What's in this TDK?

This TDK contains normal and instrumented versions of the QNX Neutrino microkernel (procnto) for x86, MIPS, and PowerPC (600 and 700 series) platforms.

These files are installed under $QNX_TARGET/:

  • x86/boot/sys/procnto-smp
  • x86/boot/sys/procnto-smp-instr
  • mipsbe/boot/sys/procnto-smp
  • mipsbe/boot/sys/procnto-smp-instr
  • mipsle/boot/sys/procnto-smp
  • mipsle/boot/sys/procnto-smp-instr
  • ppcbe/boot/sys/procnto-600-smp
  • ppcbe/boot/sys/procnto-600-smp-instr

Fixed issues

  • procnto-smp no longer has random faults on the Atlantis (PPCBE) board. (Ref# 17512)
  • ksh can now successfully create child processes all the time. (Ref# 24342)
  • procnto-600-smp no longer crashes with the devn-mv64360.so driver. (Ref# 20832)
  • Using ksh or sed no longer causes procnto-smp to shut down. (Ref# 27976)
  • Using pipelines or setpgid() on a terminating process no longer makes procnto-smp become deadlocked. (Ref# 23481)
  • Using the new asynchronous I/O library libaio on an SMP machine no longer deadlocks the client. (Ref# 21139)
  • Using vfork() no longer shuts down procnto-smp on x86 targets. (Ref# 27761)

Known issues

  • A potential deadlock exists in the malloc library when you're using vfork() and exec() if the vforked child receives a termination signal while holding the malloc library mutex. (Ref# 28161)
  • FIFO scheduling isn't always honored with SMP. Applications that rely on FIFO scheduling (run-to-completion model) won't execute properly. (Ref# 29847)

Be sure to check the QNX Neutrino Core OS 6.3.2 release notes for related issues.

Documentation

The functionality provided by the TDKs is already described within the QNX Momentics documentation set. For information on the Multicore Technology Development Kit, see:
