Dear RT Folks
We are pleased to announce the latest version of rt-tests
There is the usual round of clean-ups.
- we are continuing to improve the make system
- Henrik cleaned up the new feature to run cyclictest in Android
specifically he removed all the ugly #ifdefs to an android specific file
There is a new feature to trace information about latency spikes,
to see if we can find any patterns to the spikes
Here is what a sample run with the new feature looks like. (non-rt kernel)
su -c './cyclictest -t4 -p99 --spike=30 --duration=60'
