From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx>
This is a new test that should exercise the frontbuffer tracking
feature of the Kernel in a number of different ways. We use different
drawing methods, we use the primary, cursor and sprite planes, we can
test both on single and dual pipes, also on buffers not associated
with any CRTCs, etc.
We currently have assertions for both FBC and PSR, and we also have a
"nop" test mode that should disable both FBC and PSR, and can be
used for debugging.
This test is also capable of testing both FBC and PSR even if they are
disabled by default on the Kernel: the test knows how to change the
i915.ko parameters and then set them back after testing.
I am getting a significant number of failures when I run this test,
which means we have some work to do on the Kernel.
I also still have a small list of additional subtests that I plan to
add to this test, and those tests are documented on the main function.
v2:
- Use igt_debugfs_open() (Thomas).
- Use igt_test_description() (Thomas).
- Don't check drm_open_any_master()'s result (Thomas).
- Use igt_require_f() in some cases (Thomas).
- Standardize some assertions.
- Use the new module param functions.
- Check if FBC is supported by the chipset.
- Add new subtests (multidraw, enum fbs, fbc+psr).
- Make tests a little shorter.
- Reorganize which tests ara ran by default.
- Better comments everywhere.
- Rebase.

+IGT_TEST_DESCRIPTION("Test the Kernel's frontbuffer tracking mechanism and "
+ "its related features: FBC and PSR");
+
+/*
+ * One of the aspects of this test is that, for every subtest, we try different
+ * combinations of the parameters defined by the struct below. Because of this,
+ * a single addition of a new parameter or subtest function can lead to hundreds
+ * of new subtests.
+ *
+ * In order to reduce the number combinations we cut the cases that don't make
+ * sense, such as writing on the secondary screen when there is only a single
+ * pipe, or flipping when the target is the offscreen buffer. We also hide some
+ * combinations that are somewhat redundant and don't add much value to the
+ * test. For example, since we already do the offscreen testing with a single
+ * pipe enabled, there's no much value in doing it again with dual pipes. If you
+ * still want to try these redundant tests, you need to use the --show-hidden
+ * option.
+ *
+ * The most important hidden thing is the FEATURE_NONE set of tests. Whenever
+ * you get a failure on any test, it is important to check whether the same test
+ * fails with FEATURE_NONE - replace the feature name for "nop". If the nop test
+ * also fails, then it's likely the problem will be on the IGT side instead of
+ * the Kernel side. We don't expose this set of tests by default because (i)
+ * they take a long time to test; and (ii) if the feature tests work, then it's
+ * very likely that the nop tests will also work.
