* Displayport Compliance Testing Application
*
* This is the userspace component of the Displayport Compliance testing
* software required for compliance testing of the I915 Display Port driver.
* This must be running in order to successfully complete Display Port
* compliance testing. This app and the kernel code that accompanies it has been
* written to satify the requirements of the Displayport Link CTS 1.2 rev1.1
* specification from VESA. Note that this application does not support eDP
* compliance testing.
*
* Compliance Testing requires several components:
* - A kernel build that contains the patch set for DP compliance support
* - A Displayport Compliance Testing appliance such as Unigraf-DPR120
* - This user application
* - A windows host machine to run the DPR test software
* - Root access on the DUT due to the use of sysfs utility
*
* Test Setup:
* It is strongly recommended that the windows host, test appliance and DUT
* be freshly restarted before any testing begins to ensure that any previous
* configurations and settings will not interfere with test process. 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
* (<tprevite@gmail.com>)
*
*
* 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. This can be used for debugging purpose.
*
* Authors:
* Manasi Navare <manasi.d.navare@intel.com>
*
* Elements of the modeset code adapted from David Herrmann's
* DRM modeset example
