+ *
+ * Displayport Compliance Testing Application
+ *
+ * This is the userspace component of the Displayport Compliance testing
+ * software required for compliance testing of the MSM 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 Qdbox 980
+ * - This user application
+ * - A windows host machine to run the Qdbox 980 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:
+ * - 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:
+ *
+ * msm_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.
+ *
+ * msm_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.
+ *
+ * msm_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 at gmail.com>).
+ *
+ * This work is based upon the intel_dp_compliance.c authored by
+ * Manasi Navare <manasi.d.navare at intel.com>
+ *
+ *
+ * This tool can be run as:
+ * ./msm_dp_compliance It will wait till you start compliance suite from
+ * Qdbox 980.
+ * ./msm_dp_compliance -h This will open the help
+ * ./msm_dp_compliance -i This will provide information about current
+ * connectors/CRTCs. This can be used for debugging purpose.
+ *
+ * Authors:
+ * Abhinav Kumar <abhinavk at codeaurora.org>
+ *
+ * Elements of the modeset code adapted from David Herrmann's
+ * DRM modeset example
