New tests
---------

  New tests have been introduced between IGT_6513 and IGTPW_7252:

### New IGT tests (1) ###

  * igt@meta_test@fail-result:
    - Statuses : 40 fail(s)
    - Exec time: [0.00, 0.23] s

  

  {name}: This element is suppressed. This means it is ignored when computing
          the status of the difference (SUCCESS, WARNING, or FAILURE).

This can be improved a little: Add subtests descriptions.

Please do not write down exact code steps taken, rather than
that try to describe what subtest is doing. Search for
igt_describe inside lib/igt_core.h for tips. You may also run
git log to see history (maybe with -p option):

git log tests/i915/gem_exec_fair.c

Other way you can try reaching to developer(s) who written these
tests, for example on irc, or search mailing list history.

Last one, after you add description, compile it and run with:

sudo ./gem_exec_fair --describe

to see what other ones are missing.

imho this one also needs improvement. You can work on other
descriptions step by step, just extend this patch, so it will
be only one patch per test file.
