+Displayport Compliance Testing
+Userspace Application
+
+This is the userspace portion of the Displayport Compliance testing suite for the
+i915 driver. It must be running in order to successfully complete Displayport
+compliance testing. This file contains the latest available information about
+the user app and its operation.
+
+This app and the kernel code that accompanies it has been written to satisfy the
+requirements of the Displayport Link CTS Core 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 the Unigraf DPR-100,
+ DPR-120 or Quantum Data 882EDP
+ - This user application
+ - A Windows host machine to run the test software
+ - Root access on the DUT
+
+Test setup:
+ It is strongly recommended that the Windows host, test appliance and DUT be freshly
+ restarted before testing begins. This ensures that any previous configurations and
+ settings will not interfere with the 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. The easiest way to accomplish this is to place the word “text”
+ on the command line for booting the kernel. The recommended boot parameters for
+ the kernel are as follows:
+ “test debug drm.debug=0x0e”
s/test/text/

Good catch, Dave, thank you! I'll get that fixed immediately.
