+The recipes-rt recipes provide package and image recipes for using and testing

+a couple extra packages, including rt-tests. In order to build the image with

+Upstream-Status: Submitted
+
+Allow users (build systems) to specify PYLIB. This allows for a

+PYLIB.

+
+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.

+Subject: [PATCH 1/1] cyclictest: finish removal of 1 second first loops
+
+Observation:
+Huge latencies reported close to 1 second when certain options
+are used in cyclictest.
+
+Problem:
+[ commit da4956cbcaf7945554f30e4d3a9be09b1431b19a
+    use interval on first loop instead of 1 second ]
+removed the 1 second first timing loop out of the main path
+in cyclictest but left it in two other paths, namely the ones
+triggered by these two options:
+-r       --relative        use relative timer instead of absolute
+-s       --system          use sys_nanosleep and sys_setitimer
+This causes huge latencies of close to 1 second to be reported
+by cyclictest with certain uses of those two options.
+
+Fix:
+Extend the original commit to remove the 1 second hardcoded
+timer values from the RELTIME and ITIMER options.  Use the
+the actual interval instead.
+
+Upstream-Status:  Accepted
+[ https://git.kernel.org/cgit/linux/kernel/git/clrkwllms/rt-tests.git/commit/?h=work&id=1b92da30837e9552aba209cbdf938877f0fd3bbf ]

+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.
