graphics improvement for arm mali GPU's users

this is a guide to compile graphic drivers in your termux with ubuntu-on-android

• You can improve graphic up to a good extend than the normal proot environment
• See the results

Requirements

• termux app with proot and Linux installed (recommended ubuntu-on-android)
• No root required
• supported mali GPU's

GPU	Architecture	OpenGL ES	OpenGL
Mali T720	Midgard(v4)	2.0	2.1
Mali T760	Midgard(v5)	3.1	3.1
Mali T820	Midgard(v5)	3.1	3.1
Mali T860	Midgard(v5)	3.1	3.1
Mali G72	Bifrost(v6)	3.1	3.1
Mali G31	Bifrost(v7)	3.1	3.1
Mali G52	Bifrost(v8)	3.1	2.1

You can check your's GPU model in apps like aid64-> Display -> GPU Renderer

we are going to use mesa -> panforst gallium driver which makes a llvmpipe to actual GPU

• About penforst

The Panfrost driver stack includes a non-conformant OpenGL ES implementation for Arm Mali GPUs based on the Midgard and Bifrost microarchitectures

This steps has to be done in a proot-environment

1 building and installing

1.1 Getting mesa from Github

apt install git -y
git clone https://github.com/mesa3d/mesa

1.2 setting up build dependencies

edit apt sources /etc/apt/sources.list and append deb-src http://ports.ubuntu.com/ubuntu-ports/ hirsute main restricted and save the file next update apt indexes

apt update

now go to the directory where you cloned mesa and build dependencies with this command

apt-get build-dep mesa

For others

zypper source-install --build-deps-only Mesa # openSUSE/SLED/SLES
yum-builddep mesa # yum Fedora, OpenSuse(?)
dnf builddep mesa # dnf Fedora

1.3 building

cd to mesa folder cd mesa, and start compiling with this command

meson . build/ -Ddri-drivers= -Dvulkan-drivers= -Dgallium-drivers=panfrost -Dllvm=false

if you have dri drivers and Vulkan drivers for your device the add their path or leave it empty like above command

1.4 installing

After you are done with building next is to install it cd to your build directory cd build then run this

sudo ninja install

Now this one take some time depending on your device speed so take a break.

1.5 Final step

after its done installing it stores library at /lib or /lib64 or /usr/local/lib directory make sure you read last output lines to know your's we need to export the path to env variable LD_LIBRARY_PATH

For my aarch64 device, it is like this

export LD_LIBRARY_PATH=/lib/aarch64-linux-gnu/

this varible unset's in new session so append this line in your bashrc file

echo "export LD_LIBRARY_PATH=/lib/aarch64-linux-gnu/" >> ~/.bashrc

Now you can start your vnc with llvmpiped and experience some smooth feel
