GPU
Sections
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 paltform.
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 MT8395 P1V6 (Genio 1200) demo board 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 v22.1, MT8395 P1V6 (Genio 1200) demo board. You might get different operation result depends on what platform you currently use.

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 MT8395 P1V6 (Genio 1200) demo board 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. DVFS can help to reduce the power consumption by dynamically adjusting voltage and frequency of the GPU.

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

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 MT8395 P1V6 (Genio 1200) demo board, 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 you can also find source code from weston github

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.
Default it is not enabled, please add following change in $BUILD_DIR/conf/local.conf to build and install glmark2 into image.
