Subject: [ANNOUNCE] rt-tests-v0.97


Dear RT Folks

We are pleased to announce the latest version of rt-tests

We have a number of interesting enhancements.

Firstly Clark has formally removed the requirement to compile hwlatdetect as a module.

Daniel Bristot de Oliveira has added a hardware SMI count detection using 
the MSR/SMI counter if available. Using the --smi option adds the count to 
the end of the output, it looks like this (per thread)

 T: 0 ( 2285) P:80 I:1000 C:   9975 Min:      2 Act:    3 Avg:    4 Max:   20831 SMI:       2

Finally Luis Capitulino has added an option to bypass cyclictest's built-in tracing so that this functionality can be handed off to another program - in particular trace-cmd. cyclictest continues to write to the /sys/kernel/debug/tracing/trace_maker file, but trace-cmd handles the tracing.

trace-cmd record [...] cyclictest [...] -bX --tracemark

We are nearing a 1.0 version of rt-tests.
I'd like to have a round of bugfix/clean-up  patches, and patches to add anything 
missing and then create a 1.0 version of rt-tests that we will continue to maintain,
 but that won't accept any new enhancements. We will also spin-off a development version (v2.x?) that will allow api changes.

In the development version we are planning on ripping out the built-in tracing support for tighter integration with trace-cmd.
The options in cyclictest have also become quite crufty and complicated and 
need to be radically reworked / simplified. The tests could also share code much better than they currently do.

To fetch the latest version

Clone one of the following if needed.

https://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git
https://kernel.googlesource.com/pub/scm/utils/rt-tests/rt-tests.git

tag: v0.97

You can also fetch the tarball here

https://www.kernel.org/pub/linux/utils/rt-tests/rt-tests-0.97.tar.gz

older versions are in
https://www.kernel.org/pub/linux/utils/rt-tests/rt-tests/older

I have created a new devel branch which will beome 1.0 (unless we need a v0.99)

devel/v0.98

I'll create the development line for 2.0 once we freeze 1.0

Thanks for all your hardwork

Cheers!
