem now has an -a option that enables anti-aliasing on polylines for displays (CRT/LCD).It currently applies only to diagonal lines of width 1. (Ticket ID 89891) 72316
In the IDE, if you copy data from the Application Profiler's Execution Time view to a clipboard, the data for fields that contain both data and an image is now copied correctly. 72249
An exception at the wrong time on PowerPC SMP systems no longer causes messages to be truncated. (Ticket ID 88273) 71289
We've addressed a race condition in pathmgr_open(), so that a double free() can no longer occur on an open_entry(). 71287
The IDE's Problems view no longer contains stale or inaccurate information when a project contains files that are linked to files in another project. 71277
We've fixed the SERCTL devctl() to allow multi-line toggles. 71275
In-kernel emulation of floating point load/store operations no longer crashes the kernel when multiple load/store instructions are present and cross a page boundary, and the next page's pagetable attributes are invalid. Only the current page is now assumed to be valid; upon reaching a page boundary, the emulation is completed, which means that the next page is validated before the next instruction is emulated. 71065
We've fixed the dial-on-demand feature so that pppd is notified to begin the connection procedure when a packet is sent on the interface and to clean up on disconnection. If the serial device resource manager returns 0 for a disconnected link, we now notify pppd so that it can see the link disconnection even if it isn't the session leader for the controlling terminal (i.e. it was started with the nodetach option). 71018
The io-display manager no longer constantly creates and destroys threads when more than two clients are connected. 70956
The io-display manager no longer leaks memory when more than two applications are running simultaneously. 70898
The following integer types are now defined in <sys/types.h> for System V compatibility if Unix extensions are enabled (i.e. if __EXT_UNIX_MISC is defined):

typedef unsigned short ushort
typedef unsigned int uint;
typedef unsigned long ulong;

Alpha map processing for rectangles is now processed faster on "non-linear" access GPUs. 70526
The IDE's System Builder now uses relative paths (or variables) instead of absolute paths where possible in the search paths. (Ticket ID 89203) 70401
If you export the bin and band events from the IDE's Memory Analysis, the data is now sorted by event ID. (Ticket ID 89309) 70333
You can find the cpu_mdriver.c and mdriver.c files (used for Instant Device Activation) in $QNX_TARGET/usr/src/archives/qnx/mdriver-base.zip. 70278
The wave utility now correctly checks the value returned by snd_pcm_plugin_set_disable(). We've also incorporated the updated source code in the Audio Developer's Guide. 70219
The devg-flat.so driver now has a configuration file. One of the options in it lets you indicate that the memory is byte-swapped, so that the driver will run properly on a big-endian system. 70110
The devg-flat.so driver is now functional in 6.5.0 (Ticket ID 88856) 69792
You can now set the tracing mode to fast or wide for specific events in the _NTO_TRACE_THREAD class. You can also do this for events in the _NTO_TRACE_PROCESS and _NTO_TRACE_VTHREAD classes, but there's currently no difference between the data for fast and wide mode for these classes. 69613
The correct Pg_LAYER_FORMAT_* value is now returned in the PgLayerCaps_t format member. 69322
In the IDE, you can now disable a builder for a QNX Project. 69291
In the IDE's System Profiler, it is now possible to have two or more editors operating independently of each other based on the filters selection. 69249
1. OTF (OpenType Font) types are supported now. 2. Users should discontinue using T2K-fm and T2K-cache libraries as they have been merged into T2K library. 3. T2K_BorderFilerParams structure has changed. The R,G,B members got renamed into Red, Green, Blue respectively. 69112
You can now set the source viewport of a layer (for panning/scrolling) in devg-gma9xx.so. 69038
PpPrintWidget() no longer faults when reading a file into a stack buffer. (Ticket ID 88599) 68995
Threads are no longer left in the STOPPED state when a process dumps core. 68948
The etfsctl utility can now read raw partitions at a specified offset. 68911
The statvfs() function now reports the correct number of free files on an ETFS when long filenames are used. 68898
The make command on Windows XP now correctly parses the MAKEFLAGS. 68853
We've corrected the options in the usage message for devi-microtouch. 68795
Improvements have been made to gf_draw_finish() and gf_draw_flush() with respect to drivers that don't require layer_flushrect() updates. If your application is linked statically against libgf.a, we strongly recommend that you relink it. 68760
The etfsctl utility can now write a file into a raw etfs partition at a specified offset. 68671
Line joins are now supported in Photon's dashed thick lines. Previously the joins were ignored, even if they were set. If you have erroneously set the line join with dashed thick lines, and had not intend to, you will have to change your code. 68641
The /var/chroot/sshd directory is now correctly owned by root:root with permissions of 0755. 68628

Photon applications no longer SIGSEGV if the font manager isn't running. 68517
If the priority of every server thread in devf-generic is boosted because of a SEND-blocked client, the original priorities are now correctly restored upon receipt of the client's message; as a result, low-priority threads no longer perform long, time-consuming tasks at a high priority. (Ticket ID 88359) 68497
The io-pkt manager no longer becomes reply-blocked when you use pppd with a serial port. 68456
If both ppc variants (spe and regular) are created in the same project and at least of them enabled both would be build. 68221

Issues have been found with the version of OpenSSH that ships with NetBSD 3.x, NetBSD 4.x, and NetBSD-current. The two known security issues include X11 session hijacking (CVE-2008-1483) and a bypass of the ForceCommand directive (CVE-2008-1657). We now use OpenSSH 5.2, which contains the appropriate fixes. 62889
We've suppressed an informational message concerning truncation that appears when you start an ETFS. Since this message doesn't indicate an unrecoverable error, it's now displayed only if you start the filesystem with a verbosity of one or greater. (Ticket ID 84762) 61433
We've fixed a race condition between kernel no-op processing and pthread_cancel(). 59261
When you're unmapping memory, a mutex is no longer identified as an item to destroy if the process has another mapping to the same page. (Ticket ID 82614) 55518
The IDE's Expression view now lets you format variables as hexadecimal and other formats. 52773
The High Availability Manager now automatically switches to monitoring the new process that daemon() creates, if the original process was a self-attached entity. (Ticket ID 80845) 52131
In the IDE, the Memory view as ASCII now supports 64 and 128 columns. 46977

The serial (devc-*) drivers now check to make sure that memory allocations were successful. 24309
Palette matching has improved. (Ticket ID 68240) 24289

Documentation fixes

Change Ref#
The documentation for ThreadCreate() now says that you can use __tls() to get a pointer to thread local storage. 77345
An error of EINVAL from clock_settime() could mean that tv_sec is -1. We've updated the entry for clock_settime() in the QNX Neutrino Library Reference. 76708
A VLAN tag is a 12-bit number, not a 16-bit number; we've corrected the documentation for ifconfig. 76665

The documentation for mq_open() and mq_unlink() now mentions that these functions indicate an error of ENOSYS if neither mq nor mqueue is running. 74946
The documentation for pci now warns that this utility is intended for debugging purposes; running it on an active system may cause some devices to hang. 74893
For regexec(), we've corrected the naming of the members from rm_sp and rm_ep to be rm_so and rm_eo respectively. 74884
The documentation for fs-dos.so now says that the default value of the fat option is nonrmv. 74682
The QNX Neutrino User's Guide and the documentation for mount now include examples of how to remount a filesystem as read-only and read-write. 74680
The documentation for usbd_string() now points out that the returned string includes a terminating null character, and that the function returns NULL if the string table doesn't exist. 74659
We've added an entry for devb-mvSata to the Utilities Reference. 74531
If you specify SHMCTL_PHYS in the flags to shm_ctl() or shm_ctl_special(), then paddr and size must be even multiples of the page size (sysconf(_SC_PAGE_SIZE)). 74502
The alignment argument to posix_memalign() must be a multiple of size( void * ) that's also a power of 2; we've corrected the documentation. 74482
The gf-calib option for specifying the layer index is -l (“el”), not -I. We've corrected the documentation. 74316
The snd_pcm_plugin_read(), snd_pcm_plugin_write(), and snd_pcm_read() functions indicate an error of EIO if the channel isn't in the prepared or running state. 74217
All x86 startups support a -B option, which you can use (if the BIOS is buggy) to prevent the startup from using the ACPI table to determine the number of logical CPUs. We've updated the entries for the startups in the Utilities Reference. 74159
We've corrected the spelling and description of SHMCTL_HIGHUSAGE in the entries for shm_ctl() and shm_ctl_special() in the QNX Neutrino Library Reference. 74070
The versions of zip and unzip that we ship are for x86 targets only. We don't ship them for Linux hosts. 73951
We've corrected the documentation for wordexp(): word expansion isn't implemented, so this function returns WRDE_NOSYS; it doesn't set errno. 73799
The QNX Neutrino User's Guide now says that devc-con-hid supports USB keyboards in text mode. 73776
The entry for procnto* in the Utilities Reference now describes procnto-booke-smp. 73236
The Composition Manager Developer's Guide now directs you to the Graphics project on Foundry27 for the demonstration programs and tutorials. 73195
In the IDE, for the Memory Analysis Tool, the Trace Details and Statistics views were removed as well as the corresponding documentation. The functionality that these views provided is now available by using the filters on the Memory Events view. In addition, although you can continue to use libmalloc_g.so, use librcheck.so to obtain memory statistics. 73187
The entries for send(), sendmsg(), and sendto() in the QNX Neutrino Library Reference now describe the MSG_NOSIGNAL flag. 73177
We've corrected the description of MALLOC_MMAP_NOZERO. If this environment variable is nonzero, then when malloc() needs to expand the heap, it specifies the MAP_NOINIT flag when it calls mmap(); if the physical memory being mapped was previously unmapped with UNMAP_INIT_OPTIONAL, then the POSIX requirement that the memory be zeroed is relaxed. This environment variable has been supported on all architectures since QNX Neutrino 6.3.2. 72765
We've corrected the documentation for PhCancelDrag(); this function returns a non-negative number (&ge; 0), not a positive number (&gt; 0), to indicate success. 72724
The Utilities Reference now includes an entry for startup-bios-32, the startup for PC-compatible systems with a BIOS, using 32-bit physical addresses. 72656

The documentation for mq_open() and sem_open() now correctly describe how these functions handle the name argument. 71752
The documentation for mkdir and mkdir() now points out that not all filesystems (such as /dev/shmem, which isn't really a filesystem) support the creation of directories. 71638
The default value for the MALLOC_ARENA_CACHE_MAXBLK environment variable is 12, not 8; we've corrected the documentation for malloc(). 71606
The devnp-bcm1250.so, devnp-e1000.so, devnp-mpc85xx.so, devnp-rtl8169.so, and devnp-speedo.so no longer accept the promiscuous option because promiscuous mode is controlled by the stack itself. To enable promiscuous mode, use a BIOCPROMISC ioctl() command; there's currently no way to do this from the command line. 71463
POSIX doesn't define any errors for the sleep() functions. 71356
The documentation for sopen() now says that this function gives an error of EEXIST if the O_CREAT and O_EXCL flags are set, and the named file exists. 71265
The SQE (Squelch Test Errors) counter isn't applicable to devnp-e1000.so and devnp-i82544.so, so they use it to track the number of internal Rx FIFO overruns. For more information, see the Utilities Reference. 71191
The MsgSend*() functions can indicate an error of EHOSTDOWN or EHOSTUNREACH if (for example) a send across Qnet failed. 71131
The documentation now states that the name of the runtime linker for MIPS is ldqnx.so.3, instead of ldqnx.so.2 (as it is for other targets). 71087
We've documented the -A and -a options for traceroute, and the -I option for traceroute6. 71064
The entries for aio_cancel(), aio_read(), and aio_write() in the QNX Neutrino Library Reference now include more details about these functions' behavior. 71049
We've corrected the description in the System Architecture guide of how a thread's effective priority is adjusted when it unlocks a mutex. 70960
The documentation for getconf and sysconf() now describes _SC_TZNAME_MAX. 70875

The Multicore Processing chapter of the System Architecture guide now explains why a multicore system with n processors might not always run the n threads with the highest priorities. 70688
The documentation for InterruptDetach() now mentions that the thread that detaches an interrupt handler must be in the same process as the thread that attached it, or else the function indicates an error of EPERM. 70642
The devn-asix.so driver now supports the AX88178 chip. 70621
The pthread_mutex_lock() function's behavior when you try to lock a mutex that you already own depends on the type of the mutex, as described in the documentation for pthread_mutexattr_settype(). Note that pthread_mutexattr_settype() provides a more portable way to make a mutex recursive than pthread_mutexattr_setrecursive() does. 70613
The System Analysis Toolkit User's Guide and the documentation for tracelogger now warn you that if the clocks on a multicore system aren't synchronized, then the timestamps will be inconsistent, and the IDE's System Profiler will be unable to load the data. 70573
The documentation for diskboot now includes the -f, -i, and -R options. 70502
Before using the CACHE_FLUSH() or CACHE_INVAL() macros on ARM and MIPS platforms, a thread must call ThreadCtl( _NTO_TCTL_IO, 0 ); in order to obtain I/O privileges. 70432
The documentation for hogs now points out that the numbers reported are approximate; for precise data, use tracelogger and the System Analysis Toolkit. 70390
The Clocks, Timers, and Getting a Kick Every So Often chapter of Getting Started with QNX Neutrino referred to pthread_mutex_timedlock() in the section on CLOCK_MONOTONIC, but this function uses only CLOCK_REALTIME. This section now refers to timer_create(), which lets you choose the clock source. 70328
The Process Manager chapter of the System Architecture guide now includes a section on locking and superlocking memory. 70211
The documentation for mem_offset() now emphasizes that if the offset is greater than INT_MAX, mem_offset() gives an error of EOVERFLOW. Use mem_offset64() if this happens. 70207
We've corrected the descriptions of snd_pcm_capture_flush() and snd_pcm_playback_flush() in the Audio Developer's Guide. Don't mix and match plugin- and nonplugin-aware functions in your application, or you may get undefined behavior and misleading results. 70196
We've corrected the name of the memopts option in the documentation for devg-flat.so. 70133
MsgSendPulse() indicates an error of EINVAL if the priority is invalid (e.g. 0). 69851
The description in Building Embedded Systems of the qtime field of the system page now recommends that if the clock on your system drifts, you should make sure that the startup code specifies the correct clock frequency. 69812
The Understanding System Limits chapter of the QNX Neutrino User's Guide now includes a section on the limits for Embedded Transaction Filesystems (ETFS). 69786
The section in the Neutrino Programmer's Guide on the /proc filesystem now points out that if you ask for information about a specific thread, and that thread no longer exists, the process manager gives you information about the thread with the next higher thread ID. If all the process's threads have exited, the thread ID in the procfs_status structure is set to 0. 69739
If you call SyncMutexEvent() with a NULL event, the function deletes any existing event registration. 69639
Before calling bind() on an AF_INET socket, set the af_family member of the sockaddr structure to AF_INET. Up until QNX Neutrino 6.4.0, a value of 0 was accepted and assumed to be this value. 69460
If you use MsgSendPulse() to send a pulse across Qnet, the calling thread is blocked (STATE_NET_SEND) while the pulse is delivered to the local Qnet manager, which transmits it to the remote Qnet. The remote Qnet does a MsgSendPulse() on behalf of the caller, and the return value is transmitted back, at which point the calling thread is unblocked. 69256
The default value of Pt_ARG_CBOX_BUTTON_WIDTH is 13, not 17; we've corrected the documentation for PtComboBox. 68983
The syntax for mkdir isn't the same on Windows as on QNX Neutrino. 68912
We've added the -h and -U options to the documentation for telnetd. 68727

We've corrected the diagram of thread states in the QNX Neutrino Microkernel chapter of the System Architecture guide. 68711
We've corrected some numbers that should have been 2nn, not 2nn in the documentation for random() and srandom(). 68648
We've corrected the syntax for applypatch in the Utilities Reference. 68568
The documentation now mentions that if you call MsgSendPulse() with a priority of -1, the function uses the calling thread's priority as the pulse's priority. 68542
We've added more information about the -u option for devf-generic. 68507
We've corrected the example for the mkifs raw attribute: you don't need to specify this attribute in order to keep PhAB resources in an executable. 68428
In the documentation for the IDE User's Guide, the Finding Memory Errors chapter was renamed to “Analyzing Memory Usage and Finding Memory Errors.” In addition, the topics in this chapter were reordered and modified for technical accuracy; many of the topic titles were renamed as well. 68303

The entry for PtTreeChangeItem() in the Widget Reference now points out that this function can return a pointer to a new item that your application must maintain. 67655
The documentation now explains that native io-pkt and ported NetBSD drivers don't put entries into the /dev/io-net namespace, so a waitfor command for such an entry won't work properly in buildfiles or scripts. Use if_up -p instead; for example, instead of waitfor /dev/io-net/en0, use if_up -p en0. 67527
The documentation now mentions that the malloc implementation uses signed, 32-bit integers to represent the size internally, and hence you can't allocate more than 2 GB in a single allocation. If the size is greater than 2 GB, functions such as calloc(), malloc(), and realloc() indicate an error of ENOMEM. 67335
The Sample Buildfiles appendix in Building Embedded Systems now describes how to use ldd, objdump, and the DL_DEBUG environment variable to determine which shared objects to include in an OS image. 66845
It's safe to call tti() from an interrupt handler, but it isn't safe to call ttc() from one; we've updated the documentation for the Character DDK. 66797
The documentation for pthread_cond_timedwait() now recommends that you use CLOCK_MONOTONIC, which isn't affected by changes to the system time that way that CLOCK_REALTIME is. The documentation for sigtimedwait() now mentions that this function uses CLOCK_MONOTONIC to measure the time interval. 66425
We've corrected the information in the Audio Developer's Guide about what snd_pcm_plugin_write() returns. 66265

The documentation for seekdir() now says that if you call rewinddir() on the directory stream, or if you close and reopen the directory, an offset previously returned by telldir() becomes invalid. 39492
The documentation now says that the off argument to mmap() can be a physical address (e.g. for mapping a device's registers in a resource manager). 38626
The System Analysis Toolkit User's Guide now describes the NTO_TRACE_COMM_* events. 38156
The documentation for syslogd now explains when the log entry includes a host name, and when it includes nto (indicating the local host). 29965
The High Availability Framework Developer's Guide now explains how to get a handle for a global entity. 29655
We've corrected the information about the trace events for MsgSendv() in the System Analysis Toolkit User's Guide. 29638
The kernel now reaps zombies, even if you run a foreground process that doesn't exit in your OS image's startup script. However, running a foreground process that never exits still prevents the rest of the script from being executed. 29186
The documentation for if_up now describes the -l option. 28321
The documentation for devf-generic now describes the output produced if you specify the -v option. 27874

The QNX Neutrino Library Reference now describes strtof() and strtold(). 23031
We've corrected the documentation for SignalAction() to say that the default action for SIGTSTP, SIGTTIN, and SIGTTOU is to stop the process, and that you can't ignore or catch SIGCONT. We've also described the special QNX Neutrino signals, which you can't unmask. 22588
If you call a spawn*() function and pass NULL for argv[0] or arg0 (depending on which function you use), the function indicates an error of EINVAL. 22197
The PtFlash was deprecated in QNX Neutrino 6.4.0, but its entry in the Widget Reference wasn't completely removed. We've now fully removed it. 21954
