Refer to + * the test appliance documentation for setup, software installation and + * operation specific to that device. + * + * The Linux DUT must be in text (console) mode and cannot have any other + * display manager running. You must be logged in as root to run this user app. + * Once the user application is up and running, waiting for test requests, the + * software on the windows host can now be used to execute the compliance tests. + * + * This userspace application supports following tests from the DP CTS Spec + * Rev 1.1: + * - Link Training Tests: Supports tests 4.3.1.1 to 4.3.2.3 + * - EDID Tests: Supports EDID read (4.2.2.3),EDID Read failure and corruption + * detection tests (4.2.2.4, 4.2.2.5, 4.2.2.6) + * - Video Pattern generation tests: This supports only the 24 and 18bpp color + * ramp test pattern (4.3.3.1). + * + * Connections (required): + * - Test Appliance connected to the external Displayport connector on the DUT + * - Test Appliance Monitor Out connected to Displayport connector on the + * monitor + * - Test appliance connected to the Windows Host via USB + * + * Debugfs Files: + * The file root for all the debugfs file: + * /sys/kernel/debug/dri/0/ + * + * The specific files are as follows: + * + * i915_dp_test_active + * A simple flag that indicates whether or not compliance testing is currently + * active in the kernel. This flag is polled by userspace and once set, invokes + * the test handler in the user app. This flag is set by the test handler in the + * kernel after reading the registers requested by the test appliance. + * + * i915_dp_test_data + * Test data is used by the kernel to pass parameters to the user app. Eg: In + * case of EDID tests, the data that is delivered to the userspace is the video + * mode to be set for the test. + * In case of video pattern test, the data that is delivered to the userspace is + * the width and height of the test pattern and the bits per color value. + * + * i915_dp_test_type + * The test type variable instructs the user app as to what the requested test + * was from the sink device. These values defined at the top of the application's + * main implementation file must be kept in sync with the values defined in the + * kernel's drm_dp_helper.h file. + * This app is based on some prior work submitted in April 2015 by Todd Previte + * () + * + * + * This tool can be run as: + * ./intel_dp_compliance It will wait till you start compliance suite from + * DPR 120. + * ./intel_dp_compliance -h This will open the help + * ./intel_dp_compliance -i This will provide information about current + * connectors/CRTCs.
