glmark2-es2 benchmark performance on c0/c1

[hunterhu]

Greetings,

I have a c0 board and plan to use it on an embedded project. I have used the ubuntu-16.04 core rootfs to build up my own customized minimum xfce4 desktop environment, where I can save more than 2.5GB storage space compared with official ubuntu-mate release from Hardkernel.

I have followed the wiki page to build the kernel:
https://wiki.odroid.com/odroid-c1/softw ... ing_kernel

Code: Select all

$ git clone --depth 1 https://github.com/hardkernel/linux.git -b odroidc-3.10.y
$ cd linux
$ make odroidc_defconfig
$ make <-j4>
$ make <-j4> modules
$ make uImage

I have installed the user space drivers related with Mali by following the minimal image wiki:
https://wiki.odroid.com/odroid-c1/os_im ... tu/minimal

Code: Select all

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D986B59D
echo "deb http://deb.odroid.in/c1/ xenial main" > /etc/apt/sources.list.d/odroid.list
apt-get update
apt-get install mali-x11 xserver-xorg-video-mali

The installed versions of the 2 packages are:

mali-x11: Version: 20160906-r6p2-ceeaf8a-23
xserver-xorg-video-mali: Version: 20160712-fa6394b-5

After some tweaks to make mali driver work instead of mesa-egl:

1. move mesa-egl out of the way

Code: Select all

sudo mv /usr/lib/arm-linux-gnueabihf/mesa-egl/ /usr/lib/arm-linux-gnueabihf/.mesa-egl

2. add odroid user to video group

Code: Select all

sudo usermod -a -G video odroid

3. Create udev rules to access mali and ump devices: /etc/udev/rules.d/10-odroid-mali.rules

Code: Select all

KERNEL=="mali",SUBSYSTEM=="misc",MODE="0777",GROUP="video"
KERNEL=="ump",SUBSYSTEM=="ump",MODE="0777",GROUP="video"

Then install the glmark2-es2 benchmark tool:

Code: Select all

sudo apt-get install glmark2-es2

Run the glmark2-es2 on a screen size of 480x272

Code: Select all

glmark2-es2 -s 480x272

the benchmark score is only

glmark2 Score: 108
=================

compared with official ubuntu mate image performance

glmark2 Score: 221
=================

ubuntu-mate official image kernel version is at 3.10.96, and mali-x11 is at 20160712-r5p0-61d4e9c-21

compared with the build from the 3.10.y kernel source and installed from the repo, kernel is at 3.10.107, and mali-x11 is at 20160906-r6p2-ceeaf8a-23

When I paired my built kernel 3.10.107 and installed mali-x11 r6p2 with the rest of the ubuntu-mate image, glmark2-es2 achieved a bit higher score at 184, which indicates something else within the ubuntu-mate image also play a role and make a difference.

Questions: what should I do to reproduce the full mali performance within official ubuntu-mate image? do I miss any packages? do I miss any configurations? or anything else.

Thank you for your help,
Hunter

Did you try different Mate compositor options?
Also check the CPU governor too.

[hunterhu]

Thanks for the tips.

Indeed, after I disabled xfce4 compositor, my minimum customized xfce4 achieved a score of 215 with the glmark2-es2 benchmark tool.

I did overclock the cpu frequency to 1.824GHz from 1.536GHz, which achieved some improvement, but the system start to show instability.

Glad to hear the score got over 200pts.
Remove J8, if you use the DC barrel jack for the power input.

It makes more stable power path and reduced the instability obviously on my test cases.
