Display Interfaces on |G510-G700-EVK-REF-BOARD|
===============================================

|IOT-YOCTO| supports four display interfaces on |G510-G700-EVK-REF-BOARD|: 

* :ref:`DSI0 <G700-evk-dsi-setup>` with DSI Panel ``STARTEK KD070FHFID015`` on |G700-EVK-REF-BOARD| and DSI Panel ``STARTEK KD070FHFID078`` on |G510-EVK-REF-BOARD| and |G700-EVK-REF-BOARD| p1v4
* :ref:`HDMI <G700-evk-hdmi-setup>`
* :ref:`DisplayPort(DP) <G700-evk-dp-setup>` through USB Type-C port
* :ref:`Embedded Display Port(eDP) <G700-evk-edp-setup>` with eDP Panel ``AUO G156han03``
* :ref:`DSI0 to LVDS <G700-evk-lvds-setup>` with LVDS Panel ``KOE TX18D204VM0BAA``

The display system has two different pipelines - VDOSYS0 and VDOSYS1 - that can be used for any of the dual display combinations.
These pipelines are abstracted as different `crtc` in the DRM framework.

VDOSYS0 provides 3840x2160, 30Hz refresh rate, and VDOSYS1 provides 3840x2160, 60Hz refresh rate.

Default `rity-demo-image` enables dual display DSI0 and HDMI. Other display combinations can be enabled by loading
the `device tree overlay <https://u-boot.readthedocs.io/en/latest/usage/fdt_overlays.html>`_ during the flash programming process.

.. note::

    - DSI1 port (LCM2) is still not supported on |IOT-YOCTO| in v25.x.
    - The LVDS connector is not supported in the v25.x migration. Please refer to the v24.1 implementation. LVDS shares the same data lanes as the eDP connector, so only one of them can be used at a time.

Lists of Display Device Tree Overlay
====================================

Starting from v25, none of the EVK default DTS files enable any display interfaces; loading the relevant DTBOs is required to enable them.
For the G700 EVK, the default configuration loads ``display-dsi.dtbo`` and ``display-hdmi.dtbo``.

.. code-block:: bash

    $ genio-flash -i rity-demo-image
	Genio Tools: v1.7.0a1
	Yocto Image:
        ...
        machine:  genio-700-evk
        overlays: ['display-dsi.dtbo', 'apusys.dtbo', 'display-hdmi.dtbo', 'video.dtbo']

If you do not need ``display-dsi.dtbo``, use the unload-dtbo option to remove the default ``display-dsi.dtbo``

.. code-block:: bash

    $ genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo
	Genio Tools: v1.7.0a1
	Yocto Image:
        ...
        machine:  genio-700-evk
        overlays: ['display-hdmi.dtbo', 'video.dtbo', 'apusys.dtbo']

DSI0 + HDMI
-----------

**DSI0 + HDMI** are the default dual display interfaces for the prebuilt `rity-demo-image`.
A DSI panel is pre-connected to G510/G700 EVK.

Flash the board with:

.. code-block:: bash

    $ genio-flash -i rity-demo-image
	Genio Tools: v1.7.0a1
	Yocto Image:
        ...
        machine:  genio-700-evk
        overlays: ['display-dsi.dtbo', 'apusys.dtbo', 'display-hdmi.dtbo', 'video.dtbo']

As shown in the example above, both ``display-dsi.dtbo`` and ``display-hdmi.dtbo`` are loaded by default.

After boot into the console you can use ``modeprint mediatek`` command to check if both DSI0 and HDMI ports have been properly configured:

.. code-block:: text

    root@genio-700-evk:~# modeprint mediatek
    Starting test
    Resources

    count_connectors : 2
    count_encoders   : 2
    count_crtcs      : 2
    count_fbs        : 0

    Connector: DSI-1
            id             : 32
            encoder id     : 31

            encoders       : 31
    Mode: "1200x1920" 1200x1920 60
    Connector: HDMI-A-1
            id             : 34
            encoder id     : 33
            conn           : connected
            size           : 600x340 (mm)
            count_modes    : 33
            count_props    : 5
            props          : 1 2 5 6 4
            count_encoders : 1
            encoders       : 33
    Mode: "3840x2160" 3840x2160 60
    Mode: "3840x2160" 3840x2160 60
    ...

The associated display data pipeline can process up to 2.5K(2560 x 1600) with 60Hz refresh rate for DSI0, and
4K(3840 x 2160) with 60Hz refresh rate for HDMI.

.. _G700-evk-headless:

Headless
--------

Headless means that Yocto works without enabling any physical display connector.
There is a virtual display at ``/dev/dri/renderD128`` prepared for offline rendering.

To enable Headless, unload the overlay file ``display-dsi.dtbo`` and ``display-hdmi.dtbo`` during flashing process:

.. prompt:: bash

    genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo --unload-dtbo display-hdmi.dtbo

If you don't want to re-flash the entire root file system, you can simply update the overlay configuration with:

.. prompt:: bash

    genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo --unload-dtbo display-hdmi.dtbo kernel mmc0boot1

After boot into the console you will see the following error log which is because there is no physical display for Weston desktop rendering:

.. code-block:: text

    [FAILED] Failed to start Weston, a compositor, as a system service.
    See 'systemctl status weston.service' for details.

You can use ``modeprint mediatek`` command to check if headless has been properly configured by checking if connector count equals 0:

.. code-block:: text

    root@genio-700-evk:~# modeprint mediatek
    Starting test

eDP + DP
--------

You can configure the eDP + DP combination with:

.. prompt:: bash

    genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo --unload-dtbo display-hdmi.dtbo --load-dtbo display-edp.dtbo --load-dtbo display-dp.dtbo

If you don't want to re-flash the entire root file system, you can simply update the overlay configuration with:

.. prompt:: bash

    genio-flash -i rity-demo-image --unload-dtbo display-dsi.dtbo --unload-dtbo display-hdmi.dtbo --load-dtbo display-edp.dtbo --load-dtbo display-dp.dtbo kernel mmc0boot1

After boot into the console you can use ``modeprint mediatek`` command to check if both eDP and DP ports have been properly configured:

.. _G700-evk-edp-setup:

Hardware Setup for eDP
=======================

The prebuilt `rity-demo-image` supports AUO G156HAN03 panel with a eDP cable, as shown below:

.. figure:: /_asset/sw_rity_display_G700_eDP-cable.jpg
    :align: center
    :width: 55%

Please always use this associated cable to connect to the panel. Connect either side to the |G510-G700-EVK| board
and to the panel, as shown below:

.. figure:: /_asset/sw_rity_display_G700_eDP-install.jpg
    :align: center
    :width: 35%

.. _G700-evk-lvds-setup:

Hardware Setup for DSI0 to LVDS
===============================

The prebuilt `rity-demo-image` supports ``DSI0`` to ``IT6122 Converter Daughter Board`` to ``KOE TX18D204VM0BAA panel``.

.. note::

    - The IT6122 Converter Daughter Board doesn't not come with the |G510-G700-EVK| set. Please contact MTK CPM to obtain one.

An example of the daughter board is shown below:

.. figure:: /_asset/sw_rity_display_G700_DSI_to_LVDS_DTB.jpg
    :align: center
    :width: 35%

To install the daughter board, turn both the EVK and the daughter board to the back side, then replace the pre-connected DSI panel LCM0 and CTP0 cables with those on the daughter board.

.. figure:: /_asset/sw_rity_display_G700_DSI_to_LVDS_install_DTB.jpg
    :align: center
    :width: 35%

Turn both the EVK and the daughter board to the front side, then connect the LVDS cable to the daughter board.

A complete setup example is provided below. Note that the DSI panel in the example is not connected to the EVK.

Please note that support for MT8370/MT8390 on |IOT-YOCTO| starts from the ``mtk-v5.15`` kernel and the Yocto ``kirkstone`` branch.
On v25.x, we are using the ``mtk-v6.6`` kernel and the Yocto ``scarthgap`` branch.
