The author provides Debian GNU / Linux for Ultra96 / Ultra96-V2 (ZynqMP) . The Debian GNU / Linux provided is CUI-based, but this time we have made the X Window System run on Ultra96 / Ultra96-V2 to support the GUI.
Therefore, the procedure for operating the X Window System on Ultra96 / Ultra96-V2 is explained in several parts.
This article provides steps to build the Debian Package for the Video Driver (xserver-xorg-video-armsoc-xilinx) and install it on ZynqMP-FPGA-Linux.
A DDX Driver (Video Driver) for the X Window Server that supports ZynqMP. You can get display information and set the display through DRM / KMS (Kernel Module Setting) of Kernel Module (xlnx_drv) provided by Xilinx.
This chapter provides steps to create a Debian Package for xserver-xorg-video-armsoc-xilinx.
The repository generated by the procedure explained here is prepared at the following URL. If you have trouble creating a repository, please use the following repository.
We also have a pre-built xserver-xorg-video-armsoc-xilinx Debian Package in the following repositories. If you have trouble building, please use this.
There is one caveat to the build environment. That is, xserver-xorg-video-armsoc-xilinx must be built as a plugin module for xserver-xorg-core. To do this, you need an environment where you have built xserver-xorg-core. At that time, if the target environment (in this case Debian 10 (ARM64)) and the build environment (for example, Ubuntu (amd64)) are different, problems such as not being able to build normally may occur.
The quickest way to solve this problem is to (self) build xserver-xorg-video-armsoc on Debian 10 running Ultra96 / Ultra96-V2. This article describes the steps to build on Debian 10 running Ultra96 / Ultra96-V2.
xserver-xorg-video-armsoc-xilinx is based on xf86-video-armsoc. However, there are actually several versions of xf86-video-armsoc. You can find 32 repositories just by searching on github. In addition to github, there are git repositories on Linaro.org and freedesktop.org. It's a mixture of hundreds of flowers and boulders. Below is a brief introduction to the repositories found.
Of the repositories listed above, xserver-xorg-video-armsoc-xilinx uses the one provided by freedesktop.org. I chose this repository because it is (probably) used by PetaLinux provided by Xilinx. I've tried other repositories, but none of them build or display well.
The freedesktop.org repository is not github and cannot be forked. Therefore, create a local repository by following the steps below.
shell$ mkdir xserver-xorg-video-armsoc-xilinx shell$ cd xserver-xorg-video-armsoc-xilinx shell$ git init shell$ git remote add freedesktop https://anongit.freedesktop.org/git/xorg/driver/xf86-video-armsoc.git shell$ git fetch freedesktop shell$ git merge freedesktop
Xilinx's PetaLinux is built by patching the repository provided by freedesktop.org. The patch file can be found at the following URL:
Download this patch file and patch the repository. I also do a git commit.

Create a debian directory and add the following files.
These files are not described here. See https://github.com/ikwzm/xf86-video-armsoc-xilinx for more information.
After adding the file, git commit.
shell$ git add debian/ shell$ git commit -m "[add] debian/" [master 3961b1d] [add] debian/ 8 files changed, 68 insertions(+) create mode 100644 debian/README.Debian create mode 100644 debian/README.source create mode 100644 debian/changelog create mode 100644 debian/compat create mode 100644 debian/control create mode 100644 debian/copyright create mode 100755 debian/rules create mode 100644 debian/xserver-xorg-video-armsoc-xilinx.docs create mode 100644 debian/xserver-xorg-video-armsoc-xilinx.install
The following packages are required to build the Debian Package for xserver-xorg-video-armsoc. Please install with apt install.
First run autogen.sh to generate configure and Makefile. You must then run make distclean to clear the intermediate files generated by autogen.sh.
shell$ autogen.sh : Omission : shell$ make distclean : Omission
Run debian / rule binary to build the Debian Package for xserver-xorg-video-armsoc-xilinx. The built package will be created in the directory one level above.
shell$ sudo debian/rule binary : Omission : shell$ dpkg --info ../xserver-xorg-video-armsoc-xilinx_1.4-1_arm64.deb new Debian package, version 2.0. size 32924 bytes: control archive=856 bytes. 540 bytes, 12 lines control 611 bytes, 7 lines md5sums Package: xserver-xorg-video-armsoc-xilinx Source: xf86-video-armsoc-xilinx Version: 1.4-1 Architecture: arm64 Maintainer: ikwzm <[email protected]> Installed-Size: 100 Depends: libc6 (>= 2.17), libdrm2 (>= 2.4.36), libpixman-1-0, xorg-video-abi-24, xserver-xorg-core (>= 2:188.8.131.521) Provides: xorg-driver-video Section: x11 Priority: optional Homepage: <https://github.com/ikwzm/xf86-video-armsoc-xilinx> Description: X.Org X Server -- ARM SoC display driver for rockchip, amlogic, sunxi and Xilinx(ZynqMP) DRM (mainline kernel)
This section describes the steps to install the xserver-xorg-video-armsoc-xilinx Debian Package built in the previous chapter on ZynqMP-FPGA-Linux.
The pre-built Debian Package is available in the following repositories. You can install this.
The procedure to install here is when rendering by GPU (Mali-400) is not performed. Rendering on the GPU requires the installation of the libMali and Mali Kernel drivers, which complicates the installation process. Please refer to the following article for details.
First, install the X Window System.
shell$ apt install x-window-system-core : Omission
Then install xserver-xorg-video-armsoc-xilinx_1.4-1_arm64.deb.
shell$ sudo dpkg -i xserver-xorg-video-armsoc-xilinx_1.4-1_arm64.deb [sudo] password for fpga: (Reading database ... 66644 files and directories currently installed.)

Install your favorite window manager.
shell$ apt install jwm : Omission
You must specify armsoc for the Driver property in the Device section of /etc/X11/xorg.conf.
Section "Device" Identifier "ZynqMP" Driver "armsoc" Option "DEBUG" "true" EndSection Section "Screen" Identifier "DefaultScreen" Device "ZynqMP" EndSection
Log in as root and try starting with startx.
shell# startx & : Omission
If you see X Windows on your display, you're good to go.
