In bringup on simulated HW even rudimentary tests are slow, and so many may fail that we want to be able to filter out the noise to focus on the specific problem. Even just the tests groups provided for igt is not specific enough, and we would like to isolate one particular subtest (and probably subsubtests!). For simplicity, allow the user to provide a command line parameter such as i915.st_filter=i915_timeline_mock_selftests/igt_sync to restrict ourselves to only running on subtest. The exact name to use is given during a normal run, highlighted as an error if it failed, debug otherwise. The test group is optional, and then all subtests are compared for an exact match with the filter (most subtests have unique names). The filter can be negated, e.g. i915.st_filter=!igt_sync and then all tests but those that match will be run. More than one match can be supplied separated by a comma, e.g. i915.st_filter=igt_vma_create,igt_vma_pin1 to only run those specified, or i915.st_filter=!igt_vma_create,!igt_vma_pin1 to run all but those named. Mixing a blacklist and whitelist will only execute those subtests matching the whitelist so long as they are previously excluded in the blacklist.
