+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

+Allow users (build systems) to specify PYLIB. This allows for a

+
+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
+performance. So we keep it as a union but only check error against -1. There is
+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 | | | |
+# | 118 | | | | |
+# | 119 | 119 | 119 | | |
+# | 138 | | | | |
+# | 57 | 138 | | | |
+# | 175 | | | | |
+# | 130 | 175 | 175 | 175 | |
+# | 54 | | | | |
+# | 150 | 150 | | | |
+# | 47 | | | | |
+# | 59 | 59 | 150 | | |
+# | 199 | | | | |
+# | 115 | 199 | | | |
+# | 177 | | | | |
+# | 129 | 177 | 199 | 199 | 199 |
+#
+# 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.
