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.
This utility has an automation support for the Link training tests
(4.3.1.1. - 4.3.2.3), EDID tests (4.2.2.3
- 4.2.2.6) and Video Pattern generation tests (4.3.3.1) from CTS
specification 1.2 Rev 1.1.
This tool has the support for responding to the hotplug uevents
sent by compliance testting unit after each test.
The Linux DUT running this utility must be in text (console) mode
and cannot have any other display manager running. Since this uses
sysfs nodes for kernel interaction, this utility should be run as
Root. Once this user application is up and running, waiting for
test requests, the test appliance software on the windows host
can now be used to execute the compliance tests.
This app is based on some prior work done in April 2015 (by
Todd Previte <tprevite@gmail.com>)
v2:
* Add mode unset on hotplug uevent on disconnect (Manasi Navare)
v3:
