From 7889b6a86c22878a27344b39a818cf7a42f57895 Mon Sep 17 00:00:00 2001 From: Ramalingam C Date: Mon, 22 Oct 2018 22:35:40 +0530 Subject: kms_content_protection: Add Content Protection test Pretty simple test: - picks the hdcp capable output with suitable pipe and apply modeset. - checks the connected sink's hdcp capability through debugfs - apply a FB and wait for the flip completion. - clears the content protection property - verifies that it clears - sets the content protection property to desired - verifies that it transitions to enabled - incase of timeout three reattempts are implemented - clear the content protection property and modeset on the crtc Above steps are repeated on all HDCP capable connectors for both legacy and atomic subtests. v2: dynamic subtests are dropped [Daniel] v3: debugfs is used to detect the sink's hdcp capability [Daniel] data structure is made as global variable. v4: debugfs file from connector's debugfs dir is used [Daniel] v5: i915_debugfs_connector_dir() usage is modified [Chris] Signed-off-by: Sean Paul Signed-off-by: Ramalingam C Reviewed-by: Daniel Vetter Signed-off-by: Daniel Vetter --- tests/kms_content_protection.c | 302 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 302 insertions(+) create mode 100644 tests/kms_content_protection.c (limited to 'tests/kms_content_protection.c') diff --git a/tests/kms_content_protection.c b/tests/kms_content_protection.c new file mode 100644 index 00000000..47acbeed --- /dev/null +++ b/tests/kms_content_protection.c @@ -0,0 +1,302 @@ +/* + * Copyright © 2018 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.
