The intention of this test is use it to test that the CI system
that runs IGT is collecting the results correctly.

+ * The purpose of this test is to test the CI system that we have
+ * for running the tests. The test should generate all possible
+ * exit states for igt tests.
+ *
+ * Possible exit-states of igt tests:
+ * 1. pass - subtest: pass-result
+ * 2. fail - subtest: fail-result
+ * 3. dmesg warn - subtest: dmesg-fail,
+ * subtest: dmesg-pass is a sanity check for the dmesg-fail.
+ * 4. crash - subtest: user-crash
+ * 5. piglit timeout - subtest: piglit-timeout
+ * 6. incomplete - subtest: generate-panic
+ * NOTE: inorder for this to generate the incomplete state
+ * the kernel must be configured to reboot on panic.
+ * NOTE: if the tested CI system have features such as
+ * PSTORE and/or kexec/kdump enabled. This test could be
+ * used to make sure that the CI system stores the generated
+ * log/dumps as expected.
+ * 7. incomplete - where user hang is not caught by piglit timeout.
+ * This would be caught by a user-side softdog daemon,
+ * such as owatch by ezbench. However, I don't know
+ * how to trigger this state, so it will not be tested.
+ * 8. incomplete - system requires hard reboot :
+ * This state could be triggered by calling an evil kernel
+ * module that was developed hang the system. Such
+ * a module will not be developed for this purpose,
+ * so this "exit state" will not be tested.
+ *
+ * TODO: If this test was deployed on a CI system that
+ * was able to pick up testing again after reboot,
+ * such as ezbench, a post-analyze test should be added
+ * that collected and analyzed the result of the tests
+ * run before reboot.
