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 small 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. Signed-off-by: Paulo Zanoni --- tests/.gitignore | 1 + tests/Makefile.sources | 1 + tests/kms_frontbuffer_tracking.c | 1825 ++++++++++++++++++++++++++++++++++++++ 3 files changed, 1827 insertions(+) create mode 100644 tests/kms_frontbuffer_tracking.c Some interesting details: On a tree from 2015, May 06, I get 18 failures and 357 successes. The only FBC failures I get are from the MMAP_WC draw method, which is maybe lacking proper frontbuffer tracking support on the Kernel. The other 16 failures are for PSR, most of them with GTT MMAPs. But if I use a tree from 2015, May 25, every single PSR test fails. We need to investigate that. Maybe if I had finished this earlier we would have an automated bisect. This also highlights the importance of testing stuff even when they are disabled by default! I plan to patch the other tests to do the same thing. I am also seeing some FBC failures that happen right after booting. It seems that the very first tests fail until I run a test that uses the render ring. I'll have to investigate this. I am also seeing some occasional corruptions on my eDP panel, but on these cases both the pipe and sink CRC tests succeed! Maybe this is some weird panel malfunction caused by the fact that we're doing tons and tons of modesets on the panel. diff --git a/tests/.gitignore b/tests/.gitignore index a3f3143..dcead2c 100644 --- a/tests/.gitignore +++ b/tests/.gitignore @@ -134,6 +134,7 @@ kms_flip kms_flip_event_leak kms_flip_tiling kms_force_connector +kms_frontbuffer_tracking kms_legacy_colorkey kms_mmio_vs_cs_flip kms_pipe_b_c_ivb diff --git a/tests/Makefile.sources b/tests/Makefile.sources index 994c31b..3c93337 100644 --- a/tests/Makefile.sources +++ b/tests/Makefile.sources @@ -66,6 +66,7 @@ TESTS_progs_M = \ kms_flip \ kms_flip_event_leak \ kms_flip_tiling \ + kms_frontbuffer_tracking \ kms_legacy_colorkey \ kms_mmio_vs_cs_flip \ kms_pipe_b_c_ivb \ diff --git a/tests/kms_frontbuffer_tracking.c b/tests/kms_frontbuffer_tracking.c new file mode 100644 index 0000000..f6554f9 --- /dev/null +++ b/tests/kms_frontbuffer_tracking.c @@ -0,0 +1,1825 @@ +/* + * Copyright © 2015 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
