GPU
This chapter describes common information and instructions of GPU on IoT Yocto, such as command to query GPU hardware information, command to find EGL, GLES support details and so on.
But GPU on different platforms may have some platform-specific instructions or test results. For example, you will get different benchmark results on different platforms. Please find section: Device-Dependent to find more details about difference of GPU on each platform.
Note
Starting from IoT Yocto v24.0, we no longer specifically reserve memory of Contiguous Memory Allocator (CMA) heap for GPU usage. The size of reserved memory is very difficult to estimate. Therefore, we allow the GPU to directly use the system memory instead of the reserved CMA.
GPU Hardware Specification
Please refer to the SoC Platforms to find GPU specifications.
GPU Identification
GPU Hardware Information
You can use following cmd: cat /sys/class/misc/mali0/device/gpuinfo to determine the GPU hardware you are using.
Take Genio 1200-EVK as an example:
cat /sys/class/misc/mali0/device/gpuinfo
Mali-G57 5 cores r0p1 0x9091
Note
All cmd operations presented in this chapter are based on the IoT Yocto v24.0, Genio 1200-EVK. You might get different operation result depends on what platform you currently use.
EGL/OpenGL ES Information
To determine OpenGL ES support details, you can query it by launch weston --backend=drm-backend.so then you could get following information:

Adjust GPU Frequency
The Mali GPU kernel driver supports devfreq-based Dynamic Voltage and Frequency Scaling (DVFS) support using the in-kernel devfreq framework.
Take Genio 1200-EVK as example, the Mali GPU is already integrated into the generic clock framework and the common regulator API and Operating Performance Points (OPPs)
have been registered on the Mali device-tree node. You can find Mali GPU node and available frequencies and supplied voltages are defined in OPPs table
(gpu_opp_table) in device tree overlay. DVFS can help to reduce the power consumption by dynamically adjusting voltage and frequency of the GPU.

Echo value of max_freq and min_freq.
# set max frequency to 560000000
echo 790000000 > /sys/devices/platform/soc/13000000.mali/devfreq/13000000.mali/max_freq
# set min frequency to 560000000
echo 640000000 > /sys/devices/platform/soc/13000000.mali/devfreq/13000000.mali/min_freq
Set Current Frequency
By default the simple_ondemand governor is selected as the default governor, frequency changes automatically based on the system load.
For user specific GPU frequency, it can be done only for userspace governor. So you have to change governor to userspace, then set frequency to GPU.
Note
More in depth documentation about each governor can be found in the linux kernel documentation here: https://www.kernel.org/doc/Documentation/cpu-freq/governors.txt
# query current frequency before operation
cat /sys/devices/platform/soc/13000000.mali/devfreq/13000000.mali/cur_freq
880000000
# change governor to userspace to allow the user to set the gpu to a specific frequency
echo userspace > /sys/devices/platform/soc/13000000.mali/devfreq/13000000.mali/governor
# set frequency
echo 700000000 > /sys/devices/platform/soc/13000000.mali/devfreq/13000000.mali/userspace/set_freq
# check current frequency after operationn
cat /sys/devices/platform/soc/13000000.mali/devfreq/13000000.mali/cur_freq

Performance Mode
Performance mode means forcing the CPU and GPU to run at maximum frequency. For GPU, regardless of the
platform, the cmd: echo performance > /sys/devices/platform/soc/${Mali GPU node}.mali/devfreq/${Mali GPU node}.mali/governor
can be used to make the GPU statically to the highest frequency.
echo performance > /sys/devices/platform/soc/13040000.mali/devfreq/13040000.mali/governor
But for the CPU, different platforms have different instructions to make the CPU statically to the highest frequency. Please refer to the corresponding section according to the platform:
For Genio 350-EVK, run at performance mode.
For Genio 510/700-EVK, run at performance mode.
For Genio 1200-EVK, run at performance mode.
Query GPU Utilization
Get GPU utilization by query gpu_utilization attribute in GPU device node. The result will be Mali GPU utilization:${utilization}@${current_frequency}
cat /sys/devices/platform/soc/13000000.mali/gpu_utilization
Mali GPU utilization:60@390000000Hz
OpenGL ES Application
On IoT Yocto, there are several OpenGL ES applications can used to check that GPU is running and well integrated within the Wayland/Weston system.
weston-simple-egl
It’s a simple demonstration GLES program that draws a rotating colorized triangle on a transparent Wayland window.
You can find it in weston package (aiot-yocto/src/poky/meta/recipes-graphics/wayland/weston_${version}.bb)
and the source code from the weston repository.

westonservice if it is not started yet.
For Genio 350-EVK, cmd to start weston.

kmscube
It is a simple demonstration GLES program for how to drive bare metal graphics without a compositor (Wayland), using DRM/KMS (kernel mode setting), GBM (graphics buffer manager) and EGL for rendering content using OpenGL ES.
You can find it in kmscube package (aiot-yocto/src/poky/meta/recipes-graphics/kmscube/kmscube_git.bb).
And you can also find source code from mesa gitlab.

GPU Benchmark
glmark2
IoT Yocto provides glmark2 which is an OpenGL 2.0 and ES 2.0 benchmark.
It offers a suite of scenes that can be used to measure many aspects of OpenGL (ES) 2.0 performance.
By default, glmark2 is already prebuilt into the rity-demo-image, or you can also modify the $BUILD_DIR/conf/local.conf
and add the following change to build and install glmark2 into the image.
IMAGE_INSTALL_append = " glmark2 "
If glmark2 is enabled, you can use cmd: whereis to find glmark2-es2-wayland and glmark2-es2-drm on board.
glmark2-es2-wayland: run benchmark as a Wayland client.glmark2-es2-drm: run benchmark as a native DRM/GBM OpenGL ES application.
whereis glmark2-es2-wayland
glmark2-es2-wayland: /usr/bin/glmark2-es2-wayland
whereis glmark2-es2-drm
glmark2-es2-drm: /usr/bin/glmark2-es2-drm
Launch glmark2-es2-wayland
Start
westonservice if it is not started yet.
systemctl start weston
Before running
glmark2-es2-wayland, we set both the CPU and GPU to performance mode..Launch
glmark2-es2-wayland. By default, it renders various scenes in a output window with the resolution of 800x600, but the complexity of these scenes does not make the GPU to achieve a 100% usage rate. Therefore, we let glmark2 render to a window with higher resolution: 1920x1080, performing benchmarks when the GPU usage rate is close to 100%. You can find benchmark score when it finishes.
glmark2-es2-wayland -s 1920x1080
=======================================================

=======================================================
glmark2 Score: 2192
=======================================================
Launch glmark2-es2-drm
Stop
westonservice if it already started.
systemctl stop weston
Before running
glmark2-es2-drm, we set both the CPU and GPU to performance mode.Launch
glmark2-es2-drmwith specified visual config. Default it renders scene at fullscreen resolution and fps is locked to the display refresh rate. You can find benchmark score when it finishes.
glmark2-es2-drm --visual-config 'red=8:green=8:blue=8:alpha=0:buffer=24:depth=24:stencil=8'
