Subject: [ANNOUNCE] New release rt-tests-1.4

We haven't had a release in a while as people were content to work from 
git. However, in order to make it easier to use, test, and put into 
distributions, now would be a good time for an official release.

There have been a number of interesting changes since 1.3

I'm happy with the way the removal of the --numa from cyclictest is 
working now. What this means is that numa is dectected automatically, so 
you don't have to specify it. You can still force smp with --smp though.

In addition, cpu affinity should work correctly now. Historically there 
were combinations of options in which you couldn't specify cpu affinity, 
but these restrictions have been removed.

We have added a number of new programs to the rt-tests suite

- queuelat
- cyclicdeadline
- deadline_test
- ssdd

queuelat simulates a network queue checking for latency violations in
packet processing.

deadline_test is used to test the deadline scheduler (SCHED_DEADLINE)
cyclicdeadline also tests the deadline scheduler in a cyclictest manner

ssdd has a tracer do a bunch of PTRACE_SINGLESTEPs

There is a new feature that adds a duration option to many of the tests
as a more natural way that iterations to determine how long to test for.

There have also been a number of fix and updates, such as an update.
hwlatdetect no-longer requires a kernel module, instead it uses ftrace.
It also works with python3

CPU counters with SMI counter support has been updated, although I think 
we're due for another. Hint to Daniel :)

So the latest stable / unstable branch (yes the naming is confusing, and 
this will be changed in the future too) is

unstable/devel/latest
If you just to want to use or test the latest then use that

Development for the above is happening here
unstable/devel/latest-devel

This already has some new patches for the deadline tests
This is what developers should development against until
I merge it back into the latest.

Bug reports and patches, are all welcome.

I'd like to step up development, especially bug fixes, and
harden this up. Everything is working reasonably well, but
I'm sure with everyone working the code we can flush out some bugs
and aim for a new stable branch.

So, have fun, and send in your patches and reports!

John Kacur
