config: rt-tests: set default priority of rt-migrate test
5af56c0 
The priority of 96 if passed to rt-migrate causes failure. The test
isn't designed well to handle high priority of 96. The test takes this
priority and adds the count of number of tasks which becomes greater
than 99. The 99 is the highest priority level for SCHED_FIFO. Hence,
the priority setting of the main thread fails, we get warning and later
test failure:

  Warning, can't set priority of main thread!

Instead of fixing the test at this time, let's use priority of 90
instead of 96 such that the total priority of main thread remains below
highest priority level. We can set any other lower priority than 90 here
as well such as 51 which is set in the rt-migrate-test.sh by default.

config: rt-tests: fix MLOCKALL getting set to True
79c6b9d 
When MLOCKALL is set to 'true', the lava job has MLOCKALL becomes true
[1] which in turn translates to "True" while job execution [2]. It
causes error as the test expects true instead of True.

  ./pi-stress.sh -D 60s -m True -r false -w hackbench
  ./pi-stress.sh: 37: True: not found

Fix it by using double quotes instead.

Fix it by using double quotes inside single quotes.
- First set of quotations allows Jinja template engine to treat it as a
  string
- Second set is for LAVA to also treat is as string and prevent YAML
  parser from making it a bool

[3] is successful job after this change.

I'm checking the results after merging Linaro/test-definitions#530. We use https://github.com/kernelci/test-definitions in our jobs. I don't know why we have forked the original repository. I'll ask around and get the fork updated and re-run to get the latest results.

rt-tests0.html.txt

I ran all tests on the stable-rt v6.6-rt branch and all tests are passing. (Convert above file to html and view for results)

We use rtla package from debian respository to run 2 tests (osnoise and timerlat). This tools is present in the mainline (tools/tracing/rtla). We should install the latest tool from mainline instead of installing from debian package. Because of old package, these tests are partially run. I'll create a separate ticket for this.
