+The recipes-rt recipes provide package and image recipes for using and testing
+the PREEMPT_RT kernel. The core-image-rt*.bb images are minimal images with
+a couple extra packages, including rt-tests. In order to build the image with
+the linux-yocto-rt kernel, be sure to include the following line in your
+local.conf, bblayers.conf, or your $MACHINE.conf.
+
+PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-rt"
+
+If you are creating a new BSP which should use linux-yocto-rt by default,
+use the line above in the $MACHINE.conf in your BSP layer, and specify the
+following in a linux-yocto-rt bbappend recipe:

+
+Upstream-Status: Submitted
+
+Allow hwlatdetect to be installed independently of the rest of the
+tests. This is convenient for build systems that package it separately
+due to the python dependency.

+childinfo_t is a union that contains both signed (error) and unsigned
+(threadid) members. Thus a large threadid could appear as a negative error
+value, which will cause unexpected failures.
+
+childinfo_t should be changed to a struct, but it could potentially affect the

+still a chance of false alarm but it's small.

+# The script measures interrupt latency together with different types of
+# system load. This is done using the programs cyclictest and stress.
+#
+# The main output is:
+#
+#   Best case (min) latency
+#     This has very limited value, but is presented since it can be done
+#     easily
+#
+#   Average latency
+#     This value is of interrest for throughput oriented systems. Limited
+#     value for a real-time system. Also presented because it is easy to do.
+#
+#   Worst case (max) latency
+#     This is the interesting number for a real-time system. The number
+#     presented is (of cource) the largest number observed. The challenge
+#     is to know how the observed worst case relates to the actual worst case.
+#
+#     To get an indication of the confidence, the following method is used:
+#     1) Instead of one long run, the measurement is made as a set of shorter
+#        runs. The number of runs must be a power of 2 for reasons that will
+#        shorlty be obvious
+#
+#     2) First, a list of the max values are created.
+#
+#     3) The smallest value in that list is recorded.
+#
+#     4) Then a new list is create by taking the max value of each pair of
+#        values in the original list. In this list the smallest value is
+#        recorded.
+#
+#     5) Step 3 is repeated until there is only one value in the list. See
+#        example below:
+#
+#        Samples:
+#          |  44 |     |     |     |     |
+#          |  77 |  77 |     |     |     |

+#
+#        Smallest value:
+#          |  44 |  59 | 119 | 175 | 199 |
+#
+#     6) The generated list of smallest values is analyzed. In this case, it
+#        can be observed that the values are increasing significantly through
+#        the entire list, which leads to the conclusion that the number of
+#        samples is too small.
+#        If instead the list had been (167, 191, 196, 199, 199), there had
+#        been a very small, or no, increase at the end of the list. We might
+#        then suspect that the number of samples is probably large enough.
+#        There is however no guarantee for that.
+#
+#     Steps 1-2 are done in run_cyclictest_suite
+#     Steps 3-5 are done in gen_minmax_list.
+#     Step 6 needs to be done manually since there is (yet) no well defined
+#     FAIL criterion and a theoretically solid PASS criterion may never be
+#     available.
