+smp
+---
+
+Another NSH configuration, similar to nsh, but also enables
+SMP operation. It differs from the nsh configuration only in these
+additional settings:
+
+SMP is enabled::
+
+ CONFIG_SMP=y
+ CONFIG_SMP_IDLETHREAD_STACKSIZE=3072
+ CONFIG_SMP_NCPUS=2
+ CONFIG_SPINLOCK=y
+
+The apps/testing/smp test is included::
+
+ CONFIG_TESTING_SMP=y
+ CONFIG_TESTING_SMP_NBARRIER_THREADS=8
+ CONFIG_TESTING_SMP_PRIORITY=100
+ CONFIG_TESTING_SMP_STACKSIZE=2048
+
+ostest
+------
+
+This is the NuttX test at apps/examples/ostest that is run against all new
+architecture ports to assure a correct implementation of the OS. The default
+version is for a single CPU but can be modified for an SMP test by adding::
+
+ CONFIG_SMP=y
+ CONFIG_SMP_IDLETHREAD_STACKSIZE=2048
+ CONFIG_SMP_NCPUS=2
+ CONFIG_SPINLOCK=y
+
+NOTES:
+
+ 1. See NOTES for the nsh configuration.
+ 2. 2016-12-23: Test appears to be fully functional in the single CPU mode.
+ 3. 2016-12-24: But when SMP is enabled, there is a consistent, repeatable
+ crash in the waitpid() test. At the time of the crash, there is
+ extensive memory corruption and a user exception occurs (cause=28).
Review comment:
I'll remove it. Yeah, really don't like embedding these kind of notes in
the docs. I would just have an open issue for it.
